Law of Definite Proportions Definition

Law of Definite Proportions Definition The law of definite proportions, together with the law of multiple proportions, forms the basis for the  study of stoichiometry  in chemistry. The law of definite proportions is also known as Prousts law or the law of constant composition. Law of Definite Proportions Definition The law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. The mass ratio of elements is fixed no matter where the elements came from, how the compound is prepared or any other factor. Essentially, the law is based on the fact that an atom of a particular element is the same as any other atom of that element. So, an atom of oxygen is the same, whether it comes from silica or oxygen in air. The Law of Constant Composition is an equivalent law, which states each sample of a compound has the same composition of elements by mass. Law of Definition Proportions Example The law of definite proportions says water will always contain 1/9 hydrogen and 8/9 oxygen by mass. The sodium and chlorine in table salt combine according to the rule in NaCl. The atomic weight of sodium is about 23 and that of chlorine is about 35, so from the law one may conclude dissociating 58 grams of NaCl would produce about 23 g of sodium and 35 g of chlorine. History of the Law of Definite Proportions Although the law of definite proportions may seem obvious to a modern chemist, the manner in which elements combine was not obvious in the early days of chemistry through the end of the 18th century. French chemist Joseph Proust (1754–1826) is credited with the discovery, but English chemist and theologian Joseph Priestly (1783–1804) and French chemist Antoine Lavoisier (1771–1794) were the first to publish the law as a scientific proposal in 1794, based on the study of combustion. They noted metals always combine with two proportions of oxygen. As we know today, oxygen in the air is a gas consisting of two atoms, O2. The law was hotly disputed when it was proposed. French chemist Claude Louis Berthollet (1748–1822) was an opponent, arguing elements could combine in any proportion to form compounds. It wasnt until English chemist John Dalton (1766–1844)s atomic theory explained the nature of atoms that the law of definite proportions became accepted. Exceptions to the Law of Definite Proportions Although the law of definite proportions is useful in chemistry, there are exceptions to the rule. Some compounds are non-stoichiometric in nature, meaning their elemental composition varies from one sample to another. For example, wustite is a type of iron oxide with an elemental composition varying between 0.83 and 0.95 iron atoms for each oxygen atom (23%–25% oxygen by mass). The ideal formula for iron oxide is FeO, but the crystal structure is such that there are variations. The formula for wustite is written Fe0.95O. Also, the isotopic composition of an element sample varies according to its source. This means the mass of a pure stoichiometric compound will be slightly different depending on its origin. Polymers also vary in element composition by mass, although they are not considered true chemical compounds in the strictest chemical sense.

Leonard Susskind - Theoretical Physicist

Leonard Susskind - Theoretical Physicist In 1962, Leonard Susskind earned a B.A. in physics from City College of New York after transitioning from his plan to get a degree in engineering. He earned his Ph.D. in 1965 from Cornell University. Dr. Susskind worked at Yeshiva University as an Associate Professor from 1966 to 1979, with a year at University of Tel Aviv from 1971 to 1972, before becoming a Professor of Physics at Stanford University in 1979, where he remains to this today. He was awarded the Felix Bloch Professorship of Physics since the year 2000. String Theory Insights Probably one of Dr. Susskinds most profound accomplishments is that hes credited as one of the three physicists who independently realized, back in the 1970s, that a certain mathematical formulation of particle physics interactions seemed to represent oscillating springs ... in other words, hes considered one of the fathers of string theory. He has done extensive work within string theory, including the development of a matrix-based model. Hes also responsible for one of the more recent discoveries in the exploration of theoretical physics, the holographic principle, which many, including Susskind himself, believe will provide great insights into how string theory applies to our universe. In addition, in 2003 Susskind coined the term string theory landscape to describe the set of all physically possible universes that could have come into being under our understanding of the laws of physics. (At present, this could contain as many as 10500 possible parallel universes.) Susskind is a strong proponent of applying reasoning based upon the anthropic principle as a valid means to evaluate which physical parameters its possible for our universe to have. Black Hole Information Problem One of the most troubling aspects of black holes is that when something falls into one, it is lost to the universe forever. In the terms that physicists use, information is lost ... and that isnt supposed to happen. When Stephen Hawking developed his theory that black holes actually radiated an energy known as Hawking radiation, he believed that this radiation would be insufficient to actually resolve the problem. The energy radiating out from the black hole under his theory would not contain enough information to fully describe all of the matter that fell into the black hole, in other words. Leonard Susskind disagreed with this analysis, believing quite strongly that the conservation of information was so important to the underlying foundations of quantum physics that it could not be violated by black holes. Ultimately, the work in black hole entropy and Susskinds own theoretical work in developing the holographic principle have helped to convince most physicists - including Hawking himself - that a black hole would, over the course of its lifetime, emit radiation that contained the full information about everything that ever fell into it. Thus most physicists now believe that no information is lost in black holes. Popularizing Theoretical Physics Over the last few years, Dr. Susskind has become more well-known among lay audiences as a popularizer of advanced theoretical physics topics. He has written the following popular books on theoretical physics: The Cosmic Landscape: String Theory and the Illusion of Intelligent Design (2005) - This book presents Susskinds view of how string theory predicts a vast string theory landscape and how the anthropic principle can be applied to evaluate the various physical properties of our universe against all of the assorted possibilities. This is described above in the string theory section.The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics (2008) - In this book, Susskind describes the black hole information problem (described above), framed as an intriguing narrative about a disagreement within the theoretical physics community ... one which has taken decades to resolve.The Theoretical Minimum: What You Need to Know to Start Doing Physics with George Hrabovsky (2013) - A math-based introduction to the fundamental concepts within classical mechanics, such as conservation of energy and symmetries in physical laws, which is intended to lay the groundwor k for what someone would need to know to proceed to the next level in physics. This is based on lectures that are available online, as described below. In addition to his books, Dr. Susskind has presented a series of lectures that are available online through both iTunes and YouTube ... and which provide the basis of The Theoretical Minimum. Here is a list of the lectures, in roughly the order that I would recommend viewing them, along with links to where you can view the videos for free: Classical Mechanics (YouTube) - A 10-lecture series focusing on the fundamentals of classical mechanicsThe Theoretical Minimum: Quantum Mechanics (YouTube) - A 10-lecture series that tries to understand what physicists know about quantum mechanicsSpecial Relativity (YouTube) - A 10-lecture series explaining Einsteins theory of special relativityGeneral Relativity (YouTube) - A 10-lecture series that lays out the modern theory of gravity: general relativityParticle Physics: Standard Model (YouTube) - A 9-lecture series focusing on the Standard Model of particle physicsCosmology (YouTube) - A 3-lecture series focusing on what we know and understand about the history and structure of our universeString Theory and M-Theory (YouTube) - A 10-lecture series focusing on the fundamentals of string theory and M-TheoryTopics in String Theory (YouTube) - A 9-lecture series focusing on the fundamentals of string theory and M-Theory As you may have noticed, some of the themes repeat between lecture series, such as the two different lecture sets on string theory, so you shouldnt need to watch them all if there are redundancies ... unless you really want to.

Communication Process in the workplace Essay Example | Topics and Well Written Essays - 1250 words

Communication Process in the workplace - Essay Example In order to effectively deal with the managerial challenges that face their firms, managers emulates effective communication that is also essential in creation of a strong culture for example in aspects dealing with ethics (Laurie, 1989). AC 1.2 The communication cycle starts from the sender. This is the person who provides the first message that is coded in nature. For the sender to effectively send his or her message, he or she must select an appropriate medium or channel of communication. Through the medium, the message is directed to the receiver who then decodes the message in order to understand it. The receiver then sends a feedback to the sender, an indication that the receiver has understood the message. The communication cycle starts once more. AC 1.3 In their efforts to enhance communication in the work place, managers are faced with various barriers that affect their communication process. One of the major barriers to communication is omission of information by the sender . In case the sender omits a certain point during the communication it may affect all stages in the communication cycle making it difficult for the receiver to understand it. The second barrier is communication overload. ... AC 1.4 Thus, there is need to adopt various strategies to overcome the potential barriers to communication. For example, to overcome the barrier incurred due to use of contradicting signs, sender must use direct simple language that easily decoded by the receiver. Additionally, senders must emulate the culture of use of face-to-face communication that is known to be direct and easily understandable by the receivers (Laurie, 1989). Similarly, senders must reinforce their words with actions especially when communicating to large audience. Section 2: Understanding the methods of communication AC 2.1 One of the major methods of written communication is email. This entails use of internet sites such as Gmail and yahoo to send messages to the receivers. For effective communication through email, the sender and the receiver must have email addresses. Similarly, they should have an access to a computer with an internet connection. Emails are used to inform the applicants for example on the r esults of the interview. It can also be used by departmental managers to inform the employees on the date and venue of a meeting. Another example of a written communication is magazines. This entails writing a message on a booklet with the intention of informing the public or the consumers about the brands available in the market as well their prices and distribution centres. A good example of a method of oral communication is face to face. In a workplace, oral communication is used during the interviewing of new employees as well as during the training of the existing workers. AC 2.2 One of the main advantages of written methods of

Lake Conservation And Urban Water Management Environmental Sciences Essay

Lake Conservation And Urban Water Management Environmental Sciences Essay Water is one of the most important substances on the earth. Water generates the hydrosphere, circulates in the atmosphere, and infiltrates deep into the ground and moves through the lithosphere and sustains the biosphere. Fresh water source like lake is a renewable resource following the hydrological cycle, it is not evenly distributed on the earths surface. Lakes are large water bodies, which have an important impact on human emotions such as security, happiness and creative aspects of behavior. These are not mere decorative bodies but are biological and psychological necessities. Environmentally lakes are one of the important ecosystems. They play a significant role in recharge and maintenance of ground water table. They have a great recreational potential in the form of water sports, boating etc. in todays fast and stressful life style. In case of emergency, they can serve as source of water for fire fighting etc. They can also be used for Aquaculture as a source of income. They a dd to the beauty of the city promoting tourism. The lakes and reservoirs, all over the country are facing degradation. The degradation is due to encroachments and eutrophication (from domestic and industrial effluents) and silt accumulation. There has been a considerable increase in urban population especially after industrial revolution. The human settlements have taken place in and around the ponds and lakes to mitigate their demands, resulting in contaminating the water sources. The need of Conservation and Management of Lakes is therefore rightly understood by the world community and the issues relating Conservation of lakes are on the anvil. In Lentic or lake ecosystems, the aging process is just the reverse of lotic or river systems. Where as streams tend to get wider and deeper as they age, lakes tend to get shallower and the banks extend into what was originally open water. Natural filling is generally due to wind blown materials (soil, leaves, etc.) entering the system, sediment input by terrestrial run off, aquatic plant and animal debris and eutrophication. Eutrophic lakes When the balance is upset between photosynthesis and decomposition due to enrichment of water by inorganic plant nutrients, either too much organic material accumulates without getting decomposed adequately or too many bacteria are present and an overabundance of decomposition occurs, the lake is classed as Eutrophic. They are considered to be middle aged systems. They are relatively shallow in comparison to Oligotrophic lakes. They have a silty or mud bottom and have sufficient nutrients to support a large population of animals. The accelerated or cultural eutrophication of several waterbodies is caused by human activity. Large quantities of mineral nutrients and organic matter are added to the waterbodies in the form of sewage effluents, organic wastes, agricultural run-offs, excreta and The Process of Eutrophication fertilizers sewage (liquid domestic Industrial waste) minerals esp. nitrates minerals esp. nitrates eutrophication algal bloom competition for light consumers canà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢t consume fast enough dead plants dead algae detritus more decomposers use up oxygen by aerobic respiration (increased BOD) aerobes die invertebrates, fish etc. anaerobic bacteria thrive, release NH4,CH4,H2S exudates of animals and humans etc. These provide plenty of phosphates, nitrates (mostly of fertilizers applied to agricultural lands, domestic sewage etc.) which lead to exuberant growth of algae and other water plants. A rich microbial and animal population also develops. The process of natural Eutrophication which is generally very slow , thus gets accelerated. Silt and organic debris accumulates at the bottom and the system turns into a shallow muddy pond, then to a marsh and finally into a dry land. Thus a waterbody which could have been useful as a reservoir of fresh water and could have helped the growth of fish etc. for hundreds of years becomes totally useless within a span of few years only. Sources of Lake Pollution: The sources of Pollution can be classified as fixed point sources and Non-point Sources EFFECTS OF EUTROPICATION Undesirable effects of Eutrophication Algal blooms: The decaying algae, fish, planktons and other organisms cause foul smell. On depletion of oxygen level and on exhausting nitrate oxygen, sulphates are reduced as a last resort to yield hydrogen sulphide which results in bad smell and putrefied taste of water. The lakes become aesthetically unpleasant. Plant growth and silt hinder recreation activities. Rate of sedimentation increases, which shortens the life span of lakes. Mosquito nuisance increases causing health hazards to nearby residents. Steps to Control Eutrophication Preventive Measures Effective waster water treatment and removal of nutrients like nitrogen and phosphorous before discharging the sewerage into waterbodies. Controlling the recycling of nutrients through harvest. Effective disposal of organic matter as sludge. Developing phosphate-free detergents for domestic use. Adopting effective Physico-chemical methods for removal of dissolved nutrients such as nitrogen phosphorous compounds. Overcoming the temptation of over-fertilization. Remedial Measures for Eutrophication: Controlling eutrophication by applying algaecides such as copper Sulphate, chlorine etc. on susceptible surface waterbodies. Removal of the algal bloom by dredging mechanical means.. Underwater weed cutters mounted on boats can be used to remove rooted aquatic plants. Dredges can be used to remove sediments to prevent recycling of nutrients and also for deepening of the lake. Sealing of Lake Bottom with polythene sheeting to prevent release of nutrients from sediments. Providing aeration artificially to increase the DO levels in the lake water. Diluting and or flushing the lake with water from Oligotrophic source. Using Bio remediation techniques. Arresting of nutrients: Biological removal using the ability of some microorganism to take up phosphorous in excess of their immediate nutritional requirements and store it within the cells in the form of polyphosphates. The sludge thus formed can be removed from the system. Water Quality Network Central Pollution Control Board started national water quality monitoring in 1978 under Global Environmental Monitoring System (GEMS), Water Programme. Monitoring, Programme was started with 24 surface water and 11 groundwater stations. Parallel to. GEMS, a National Programme of Monitoring of Indian National Aquatic Resources (MINARS), was started in 1984, with a total of 113 stations spread over 10 river basins. The present network comprises of 870 stations on rivers, lentic water bodies and subsurface waters are elaborated. The number of locations on mainstream of the major river and their tributaries, medium and minor rivers, lakes, ponds, tanks and other water bodies is given in parenthesis. It is estimated that there is about 45,000 riverine length in India out of which about 6500 km length is having BOD higher than 6 mg/1 and can be branded as polluted, another 8500 km length is moderately polluted having BOD in the range of 3 to 6 Mg/l, and remaining about 30,000 km is relativ ely clean having BOD of 3 or Management of lake Trophic State Index in Conservation of Lake Ecosystems. When faced with challenges of trying to describe and organize what is known about the many varied diverse waterbodies, scientists have developed the Trophic State Index (TSI) Classification. This requires minimum data and is generally easy to understand. In the Index total chlorophyll indicates algal biomass and biological productivity: and water clarity is determined by Secchi disc, which indicates the level to which light can penetrate; and algae can photosynthesize. TSI is the best and easy method. The range of the index between 40-50 is usually associated with mesotrophy (moderate productivity); values greater than 50 are associated with eutrophy (high productivity), values less than 40 are associated with oligotrophy (low productivity). Thus, the Trophic State Index (TSI) can serve an important tool in conservation of Lakes. Assessing the Hydrologic Characteristics of Lake Catchment Using GIS Land use change is a dynamic process and if anthropogenic it has most often adverse effects on ecological hydrological processes. For better understanding the impacts of changing physical characteristics on the hydrologic process, geospatial tools like remote sensing and GIS have been found useful. World Lake Vision The key to sustainable use of our lakes and wetlands lies in finding a balance between the water needs of human beings and the ability of nature to meet same over the long term. The WLV has articulated the basic action plan for sustainable use of lake and wet land resources in the form of seven basic principles. Seven Principles for the sustainable lake management are related with:- Harmony between Nature Man. Drainage Basin. Preventive approach to problem solving. Policy based on sound Science. Conflict Resolution. Stake holderà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s involvement. Good governance. If future water security is to be achieved, there is an urgent need to initiate steps for protection, conservation and sustainable use of precious water resources in general and lakes in particular. Powai Lake A Case Study The Powai Lake of Mumbai Municipal Corporation of Greater Mumbai (MCGM) is located about 27 Km. away in the North East of Mumbai City. It is an artificial reservoir formed by constructing a masonry dam between two hillocks across the Powai basin in the year 1891. The watershed area of the Powai Lake is 661 hectors. The top level of dam is 58.5 Mtrs. THD (Town Hall Datum), length is about 110 mtrs. and height is varying from 3mtrs.(Min.) to 6.00 Mtrs(Max.).The lake deteriorated due to accelerated growth of residential and commercial premises around the lake and quarrying activities in the catchments area. Also there was no proper control on surrounding. Thus, there was an urgent need to evolve the strategy to improve and maintain the Powai lake surroundings. In the year 1995, under the national Lake Conservation Plan of the Ministry of Environment and Forests (MoEF) Government of India, the Powai Lake of MCGM was reviewed and identified for revival and improvements. The Powai Lake of Mumbai which was deteriorated due to eutrophication is now recovered using bioremediation and aeration technique.

Cause and Effect of Earthquakes Essay

The ground trembles, shakes and growls. Pictures that were once hanging so beautifully on the wall smash to the ground exploding into glittery slivers of broken glass, roadways break apart, engulfing whatever was in its path, never to be seen again. For many, this would seem to be the makings of a fictional horror movie created by Hollywood with intent to frighten a person and to play with ones senses. For those who live in the areas depicted by film, this is real life, all of the fear and terror of a shaking ground comes to life and people everywhere grab those that are most precious to them and scream â€Å"Earthquake!† According to Lisa Wald (2012), â€Å"an Earthquake is what happens when two blocks of Earth suddenly slip past one another.† Wald also says that the reason the earth shakes when there is an earthquake is â€Å"that the edges of the faults are stuck together, and the rest of the block is moving, the energy that would normally cause the blocks to slide past one another is being stored up. When the force of moving blocks finally overcomes the friction of the jagged edges of the fault and it unsticks, all that stored up energy is released.† Wald goes on further to suggest that this energy is then released into seismic waves, it is these waves that cause the Earth to shake. This shaking, while normal for the Earths development, can be fatal for those who live in it. The damage that is caused by an earthquake can be broken into three specific areas. These areas include the Emotional damage, physical damage and environmental damage. The emotional damage caused by loss is one of the more detrimental areas of concern for humans as they are the ones whose lives are so greatly affected by feeling. People generally tend to have a harder time accepting death if it is spontaneous (Hamilton health sciences, 2000). The grieving process is harder, last longer and is full of disbelief. When natural occurrences such as earthquakes happen, many individuals lose their lives in an instant. Whether it is due to power failure and medical equipment failing, the destruction of homes and buildings and being forced into the street facing other dangers such as wildlife or people with poor intentions, or becoming trapped under rubble from buildings or roadways that have been destroyed. This emotional damage caused makes it far more difficult for the survivors of the earthquakes to move past the tragedy quickly. It may take many hours of grievance counseling for these people to be functional members of society again, to move forward with their lives. Some people develop severe anxiety and fear that an earthquake will hit when they are least expecting it and begin refusing to leave their homes. On the other hand, some individuals feel such a sense of togetherness after loss from an earthquake, they quickly pull together to help other people deal with their losses, searching for those who may still be alive and even assisting with clean up and rebuilding of homes and businesses. They go on to looking for more ways to help their community in the time of need, and really do a great deal to help others get back on their feet. Physical damage is bound to happen to some extent during an earthquake, though architects and engineers are now looking at new ways to make buildings and homes more earthquake resistant for those who live in high quake areas, the cost of such engineering is incredibly costly and not everyone can afford such detail to construction. Many people’s homes, one moment standing proud and tall, end up reduced to rubbles of brick and mortar in a matter of seconds. Cars disappear into what was once a street or roadway never to be seen again. Businesses destroyed, too expensive to repair, force people into lives of poverty. Far too many individuals end up homeless and jobless from natural disasters without their loved ones or their most loved possessions, and have no ability to be able to start from scratch again. Many insurance companies will not cover the damage caused by natural disasters, especially if the property is in an area known to be high in a specific disaster such as earthquakes. If they were to offer this form of protection, it would be at a greater cost to allow a person to rebuild their home or business. In the event of a natural disaster, the consequences could be dire and the insured could be slapped with higher yearly fees and deductibles. A price not many people are prepared to pay with high incidents of poverty in the world. Another of the more detrimental effects of earthquakes is how the environment changes with every quake that occurs. The environment is obviously going to take the largest hit from an earthquake. Localized effects would include forest fires, mudslides, and landslides while greater effects can be felt on the other side of the planet with disasters such as tsunamis. The Asian countries have taken the hardest tolls due to earthquakes, with the largest tragedy being in 2004 when a tsunami that was developed out of a high-scaled earthquake in Sumatra. This tsunami assailed twelve countries, killed over two-hundred and twenty thousand people (Daniel Ten Kate & Berni Moestafa, 2012), and still continues to affect people eight years later. When a tsunami strikes, fatalities are guaranteed. People die by drowning, hypothermia, starvation, and rarely have time to escape their impending death or injury. Beautiful flowers and gardens can be lost forever, sacred tombs, and artifacts washed out to see. Landslides and mudslides may not sound as fatal as a tsunami, however; these occur when the earth shifts and vibrates and causes the land to shift and vibrate with it. Many areas that are high for landslide danger put up protective netting or boarding to prevent the danger of it affecting people in the community, but it is not always possible to contain. They can quickly bury homes and people with no chance of recovery. Fires can be caused by electrical wires being exposed and touching flammable debris, broken gas lines, and power lines and are almost impossible to extinguish with water mains being broken and dust and debris floating through the air feeding and fueling the fires. It is amazing that even a slight shift in the planet can cause such devastation in the world. The shifting of the Earth, while natural, can be fatal to so many objects in its path. Yet it is something that can occur without notice, even with monitoring. The emotional, physical, and environmental damage that can occur is devastating and many people are left homeless, with no income, family, or possessions. Left to fend for themselves in the streets, searching for a way out, attempting to avoid the dangerous wildlife or people they may encounter on their own. Many children cry for their parents, never to see them again. The effects of earthquakes can be greatly reduced if humanity would listen to the scientists or experts on natural disasters. By building more structurally sound buildings and preparing ourselves further for a disaster, we can all benefit from becoming safer during an earthquake.
