Equilibrium chemistry Essays

Abstract This assignment focuses on how deviance forms a part of major social institutions in our society i.e., religion, education, government, economy and family. It attempts to explore so, through different perspectives and live examples/ situations persisting in the India society. I have also tried to give examples of situations that I have witnessed in the agency I am placed, Crime against Women (CAW) Cell. What is Deviance? Though there is no exact or approved definition of Deviance but the

The purpose of this experiment is to calculate an equilibrium constant for a chemical reaction by observing “Le Chatelier’s Principle” in a chemical reaction. Equilibrium is caused when a chemical reaction does not go to “completion,” but when both reactants and products exist. According to research students of the University of Oxford, “equilibrium does not imply that all chemical activity has stopped, only that forward and reverse reactions are proceeding at the same rate, so no further net change

Master dilution techniques and proper use of volumetric glassware. Practice calculation of concentrations and set up of ICE table. Use spectrophotometer to evaluate relationships of solution

oneway reaction, however a reversible reaction will eventually reach a point of equilibrium where the products are reactant are produced at the same rate. ( AS and A level Chemistry book) Dynamic equilibrium occurs in a closed system where the amounts of products and reactants are not changing anymore and even though there is no visible change the chemical reaction is continually happening known term being equilibrium, where both forwards and backwards reactions are produced at the same rate. The

Throughout history, dating back to 3600 BC, games of chance and gambling have existed ("Introduction- Gambling and Probability"). Since their invention, people have tried to decipher ways to predict the outcome of such games, thus a need to determine the likelihood of winning in games such as these evolved. The method created to suit this need is known as probability theory. Probability theory has been developed over hundreds of years, and is used to predict possible outcomes and assist in daily

Enzymes are very valuable to the metabolic process. Enzymes are protein catalyst that lowers activation energy and speed up chemical reactions. Knowing what conditions affect enzymes will help further knowledge in what enzymes are and how they work. Catecholase was used in both experiments. The absorbance rate of each test tube was measured at 420 nm. The first experiment showed how pH affects enzyme reaction rate. This experiment found that the optimal pH for catecholase is pH 10. However, catechol

Introduction: There are a number of environmental parameters that can affect enzyme activity and its process. Enzymes are substances made in by an organism that serves as a catalyst and quickens the biochemical reaction to occur. When a catalyst is brought into the picture, it speeds up the time needed for said reaction to occur, making the enzyme a “helper” for reactions. Enzymes and substrates are closely related in the sense that both join together to help bring the end result of the reaction

interaction of the Allies and the Axis during WWII. Finally, some of the crucial developments of game theory were brought by the work of the late John Nash, who in his 1950 treatise on non-cooperative games introduced a concept of equilibrium which we now know as the Nash equilibrium . Before we

The origins of the Poverty measure While studying the impact of minimum wage increases on poverty, it is of significant importance to understand how poverty is measured. According to the definition of poverty – “The U.S. Census Bureau determines poverty status by comparing pre-tax cash income against a threshold that is set at three times the cost of a minimum food diet in 1963, updated annually for inflation using the Consumer Price Index (CPI; see the last section of this FAQ for an explanation

Experiment 2: Preparation and Spectrophotometric Analysis of Copper(I) Iodide Abstract: This experiment aims to determine the concentration of “Purified CuI” sample. Crude CuI is obtained by reacting CuSO4.5H2O with KI and Na2S2O3 in de-ionized water. A series of decanting and centrifugation is carried out to extract the crude CuI. Crude CuI was later purified by dissolving it in hot KI solution. The solution was later transferred into de-ionized water and placed in an ice bath to allow for re-precipitation

While I was in high school I struggled in AP Chemistry and AP Language and Composition. In AP Chemistry, I struggled with solving for the K value in equilibrium, in which I got help by going to the tutors in the school library after school. The tutor helped me out by showing me how to understand the examples in my notes and then by helping me apply the same technique of solving that was on the notes to the problems that were assigned to me as homework. This is the only reason why my AP Chem grade

ABSTRACT: This experiment investigated the effects of pH, temperature and ionic strength on the protolytic equilibrium reaction between the dianionic and anionic forms of fluorescein in aqueous solution. The effects were shown from the absorption and fluorescence spectra of each sample. The absorption and fluorescence spectra showed that the dianion species has the higher absorptivity and fluorescence than the anion species. Fluorescein solutions that contains more dianion species generated absorption

- Medicinal Chemistry - Question No. 3. Define the Hammett Constant and the hydrophobic (Hansch) substituent constant. Comment on how inductive and mesomeric polar effects are treated in substituted aromatic systems. A quantitative structure-activity relationship (QSAR) is an equation which correlates measurable or calculable physical or molecular properties to some specific biological activity. Once this relationship has been determined, it is possible to predict the biological activity of related

Game Theory and the Prisoners’ Dilemma Strategic Rationality In this chapter, Daniel Little indicates that under circumstances of uncertainty and risks, decision-makers attempt to maximize utility through collecting information of the utility and analyzing the probability of each feasible choice. Finally the maximum expected payoff of outcomes is given to the decision-maker since all other decision makers also made the rational decisions. Also strategic rationality is embodied on interactive social

Essay #2 Progressing through life, view the twist and turns on the path that must be followed. Why must these obstacles be placed where they are and what makes it different from a perfectly straight path? Playing a board game is just the same as the journey of life. It wouldn’t be the same if all of it was just one simple path. There would be no point of playing. There would be no way to challenge yourself and make it competitive. It would be nearly impossible to learn anything from it. Just as without

swerve away. According to Wikipedia, (2018), it is reported that "this unstable situation can be formalized by saying there is more than one Nash equilibrium, which is a pair of strategies for which neither player gains by changing his own strategy while the other stays the same". In light of this, the drivers of either car assume to know the equilibrium strategy of the other driver meanwhile in the event that they both decide to change their strategy, there is no certainty that either would arrive

A video I viewed of this experiment stated that after it eats the shell away, the egg could turn out to be rubbery, kind of like a bouncey ball. Due to history and past experimentation, the experiment of the naked egg illustrates the concepts of chemistry. The process to make a naked egg is very simple. Place your egg in a cup and carefully fill the cup with vinegar. Make sure that you completely cover the egg with vinegar. If the egg begins to float, be sure to have enough vinegar in the cup to mostly

every day with the task of identification of different materials from unknown sources. An area commonly used in forensic chemistry is partitioning, which is the separation of mixtures using a set of laboratory techniques. Partitioning takes a substance and divides it into parts. For partitioning to take place an analyte of a greater affinity for 1 phase over the other equilibrium conditions are manipulated to maximize partitioning. They all have a stationary phase (a solid, or a liquid supported on

Bradley Trotter & John Fussell Chem 1121-42 March 29th, 2018 Identity of an Unknown Weak Acid Lab Report Introduction: Being able to determing the molar mass of an unknown solution is one of the many ways to identify what the unknown solution is. The use of titrations and LoggerPro, make extrapolating data more precise and will produce more accurate results than if done manually. By comparing the caculated molar mass, and pKa values, with accepted values a hypothesis can be made to the identity
