Chemistry 12 Santa Monica College Determination of Kc for a Complex Ion Formation Objectives • • Find the value of the equilibrium constant for formation of FeSCN2+ by using the visible light absorption of the complex ion. Confirm the stoichiometry of the reaction. Background In the study of chemical reactions‚ chemistry students first study reactions that go to completion. Inherent in these familiar problems—such as calculation of theoretical yield‚ limiting reactant‚ and percent yield—is

Purpose. The purpose of this lab was to understand equilibrium. To do this‚ you must find the equilibrant of the resultant of three vectors‚ both mathematically and graphically and test the results. Procedure: A) Put the weights necessary for each of the vector forces on each hook. B) Set the wheels of the force table at the proper angles‚ including the calculated equilibrant. C) When placing the hooks on the wheels‚ be careful to hold the table in place so it does not flip over. D) To test

G = 55 M = 10 2. Given C = 40 + 0.5(Y-T) I = 60 G = 55 T = 10 + 0.2Y What is the value of equilibrium income level ? If both autonomous consumption (expenses) and T increase by the same amount‚ equilibrium Y will increase‚ decrease or being unchanged? Why? 3. In a

Hardy-Weinberg Equilibrium One of the most difficult concepts to understand about the process of evolution is how changes in the genetic composition of a population affect the phenotypic composition of a population‚ and how both ultimately act to allow evolution of the species. Charles Darwin’s theory of evolution emphasizes that populations‚ not individuals‚ evolve. The purpose of my experiment was to test the allele and genotype frequencies. Alleles for a gene are represented by letters of

Introduction In biology there is a scientific principle known as the Hardy-Weinberg Equilibrium. In this principle it is believe that allele frequencies will remain the same among the different generations‚ depending on whether or not the five assumptions are taking place. In this experiment‚ students put the Hardy-Weinberg theory to the test. Out of the five assumptions‚ only two were conducted in the experiment‚ Natural Selection and Mutation. For those that do not know‚ the Hardy-Weinberg

Ansari Island Civilization In the article Island Civilization: A vision for human occupancy of Earth‚ Roderick Frazier Nash describes how the earth that was once a peaceful planet with freedom of living for every specie turned out to be the earth we are living in now. Had human beings more farsighted they wouldn’t have taken wilderness as something that must be controlled. Nash explains how the mankind built fences and roads to control the wild‚ and soon there came a time when United States Census

John Nash and Einstein are examples of geniuses in life that with their innovative ideas were able to accomplish great accolades in their own field of work. Still‚ John had a serious problem‚ his mental sickness of schizophrenia. His sickness and his severe social problems were a big problem for his life. He would be affected by the ideas of having 3 imaginary characters that suggested his crazy personality and would make him have feelings of ambivalence towards different persons. John Nash and

Demand‚ Supply‚ Market Equilibrium and Elasticity A. Elasticity of demand is shown when the demands for a service or goods vary according to the price. Cross-price elasticity is shown by a change in the demand for an item relative to the change in the price of another. For substitutes‚ when there is a price increase of an item‚ there is an increase in the demand for another item. When viewing complements‚ if there is an increase in the price of an item‚ the demand

If supply curve shifts‚ how it is going to affect the market equilibrium. How market will resettle to the new equilibrium?? Changes in price result in movement along the supply curve‚ changes in other relevant factors cause a shift in supply‚ a shift of the supply curve to the left or right such a shift results in a change in quantity supplied for a given price level. If the change causes an increase in the quantity supplied at each price level. If the change causes an increase in the quantity
