Determination of an Equilibrium Constant Abstract: In this experiment, two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium, LeChatlier’s Principle, Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration

Leah Baker English Comp 1210 Critical Analysis September 28, 2011 Critical Analysis of an Ineffective Essay Author, Harriet Davids, of “The Extended School Day” believes all elementary schools should adopt an extended school day policy. Davids main ideas focus on the safety of the children, whether it be in the care of a nanny or home alone, safety is the number one priority. Davids not only states that an extended school day will be beneficial to the parents and the students, but also the

The Wars: Four Elements It was the ancient Greek philosopher, Empedocles, who first established the four elements: earth, water, air and fire. He also stated that everything in the world is structured by and rooted in these four elements. However during times of conflict and violence, humans begin to disturb this harmony. When this happens, the elements stop representing life and start representing a form of destruction. Throughout Robert Ross’s journey in The Wars, Timothy Findley exemplifies

BIO 211 Lab Section 11 February 15, 2012 Effects of Temperature on Enzymatic Activity Abstract Temperature is a measure of kinetic energy. As this movement increases, collision rate and intensity, and therefore reaction rates, increase. This experiment was conducted to determine if there is a minimum temperature that increase kinetic energy and denature enzymes to slow enzymatic reactions or fail to catalyze them. The experimental results indicate an increase in temperature will increase reaction

Elena Chen CH 221-227 November 3rd, 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle, copper was present in different forms. First reaction involves reaction between the copper and nitric acid, and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into
