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

DATE PERFORMED: JULY 20‚ 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment‚ this spectrophotometry was used to determine the equilibrium constant‚ Keq‚ of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed‚ the concentration of the colored FeSCN2+ solution was also quantitatively

The Equilibrium Constant of an Ester Hydrolysis Reaction Julia Stanley CHM 152 LL Dr. Asmita Kane Budruk Goal of the lab: The purpose of this laboratory is to determine the equilibrium constant‚ Kc‚ for the acid-catalyzed reaction between an unknown ester and water to produce an unknown alcohol and an unknown carboxylic acid. I was using Unknown Ester #3 with a density of 0.9342 and Molar Mass of 74.08 g/mol; alcohol with density 0.7914 and Molar Mass 32.04 g/mol. Chemical

Premium Management Organization Leadership
Groups can be defined by either informal groups‚ or formal groups. Formal groups A formal group is set by an official authority or leader designed to complete a specific task or purpose and is strictly regulated by the organisations rules and practices. In a formal group responsibility of an outcome of a task is set usually to the leader‚ discipline and reward is mainly handed down to the leader via the organisation. A formal group is coordinated by activities shared between a number of people

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

ANSWER KEY 1. A mixture of 0.10 mol of NO‚ 0.050 mol of H2 and 0.10 mol of H2O is placed in a 1.0L flask and allowed to reach equilibrium as shown below: ˆˆ† 2 NO (g) + 2 H2 (g) ‡ˆˆ N2 (g) + 2 H2O (g) At equilibrium [NO] = 0.062 M. Calculate the equilibrium constant‚ Kc‚ for this reaction. ˆˆ† 2 NO + 2 H2 (g) ‡ˆˆ N2 (g) + 2 H2O (g) Initial D Equilibrium K C = 0.10 M – 0.038 0.062 0.050 M – 0.038 0.012 0 + 0.019 0.019 0.10 M + 0.038 0.138 2 2 [N 2 ][H 2 O]
