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

General Chemistry II Determining of the equilibrium constant for the formation of FeSCN2+ Introduction The objective of this experiment was to determine the equilibrium concentration and then determine Kc. A dilution calculation was formed to determine the concentration of SCN- and Fe(SCN)2+. Each cuvette was filled to the same volume and can be seen in table 1. Then the absorbances were recorded from each cuvette and can be seen in table 1. A Beer’s law plot was made from the data that was recorded

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

Development of the Boeing 787 Dreamliner Introduction In 2003‚ Boeing launched a project to build a new airframe that had the original designation of 7E7 Dreamliner. In January 2005‚ the aircraft was redesigned the 787 Dreamliner. Boeing’s intent was to utilize new technology and procurement processes to build two versions of the aircraft. The 787-8 was designed to carry 210 to 250 passengers on routes of 7‚650 to 8‚200 nautical miles and the stretch version (787-9) was designed to transport

Boeing engineers union rejects contract offer Negotiations between Boeing and SPEEA began April 19. In the weeks since then‚ the company and union have continued to meet on a regular basis‚ focusing on specific issues each week. One SPEEA contract covers 23‚000 professional engineers in Puget Sound‚ Portland and Ogden‚ Utah; the other covers technical workers in Puget Sound and Portland. The two contracts are similar in many respects but not identical. Main issues included wage pools‚ medical

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
Premium Evolution Natural selection Biology
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
