isomers of a typical coordination compound. INTRODUCTION: Isomerism played a central role to establish the basic concept in coordination chemistry while reaction kinetics of coordination compound is known as the area of continuing intense research activity. The mechanism of the reactions of coordination compounds relevance to enzyme reactions where the active site is being involve in coordination to a metal ion. PROCEDURE: (A) Preparation of Trans-Dichlorobis(ethylenediamine)cobalt(III) chloride

percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask was cooled in a beaker in the water of room temperature. The solid was formed in the mixture and the flask was shaken until it dissolved. The flash was rinsed with 15 mL dichloromethane and it was

PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

Hardware Replacement Project IT/205 Randy Atkins December 16‚ 2012 Hardware Replacement Project The IT department wants to replace their old CRM with a new CRM solution. The only problem is that their existing hardware is old and out of date and will not support the new CRM. I was brought in to not only recognize the issue but to determine what equipment will be needed and help install the equipment. This needed to be done before the new CRM system can be installed and implemented. Before

transfer 0.8 ml of this solution and the reaction was allowed to proceed until the solution turns brown and cloudy. The conical vial was then rinsed with 2 ml of anhydrous ether to get any remaining solution into the reaction vessel. Simultaneously‚ 1.09 g of benzophenone and 2ml of anhydrous ether were added to a 3ml conical vial and gently stirred. The reaction vessel was taken off of the hot plate and allowed to cool. The benzophenone was then added to the reaction mixture while stirring vigorously.

Experiment 4: Qualitative Analysis of Cations and Precipitation Reactions The overall goal of experiment four was to determine the identity of unknown cations presented to the student. But in order to know the identity of these unknowns‚ in part 1‚ Ag+‚ Pb+‚ and Hg22+ were presented to the student in aqueous solutions and then precipitated through experimentation. In part 2‚ the same procedure was enacted to determine which substances precipitated through qualitative analysis. Solubility rules
