Ashley Silva Lab 7: Three Stooges in Chemical Reactions Objective: The purpose of this lab is to experimentally determine the equilibrium constant‚ Kc ‚ for the following chemical reaction: Fe3+ (aq) + SCN-(aq) ↔FeSCN2+(aq) Background Information: A system is at equilibrium when the rate of the forward reaction is the same as the rate of the reverse reaction. There is no change in concentration for the reactants or products at chemical equilibrium. When the system is disturbed there

ERYTHROCYTE SEDIMENTATION RATE | -AND ITS VARIATION | | ABSTRACT: The Erythrocyte Sedimentation Rate (ESR)‚ also branded as sedimentation rate or Biernacki Reaction‚ is the rate at which red blood cells sediment in a time of 1 hour. To execute the test‚ anti-coagulated blood is positioned in an erect tube‚ known as a Westergren tube‚ and the rate at which the red blood cells fall is calculated and accounted in millimeters per hour (mm/h)

purpose of this experiment was to prepare the Grignard reagent methylmagnesium iodide and react it with benzoin to form the 3o alcohol 1‚2-diphenyl-1‚2-propanediol‚ through an addition reaction pathway. Introduction: Grignard reagents are alkyl or aryl-magnesium halides that act as the nucleophile in Grignard reactions‚ where ketones are reacted with the reagent‚ then treated with acid to produce an alcohol. In the case of this experiment‚ methylmagnesium iodide was created from methyl iodide and

Concentration‚ Along with Varying Temperature and pH-Balanced Environments on the Enzyme-Catalyzed Reaction of pNPP Abstract: Introduction: Many of the chemical reactions‚ which take place in in living things are controlled by enzymes. In such cases‚ the enzyme is a protein in the cell which lowers the activation energy of a catalyzed reaction‚ which serves to increase the rate of the reaction. Alkaline phosphatase is made throughout the body. Its function is to remove phosphate groups

temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient energy for the substrates to move at a fast rate‚ hence decreased the number of collisions with the enzymes. However

Exchange rate development in Ethiopia Monetary Development The legal tender currency of Ethiopia was issued on 23 July 1945 by defining the monetary unit as the Ethiopia dollar (E$) with a value of 5.52 grains (equivalent to 0.355745 grams) of fine gold. The linkage with fine gold was in accord with the monetary system established by the Bretton Woods Agreement of 1944. For the five years following the proclamation of the national currency (1945–1950)‚ money supply of the country was determined

vol. 2‚ 2012 TARGETING OF KEY INTEREST RATE AS A SOURCE OF CRISIS YANA SOKOLOVA St. Petersburg State University‚ Faculty of Economics‚ Russia Abstract In response to the world economic crisis of 2008 the authorities of many countries have launched policies of interest rate reduction through large-scale asset purchases on the open key rate targeting. The author explains how changes of the federal funds rate increased bank interest rate risk and provoked the recession of 2007-2009
