Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often

Gravimetric Analysis of CA2+ as CaC2O4.H2O Introduction Weight determination represents one of the most accurate and precise form of measurement carried out in lab analysis. Thus‚ gravimetric analysis provides a great assay of a variety of analytes. Mixtures of compounds in difference phases provide us with one of the simplest methods of separation and mass explorations. Separating a solid mass from a liquid involves the commonplace

Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

Determination is a positive emotion that involves persevering towards a difficult goal in spite of obstacles.[1][2] Determination occurs prior to goal attainment and serves to motivate behavior that will help achieve one’s goal. Empirical research suggests that people consider determination to be an emotion; in other words‚ determination is not just a cognitive state‚ but rather an affective state.[3] In the psychology literature‚ researchers have studied determination under other terms‚ including

Determination In “The Glass Castle” we see many different possibilities pertaining to Maslow’s Hierarchy of Needs. We see the father‚ Rex and one of the daughters‚ Maureen‚ who fall victim to Maslow. Then there’s Jeanette and the mother‚ Rose Mary who have both seemed to achieve self-actualization regardless of their hardships. Traditionally‚ Maslow’s Hierarchy is thought to be achieved by working up from the bottom of the pyramid to get to the top. However‚ in “The Glass Castle” this is not particularly

LAB REPORT # 1 DENSITY DETERMINATION CHEMISTRY 100 – 04 INTRODUCTION: The purpose of this experiment is to find out the density of the unknown solid object by determining the mass and the volume through the experiment. To do this we will be get the mass of the object and determine the volume of the object by placing it into a liquid. Then we will divide mass by volume and get its density. PROCEDURE: 1) Obtain a solid metal 2) Weigh the dry sample carefully to
