YOUR NAME: Erin Alston‚ Kennedy Stuart‚ Amber Lamb and Stephonya Williams EXPERIMENT TITLE: Oxidation: Cyclohexanone from Cyclohexanol by Hypochlorite Oxidation and Adipic Acid from Cyclohexanone DATE: 4/18/2014 INTRODUCTION: In experiment 4‚ alcohol is oxidized to a ketone with household bleach. The product is then isolated by steam distillation and is extracted into the distillate with ether. After the removal of ether‚ it leaves the product cyclohexanone. In experiment 6‚ cyclohexanone is

Name: Date of experiment: 04/02/12 Date of report: 04/03/12 Title: Oxidation – Reduction Activity Series Purpose: To determine relative oxidizing and reducing strengths of a series of metals and ions. Oxidation and reduction reaction occur simultaneously side by side. A reduction reaction occurs only if an oxidation reaction occurs and vise-versa. Electrons are given in oxidation while in reduction electrons are gained. Oxidizing agent is a chemical substance which has a large tendency to

1. Mechanism of oxidation process In an oxidation process of silicon that usually takes place at very high temperature (thermal oxidation)‚ silicon (Si) reacts with either water vapor (H20) or oxygen (O2) to form silicon dioxide‚SiO2 on the silicon surface. The reaction is represented by following equations: Dry oxidation: Si + O2 → SiO2 Wet oxidation: Si + 2H2O → SiO2 + 2H2 The oxidation process can be implemented through diffusion

potassium permanganate solution was titrated thrice to give clear Mn2+ with an analyte of acidified FeSO4 until all the Fe2+ in the solution was oxidized to Fe3+. The color of the MnO4-/Mn2+ was used as the indicator for the titration. A balanced oxidation-reduction‚ the molarity/normality of the standards potassium permanganate‚ and the volume of potassium permanganate used allowed the determination of the concentration of the FeSO4. Equipment and Chemicals: Chemicals: * Iron (II) ammonium sulfate

“The Best Way to Prevent Overdue Accounts” Most businesses have to deal with an overdue or unpaid account at some point or another. The best way to avoid collection hassles is to take preventive measures up front to ensure that accounts don’t become delinquent. Below are some steps you can take to help improve your receivables turnaround. Don’t grant credit. It’s not always possible or practical‚ but some companies can be run without offering credit. Require cash or certified checks/money orders

Skip to next paragraph The Best Ways to Prevent Overdue Accounts First step in preventing overdue accounts is to analyze the potential customer’s credit report before you extend them credit. The reports show historical payment data and a rating that demonstrates how likely they are to pay their bills. While you don’t want to destroy any future or existing business relationships by laying down strict payment terms‚ you must enforce these terms to avoid future cash flow problems. Closely monitor
