Chemistry 217 Dr.Rudolf Rednose Tues/8am/S-473 Determining the Percent Oxygen in the Air INTRODUCTION: Recent tragedies in coal mines have exemplified the importance for us humans to breathe an adequate amount of oxygen if we are to survive. But what amount of oxygen is adequate? How can we know the amount of oxygen present in what we consider fresh air? The purpose of this experiment was to determine the percent oxygen typically present in air. The conclusion of the test suggested that

Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are

chain respectively. The Krebs cycle uses the two pyruvates produced in glycolysis to make 2 ATPs per glucose and energy. This occurs through the oxidation of a pyruvate‚ wherein one of the three carbons will bond to oxygen and leave the cell as carbon dioxide (CO2)‚ leaving a two-carbon molecule called acetyl coenzyme A.

Primary alcohols undergo oxidation to form carboxylic acids in two stages‚ it forms an aldehyde and then to the acid. In this experiment‚ we are used to prepare benzoic acid from benzene. Potassium permanganate is used this operation as an oxidizing reagent‚ it is used to oxidize the benzoic acid as well as acting as a catalyst for the reaction. Potassium permanganate (KMnO4) is a very strong oxidant which is able to react with many functional groups‚ such as secondary alcohols‚ 1‚2-diols‚ aldehydes

Abstract Chemical reactions can be used to produce electricity and electricity can be used to cause chemical reactions through oxidation-reduction reactions. The first part of the experiment measures the standard electrode potentials of five various half cells against the Cu2+(1M)|Cu half cell. The last three half cells are prepared through electrolysis. The electrode potentials of all reactions are positive which means that they are spontaneous. There is a significant percent difference from the
