Week 13 Chem 143, Prof Cracolice Chapter 70: How Are Electron Transfer Reaction Equations Written 4/18/16 70.1 How are Electron Transfer Reaction Equations Written 1. Balance Oxidation numbers a. Identify the elements that are being oxidized and reduced base on the equation. Then write half reactions for the oxidation and reduction reactions b. Balance element that is being oxidized or reduced. Make sure there are the same number on each side before you do anything with oxidation numbers c. Balance the elements other than hydrogen or oxygen. These elements are the ones that don’t have a variation on oxidation number. This keeps the equation balanced d. Determine how the oxidation num
