Oxidizing Agents and Aging 7. Balancing Redox Reactions 7. In many chemical reactions, electrons are completely or partially transferred from one atom to another.

These reactions are called oxidation-reduction reactions or redox reactions. This section provides examples of these reactions and introduces the terms oxidation, reduction, oxidizing agent, and reducing agent, which are summarized in Figure 7.

To describe what oxidation numbers are, how they can be determined, and how they can be used to determine 1 whether the reaction is an oxidation-reduction reaction, 2 what is oxidized in an oxidation-reduction reaction, 3 what is reduced in an oxidation-reduction reaction, 4 what the oxidizing agent is in an oxidation-reduction reaction, and 5 what the reducing agent is in an oxidation-reduction reaction.

Oxidation numbers, which are described in this section, provide a tool that allows you to determine the things mentioned in the goal above. Sample Study Sheet 7. Assignment of Oxidation Numbers and Tables 7. The section on our Web site called Balancing Equations for Redox Reaction describes how you can use oxidation numbers.

Balancing Redox Reactions Section 7. To describe different types of chemical reactions. Chemical reactions can be classified into types of similar reactions.

This section describes some of these types: You will learn how to identify each type of reaction from chemical equations. The section also describes how you can write chemical equations for combustion reactions Study Sheet 7.

The attempt to help you visualize chemical changes on the particle level continues with a description of the single-displacement reaction between solid zinc and aqueous copper II sulfate Figure 7.

The animation on our Web site called Single-Displacement Reactions will help you visualize single-displacement reactions.

Single-Displacement Reaction Section 7. To show how oxidation-reduction reactions can be used to create voltaic cells—that is, batteries. This is one of the sections that are spread throughout the text that show you how what you are learning relates to the real world.

In this case, you see how electrons transferred in oxidation-reduction reactions can be made to pass through a wire that separates the reactants, Chapter 7 — Oxidation-Reduction Reactions 87 thus creating a voltaic cell, which is often called a battery.
