Chapter 7, Problem 48QAP

Interpretation Introduction

Interpretation:

For the reaction; $2\text{N}\text{a}(s)+{\text{O}}_2(g)\to \text{N}{\text{a}}_2{\text{O}}_2(s)$

To determine how electrons are gain and lost in the above reaction.

Concept Introduction:

The most common driving forces which create product in chemical reactions are as follows:

1. Formation of a solid.
2. Formation of water.
3. Transfer of electrons.
4. Formation of gas.

Oxidation-reduction reaction is known as redox reaction. In these types of reaction one reactant is oxidized and another is reduced.

Oxidation: Oxidation is a process in which either 1 or all following changes occurs:

1. Gaining of oxygen atoms

2. Increasing oxidation number

3. Loss of hydrogen atom.

4. Loss of electrons.

Reduction: Reduction is a process in which either 1 or all following changes occurs:

1. Loss of oxygen atoms

2. Decreasing oxidation number

3. Gaining of hydrogen atom.

4. Gaining of electrons.
