Chapter 7, Problem 44QAP

Interpretation Introduction

Interpretation:

To describe the transfer of electron for both the aluminium and iron in the reaction: $2\text{A}\text{l}(s)+\text{F}{\text{e}}_2{\text{O}}_3(s)\to 2\text{F}\text{e}(s)+\text{A}{\text{l}}_2{\text{O}}_3(s)$.

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.
