Give reasons for the following:
The reaction of iron (III) oxide `[Fe_(2)O_(3)]` with heated aluminium is used to join cracked machine parts.

Explanation

To understand why the reaction of iron (III) oxide \([Fe_{2}O_{3}]\) with heated aluminum is used to join cracked machine parts, we can break down the explanation into the following steps:

### Step 1: Understanding the Reaction
The reaction between iron (III) oxide \([Fe_{2}O_{3}]\) and aluminum is known as the thermite reaction. This is a highly exothermic reaction, meaning it releases a significant amount of heat.

### Step 2: The Chemical Equation
The thermite reaction can be represented by the following chemical equation:
\[
