Aluminium is extracted from bauxite by the electrolysis of aluminium oxide dissolved in cryolite. Now answer the following question:
Write the equation for the action of heat on aluminium hydroxide.

Explanation

To write the equation for the action of heat on aluminium hydroxide, we need to follow these steps:

### Step 1: Identify the reactant
The reactant in this case is aluminium hydroxide, which has the chemical formula Al(OH)₃.

### Step 2: Understand the reaction
When aluminium hydroxide is heated, it decomposes into aluminium oxide and water. The products of this reaction are aluminium oxide (Al₂O₃) and water (H₂O).
