Balance the following chemical equations :
`Al(OH)_(3)overset(Delta)toAl_(2)O_(3)+H_(2)O`

Explanation

To balance the chemical equation `Al(OH)₃ → Al₂O₃ + H₂O`, we will follow a systematic approach using the hit and trial method. Here are the step-by-step details:

### Step 1: Write the unbalanced equation
The unbalanced equation is:
\[ \text{Al(OH)}_3 \rightarrow \text{Al}_2\text{O}_3 + \text{H}_2\text{O} \]

### Step 2: Count the number of atoms of each element on both sides
