Write balanced chemical equations for the preparation of the following gases using dilute sulphuric acid as one of the reactants:
Sulphur dioxide.

Explanation

To prepare sulfur dioxide (SO₂) using dilute sulfuric acid (H₂SO₄) as one of the reactants, we can react sodium sulfide (Na₂S) with dilute sulfuric acid. Here’s the step-by-step solution to write the balanced chemical equation:

### Step 1: Identify the Reactants
The reactants for this reaction are:
- Sodium sulfide (Na₂S)
- Dilute sulfuric acid (H₂SO₄)

### Step 2: Write the Unbalanced Equation
