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

Explanation

To prepare carbon dioxide (CO₂) using dilute sulfuric acid (H₂SO₄) as one of the reactants, we can follow these steps:

### Step 1: Identify the Reactants
We know that dilute sulfuric acid (H₂SO₄) will be one of the reactants. To produce carbon dioxide, we need a source of carbon. Carbonates or bicarbonates are suitable compounds for this purpose.

### Step 2: Choose a Carbonate
We can use sodium carbonate (Na₂CO₃) as our carbonate source.
