Write chemical equations for the laboratory preparation of the following salts using sulphuric acid:
Sodium sulphate from sodium carbonate

Explanation

To prepare sodium sulfate (Na2SO4) from sodium carbonate (Na2CO3) using sulfuric acid (H2SO4), we can follow these steps:

### Step 1: Write the Reactants
We start with sodium carbonate (Na2CO3) and sulfuric acid (H2SO4) as our reactants.

### Step 2: Identify the Products
When sodium carbonate reacts with sulfuric acid, the products formed are sodium sulfate (Na2SO4), carbon dioxide (CO2), and water (H2O).
