Write chemical equations for the laboratory preparation of the following salts using sulphuric acid:
Copper sulphate from copper

Explanation

To prepare copper sulfate (CuSO₄) from copper (Cu) using sulfuric acid (H₂SO₄), we can follow these steps:

### Step 1: Identify the Reactants
The reactants for this reaction are copper (Cu) and sulfuric acid (H₂SO₄).

### Step 2: Write the Unbalanced Chemical Equation
The initial unbalanced chemical equation for the reaction is:
\[ \text{Cu} + \text{H}_2\text{SO}_4 \rightarrow \text{CuSO}_4 + \text{SO}_2 + \text{H}_2\text{O} \]
