Write chemical equation for the preparation of `CuSO_(4)*5H_(2)O` in the laboratory.

Explanation

To prepare copper(II) sulfate pentahydrate (CuSO₄·5H₂O) in the laboratory, we can follow these steps:

### Step 1: React Copper with Concentrated Sulfuric Acid
The first step involves the reaction of copper (Cu) with concentrated sulfuric acid (H₂SO₄). The balanced chemical equation for this reaction is:

\[ \text{Cu (s)} + \text{H}_2\text{SO}_4 \text{(aq)} \rightarrow \text{CuSO}_4 \text{(aq)} + \text{H}_2 \text{(g)} \]
