Yes, copper sulfate can be prepared from metal and dilute sulfuric acid. The reaction between copper metal and dilute sulfuric acid can be represented by the following equation:

$$Cu(s) + H_2SO_4 (aq) → CuSO_4 (aq) + H_2 (g)$$

In this reaction, copper metal reacts with sulfuric acid to form copper sulfate and hydrogen gas. The reaction proceeds as follows:

1. Copper metal atoms lose two electrons each to form copper ions (Cu2+).

2. The hydrogen ions (H+) in the sulfuric acid combine with the electrons lost by the copper atoms to form hydrogen gas (H2).

3. The copper ions and sulfate ions (SO42-) in the solution combine to form copper sulfate.

The reaction is exothermic, meaning that it releases heat. The rate of the reaction can be increased by heating the mixture or by adding a catalyst such as iron(III) sulfate.
