Here's the reaction:

CuO (s) + H₂SO₄ (aq) → CuSO₄ (aq) + H₂O (l)

* CuO is a solid, dark brown powder.

* H₂SO₄ is sulfuric acid, a strong acid.

* CuSO₄ is copper sulfate, a blue crystalline solid.

* H₂O is water.

Explanation:

When copper(II) oxide reacts with sulfuric acid, the oxide dissolves, and copper sulfate is formed in solution. The reaction is an acid-base reaction, where the oxide acts as a base and sulfuric acid acts as an acid.

It's important to note that while other insoluble bases like copper hydroxide (Cu(OH)₂) can react with sulfuric acid to form copper sulfate, copper(II) oxide is the most common and practical choice.
