Answer:

3CuSO₄ (aq) + 2Al (s) → 3Cu (s) + 2Al₂(SO₄)₃ (aq)

Step-by-step explanation:

The reaction between copper(II) sulfate (CuSO₄) and aluminum (Al) is a redox reaction. In this reaction, aluminum acts as a reducing agent, and copper(II) ions are reduced to copper metal while aluminum is oxidized to form aluminum sulfate.

The balanced chemical equation for this reaction is:

3CuSO₄ (aq) + 2Al (s) → 3Cu (s) + 2Al₂(SO₄)₃ (aq)

This equation ensures that the number of atoms of each element on both sides of the equation is the same, satisfying the law of conservation of mass.
