Answer:

3

Explanation:

Al + CuSO₄ → Al₂(SO₄)₃ + Cu

two aluminum atoms in products. put 2 in front of Al in reactants.

2 Al + CuSO₄ → Al₂(SO₄)₃ + Cu

three sulfur atoms and twelve oxygen atoms in products. put 3 in front of CuSO₄ in reactants.

2 Al + 3 CuSO₄ → Al₂(SO₄)₃ + Cu

three copper atoms in reactants. put 3 in front of Cu in products.

2 Al + 3 CuSO₄ → Al₂(SO₄)₃ + 3 Cu

The equation is balanced. Hope that helps.
