Answer:

Balanced chemical equation:

2Al + 3H₂SO₄  →  Al₂(SO₄)₃ + 3H₂

Explanation:

Chemical equation:

Al + H₂SO₄  →  Al₂(SO₄)₃ + H₂

Balanced chemical equation:

2Al + 3H₂SO₄  →  Al₂(SO₄)₃ + 3H₂

Steps:

Let balance the SO₄ first.

Al + 3H₂SO₄  →  Al₂(SO₄)₃ + H₂

There are three H₂ on left so put the coefficient three on right too.

Al + 3H₂SO₄  →  Al₂(SO₄)₃ + 3H₂

Two Al  on right and one on left so we will put the coefficient two on left.

2Al + 3H₂SO₄  →  Al₂(SO₄)₃ + 3H₂

All atoms are correctly balanced.
