Answer:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
Explanation:
Step 1: Write out unbalanced reaction
Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Step 2: Balance
We need the same number of SO₄²⁻ on each side
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Now we need the same amount of H⁺ on each side
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
