1) Cu + 2HCl = CuCl₂ + H₂

2) Fe₂O₃ + 6HCl = 2FeCl₃ + 3H₂O

3) AgNO₃ + HCl = AgCl + HNO₃

4) CuS + 2HNO₃ = Cu(NO₃)₂ + H₂S

5) CaCO₃ + 2HNO₃ = Ca(NO₃)₂ + H₂CO₃

6) 2Al + 3H₂SO₄ = Al₂(SO₄)₃ + 3H₂

1) H₂SO₄ + Zn ≈ ZnSO₄ + H₂

2) MnO + H₂SO₄ = MnSO₄ + H₂O

3) Al₂O₃ + 6HCl = 2AlCl₃ + 3H₂O

4) 2Al + 6HCl = 2AlCl₃ + 3H₂
