4. 2Pb₃O₄ ------> 6PbO + O₂

5. 2ZnS + 3O₂ -----> 2ZnO + 2SO₂

6. 2H₂SO₄ + S ------> 3SO₂ + 2H₂O

7. 6HNO₃ + S ------> H₂SO₄ + 6NO₂ + 2H₂O

8. MnO₂ + 4HCl -----> MnCl₂ + 2H₂O + Cl₂

9. Pb₃O₄ + 8HCl -----> 3PbCl₂ + 4H₂O + Cl₂

10. Ca(HCO₃)₂ + 2HNO₃ -----> Ca(NO₃)₂ + 2H₂O + 2CO₂

11. 2Al + 2NaOH + 2H₂O ----> 2NaAlO₂ + 3H₂
