Answer 2

Balancing Chemical Equations

1. Balancing the Chemical Equations: - 1. C + O₂ → CO - 2. SO₂ + O₂ → SO₃ - 3. NaNO₃ → NaNO₂ + O₂ - 4. Al₂O₃ + HI → AlI₃ + H₂O - 5. NH₃ + O₂ → NO + H₂O - 6. Al(OH)₃ → Al₂O₃ + H₂O - 7. Cu(NO₃)₂ → CuO + NO₂ + O₂ - 8. C₂H₄ + O₂ → CO₂ + H₂O - 9. CO + O₂ → CO₂ - 10. P + O₂ → P₂O₅

2. Balanced Chemical Equations: - 1. C + O₂ → CO - 2. 2SO₂ + O₂ → 2SO₃ - 3. 2NaNO₃ → 2NaNO₂ + O₂ - 4. 2Al₂O₃ + 6HI → 2AlI₃ + 3H₂O - 5. 4NH₃ + 5O₂ → 4NO + 6H₂O - 6. 2Al(OH)₃ → Al₂O₃ + 3H₂O - 7. 2Cu(NO₃)₂ → 2CuO + 4NO₂ + O₂ - 8. C₂H₄ + 3O₂ → 2CO₂ + 2H₂O - 9. 2CO + O₂ → 2CO₂ - 10. 4P + 5O₂ → 2P₂O₅
