✔ 最佳答案

1. 2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(l)

2. 2Cu(NO3)2(s) → 2CuO(s) + 4NO2(g) + O2(g)

3. 2KClO3(s) → 2KCl(s) + 3O2(g)

4. 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(l)

5. 3CuOs) + 2NH3(g) → 3Cu(s) + N2(g) + 3H2O(l)

6. 4FeS2(s) + 11O2(g) → 2Fe2O3(s) + 8SO2(g)

7. 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(l)

8. Mg3N2(s) + 3H2O(l) → 3MgO(s) + 2NH3(g)

9. 2Al(s) + 3Fe^2+(aq) → 2Al^3+(aq) + 3Fe(s)

(In Questions 1, 4, 5 and 7, the product H2O should be in gaseous state because of the high temperatures.)
