Answer 2

I'll provide you with balanced chemical equations for each of the reactions you've mentioned:

1. CuO + H2SO4 → CuSO4 + H2O

2. K2O + 2HNO3 → 2KNO3 + H2O

3. Na2O + SO2 → Na2SO3

4. Na2O + H2O → 2NaOH

5. N2O5 + CaO → 2Ca(NO3)2

6. CO2 + H2O → H2CO3

7. Fe2O3 + 6HCl → 2FeCl3 + 3H2O

8. CaO + CO2 → CaCO3

9. MgO + 2H3PO4 → Mg3(PO4)2 + 3H2O

10. SO3 + H2O → H2SO4
