Answer:

1) CuO + 2HCl --> CuCl2 + H2O

2) Cu(OH)2 + H2SO4 --> CuSO4 + 2H2O

3) Na + OH --> NaOH

4) HCl + H2O --> H3O + Cl

5) HNO3 + H2O >< H3O + NO3       [>< is reversible reaction]

6) H2SO4 + 2H2O >< 2H3O + SO4

7) NH4 + OH >< NH4OH

8) H2SO4 + H2O >< H3O + HSO4

9) HSO4  + H2O >< H3O + SO4

10) Ca + 2OH >< Ca(OH)2

11) Cu + 2OH >< Cu(OH)2

12) H3PO4 + H20 >< H3O + H2PO4

13) H2PO4 + H2O >< H3O + HPO4

14) HPO4 + H2O  >< H3O + PO4

15) H3PO4 + 3H2O >< 3H3O + PO4

16) NaOH + H2SO4 --> NaHSO4 + H2O

17) 2NaOH + H2SO4 --> Na2SO4 + 2H2O

18) NaOH + H3PO4 --> NaH2PO4 + H2O        

19) 2NaOH + H3PO4 --> Na2HPO4 + 2H2O  

20) 3NaOH + H3PO4 --> Na3PO4 + 3H2O
