Answer 1

1. N2O5 + H2O=> 2HNO3
N2O5 + H2O=> 2H+ + 2NO3-
 2. K20 + H2O=>2KOH
K20 + H2O=>2K+ + OH-
 3. 2NaOH + H2SO3=>Na2SO3 + H2O
2Na+ + 2OH- + 2H+ + SO3 2- =>2Na+ + SO3 2- + H2O
 4. ZnBr2 + 2NaOH=>2NaBr + Zn(OH)2
Zn2+ + 2Br- + 2Na+ + 2OH - =>2Na+ + 2Br- + Zn(OH)2
5. Ba(NO2)2 + 2HCl=> BaCl2 + 2HNO2
Ba2+ + 2NO2- => Ba+2 + 2Cl- + 2HNO2
6. CH3COOH + KOH=>CH3COOK + H2O
7. Na2HPO4+ 2HNO3=>2NaNO3 + H3PO4
2Na+ + HPO4 - + 2H+ + 2NO3- => 2Na+ + 2NO3- + H3PO4
8. NH4Cl + AgNO3=>AgCl + NH4NO3
NH4+ + Cl- + Ag+ NO3 - =>AgCl + NH4+ + NO3-
9. ZnSO4 + NH4OH=>(NH4)2SO4 + Zn(OH)2
Zn+2 + SO4 2-  + 2NH4+ 2OH- =>2NH4 + + SO4  2- + Zn(OH)2
 10. Sn(OH)4 + 2NaOH=>Na2[Sn(OH)6]
Sn(OH)4 + 2Na+ + 2OH- =>Na+ + [Sn(OH)6]2-
 11. 2CH3COOK + H2SO4=>K2SO4 + 2CH3COOH
2CH3COO- + 2K+ + 2H+ + SO4 2-=> 2K+ + SO42- + 2CH3COOH
 12.Fe(NO3)3 + 3NaOH=> Fe(OH)3 + 3NaNO3
Fe3+ + 3NO3 -  + 3Na+ + 3OH- => Fe(OH)3 + 3Na+ + 3NO3 -
