Find Net Ionic equation for hydrolysis , Expression for equilibrium constant (Ka or Kb) and Value of (Ka or Kb)

Net Ionic equations I've got

NaC2H3O2 == CH3COO^-+H2O -->CH3COOH+OH^-

Na2CO3 ==== CO3 + 2H2O → H2CO3 + 2-OH
Kb = [H2CO3] [-OH]2 / [CO3].
Kb = 1/Ka1Ka2 = 7.1x10^13

NH4Cl === NH4Cl+H2O --> NH4OH + HCl

ZnCl2 === Zn2+H2O--> ZnO+2H^+

KAl(SO4)2 === Al^+3 + 3OH--> Al(OH)3


I have no idea about the rest.

Thank you!!!
