Answer 1

I assume these are aqueous solutions of Ca(OH)2 and NH4Cl but the reaction is more effective with aqueous Ca(OH)2 and solid NH4Cl.
molecular equation is:
2NH4Cl(aq) + Ca(OH)2(aq) ==> 2NH3(g) + 2H2O(l) + CaCl2(aq)
ionic equation is:
2NH4^+ + 2Cl^-(aq) + Ca^2+(aq) + 2OH^-(aq) ==> 2NH3(g) + 2H2O(l) + Ca^+(aq) + 2Cl^-(aq)
net ionic equation is:
2NH4^+(aq) + 2OH^-(aq) ==> 2NH3(g) + 2H2O(l)
