#a.)# #NaOH(aq) + HCl(aq) rarr NaCl(aq) + H_2O(l)#

And the net ionic equation is simply the protonolysis rxn:

#HO^(-) + H^(+) rarr H_2O(l)#, alternatively,

#HO^(-) + H_3O^(+) rarr 2H_2O(l)#

#b.)Pb(OAc)_2(aq) + K_2SO_4(aq) rarr PbSO_4(s)darr + 2K^(+)""^(-)OAc(aq)#

And the net ionic equation:

#Pb^(2+) + SO_4^(2-) rarr PbSO_4(s)darr#

#c.)FeSO_4(aq) + (NH_4)_2S(aq) rarr FeS(s)darr + (NH_4)_2S(aq)#

And the net ionic equation:

#Fe^(2+) + S^(2-) rarr FeS(s)darr#

#d.)NaCl(aq) + KOH(aq) rightleftharpoons NaOH(aq) + KCl(aq)#

For this last, there is NO macroscopic chemical change.
