Explanation / Answer
a) Ammonium Carbonate( (NH4)2CO3) is formed which is a strong electrolyte and completly dissociate in to NH4+ and CO3^2- ions. So , the conductivity of the mixed solution highly increased
b) 2NH4OH(aq) + H2CO3(aq) -------> (NH4)2CO3(aq) + H2O(l)
c) 2NH4OH(aq) + H2CO3(aq) -------> 2NH4+(aq) + CO3^2-(aq) + H2O(l)
