#### Work Step by Step

a) $2\ NaOH(aq)+FeCl_2(aq)\rightarrow Fe(OH)_2(s)+2\ NaCl(aq)$ Net ionic: $2\ OH^-(aq)+Fe^{2+}(aq)\rightarrow Fe(OH)_2(s)$ b) $Na_2CO_3(aq)+BaCl_2(aq)\rightarrow BaCO_3(s)+2\ NaCl(aq)$ Net ionic: $CO_3^{2-}(aq)+Ba^{2+}(aq)\rightarrow BaCO_3(s)$ c) $3\ NH_3(aq)+H_3PO_4(aq)\rightarrow (NH_4)_3PO_4(aq)$ Net ionic: $NH_3(aq)+H_3O^{+}(aq) \rightarrow NH_4^+(aq)+H_2O(l)$
