Answer

See answer below.

Work Step by Step

a) Balanced equation $(NH_4)_2CO_3(aq)+Cu(NO_3)_2(aq)\rightarrow CuCO_3(s)+2\ NH_4NO_3(aq)$ Net ionic equation $CO_3^{2-}(aq)+Cu^{2+}(aq)\rightarrow CuCO_3(s)$ b) Balanced equation $Pb(OH)_2(s)+2\ HCl(aq)\rightarrow PbCl_2(s)+2\ H_2O(l)$ Net ionic equation (no spectator ion) $Pb(OH)_2(s)+2\ H_3O^+(aq)+2\ Cl^-\rightarrow PbCl_2(s)+4\ H_2O(l)$ c) Balanced equation $BaCO_3(s)+2\ HCl(aq)\rightarrow BaCl_2(aq)+H_2O(l)+CO_2(g)$ Net ionic equation ($Cl^-$ is the only spectator ion) $BaCO_3(s)+2\ H_3O^+(aq)\rightarrow Ba^{2+}(aq)+3\ H_2O(l)+CO_2(g)$ d)Balanced equation $2\ CH_3CO_2H(aq)+ Ni(OH)_2(s) \rightarrow Ni(CH_3CO_2)(aq)+2\ H_2O(l)$ Net ionic equation (acetate is the only spectator ion) $Ni(OH)_2(s)+2\ H_3O^+(aq)\rightarrow Ni^{2+}(aq)+4\ H_2O(l)$
