From the molecular equation, we can se that the net ionic equation is; Pb^2+(aq) + S^2-(aq) -----> PbS(s)
What is a net ionic equation?
The net ionic equation is the equation that involves only the ions that underwent a change in the reaction.
The molecular equation is;
Pb(NO3)2(aq)+Na2S(aq)------->PbS(s)+2NaNO3(aq)
The complete ionic equation is;
Pb^2+(aq) + NO3^-(aq) + 2Na^+(aq) + S^2-(aq) -----> PbS(s)+ 2Na^+(aq) + NO3^-(aq)
The net ionic equation is;
Pb^2+(aq) + S^2-(aq) -----> PbS(s)
