Write the net ionic equation for the precipitation reaction or reaction that occur?

Three solutions are mixed together to form a single solution. One contains 0.2 mol of Pb(CH3COO)2, the second contains 0.1 mol of Na2S , and the third contains 0.1 of CaCl2.

Write the net ionic equations for the precipitation reaction or reactions that occur.

Thanks guys!

Look up solubility rules such as This should tell you that lead sulphide and lead chloride are not very soluble and will precipitate. Something like

2Pb(CH3COO)2(aq) + Na2S + CaCl2 ---> PbS(s) + PbCl2(s) + 2NaCH3COO(aq)

puttting charges in

2Pb2+(CH3COO-)2(aq) + (Na+)2S2- + Ca2+(Cl-)2 ---> PbS(s) + PbCl2(s) + 2Na+CH3COO-(aq)

Separating ions in soluble compounds

2Pb2+(aq) + 2CH3COO-(aq)+ 2Na+(aq) + S2-(aq) + Ca2+(aq) + 2Cl-(aq) ---> PbS(s) + PbCl2(s) + 2Na+(aq) + 2CH3COO-(aq)

Eliminating spectator ions

2Pb2+(aq) + S2-(aq) + 2Cl-(aq) ---> PbS(s) + PbCl2(s)
