Question

Based on the solubility guidelines predict the outcome of the following reactions. If you think a precipitation reaction will occur, balance the reaction and write the complete and net ionic equations of the reaction. ( you must show states of the reactants and products)

Pb(NO3)2 (aq) + (NH4)S (aq) =

FeSO4 (aq) + AgNO3 (aq) =
