For the following reactions, write the balanced formula equation, complete ionic equation, and net ionic equation. (Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer. If no reaction occurs, type "NONE" in the answer box for that reaction.)
BaCl2(aq) + Na2SO4(aq)
AgNO3(aq) + Na3PO4(aq)
Pb(NO3)2(aq) + KCl(aq)
