Complete and balance the given precipitation reactions, including the physical states of the products as predicted by the solubility rules.
ba(no3)2(aq) + cuso4(aq) -> ba(so4) (s) + cu(no3)2 (aq)

2k3po4 (aq)+ 3mgcl2(aq) > 6kcl (aq) + mg3(po4)2 (s)

i typed the two equations above, but sapling marked them wrong.
i really need some with the matching question below, i only get so many attempts on my homework.

then, examine the precipitation reactions to determine whether each of the involved species is oxidized, reduced, or neither.

no3-, so43-, k+, po43-, mg2+, cl-, ba2+, cu2+
