1. For the following reactions, determine the products when two solutions are mixed. Use the solubility rules to predict whether a precipitate would form. If no reaction occurs, write "NR”. Be sure to balance your reaction and include all states of matter. The first one has been done for you. a) 3 Ba(NO3)2 (aq) + Al2(SO4)3 (aq) → 2 AI(NO3)3 (aq) + 3 BaSO4 (s) b) LINO3(aq) + Mg(C2H302)2 (aq) → c) NiSO4 (aq) + K3PO4 (aq) → d) Na2S...

in the table below, predict which of the following reactant
combinations will produce precipitates and write all the products
that form (including states of matters- l, s, aq, g;
write "ss" if it is slightly soluble). Useful
information is also below.
