Problem

For the reaction shown, write the balanced net ionic equation and state the net total charge on each side to confirm charge balance. 6 NH4+(aq)+2 PO43−(aq)+3 Ca2+(aq)+6 NO3−(aq)  ⟶  Ca3(PO4)2(s)+6 NH4+(aq)+6 NO3−(aq)6\,\text{NH}_{4}^{+}(aq)+2\,\text{PO}_{4}^{3-}(aq)+3\,\text{Ca}^{2+}(aq)+6\,\text{NO}_{3}^{-}(aq)\;\longrightarrow\;\text{Ca}_{3}(\text{PO}_{4})_{2}(s)+6\,\text{NH}_{4}^{+}(aq)+6\,\text{NO}_{3}^{-}(aq)
Intuitive explanation

Net ionic equations strip away spectator ions—the ions that appear unchanged on both sides—to reveal only the species that actually participate in the reaction. Here, you'll identify which ions cancel out completely, then verify your answer by checking that the total charge is identical on both sides. This charge balance is your built-in correctness check.
