Problem

Aqueous calcium acetate is mixed with aqueous ammonium phosphate. Which of the following is the correct net ionic equation for the reaction that occurs? a) Ca2+(aq)+PO43−(aq)  ⟶  CaPO4(s)\text{Ca}^{2+}(aq)+\text{PO}_{4}^{3-}(aq)\;\longrightarrow\;\text{CaPO}_{4}(s) b) 3 Ca2+(aq)+2 PO43−(aq)  ⟶  Ca3(PO4)2(s)3\,\text{Ca}^{2+}(aq)+2\,\text{PO}_{4}^{3-}(aq)\;\longrightarrow\;\text{Ca}_{3}(\text{PO}_{4})_{2}(s) c) Ca(C2H3O2)2(aq)+(NH4)3PO4(aq)  ⟶  Ca3(PO4)2(s)+3 NH4C2H3O2(aq)\text{Ca}(\text{C}_{2}\text{H}_{3}\text{O}_{2})_{2}(aq)+(\text{NH}_{4})_{3}\text{PO}_{4}(aq)\;\longrightarrow\;\text{Ca}_{3}(\text{PO}_{4})_{2}(s)+3\,\text{NH}_{4}\text{C}_{2}\text{H}_{3}\text{O}_{2}(aq) d) 2 Ca2+(aq)+3 PO43−(aq)  ⟶  Ca2(PO4)3(s)2\,\text{Ca}^{2+}(aq)+3\,\text{PO}_{4}^{3-}(aq)\;\longrightarrow\;\text{Ca}_{2}(\text{PO}_{4})_{3}(s)
