Answer #1

first write the complete equation

3 CaCl2(aq) + 2 Na3PO4(aq) → Ca3(PO4)2(s) + 6 NaCl(aq)

now

write complete ionic equation

3 Ca2+(aq) + 6Cl-(aq) + 6Na+(aq) + 2 PO43-(aq) → Ca3(PO4)2(s) + 6Na+(aq) + 6Cl-(aq)

cancil the same ions which are present in both sides the remaining equation is net ionic equation

3 Ca2+(aq) + 2 PO43-(aq) → Ca3(PO4)2(s)
