Double Displacement, AB + CD = AD + CB
更新1:
what are the spectator ions
更新2:
for this balanced chemical equation
更新3:
6Na+(aq)+2 (PO4)3-(aq) + 3Ca2+(aq) 6Cl-(aq) + 6Cl-(aq) + Ca3(PO)42(s)
Does the reaction occur? what is the reason why?

Yes, the reaction occurs because of the formation of calcium phosphate precipitation.
The total ionic equation is:
6Na⁺(aq) + 2(PO₄)³⁻(aq) + 3Ca²⁺(aq) + 6Cl⁻(aq) → 6Na⁺(aq) + 6Cl⁻(aq) + Ca₃(PO4)₂(s)
The net ionic equation is:
3Ca²⁺(aq) +2(PO₄)³⁻(aq) → Ca₃(PO4)₂(s)
The spectator ions are sodium ion (Na⁺) and chloride ion (Cl⁻) ion.
