Final answer:

The products of the reaction between (NH₄⁺)₃PO₄(aq) and CaCl₂(aq) are calcium phosphate (Ca₃(PO₄)₂) and ammonium chloride (NH₄Cl). The net ionic equation is 3Ca²⁺(aq) + 2PO⁴³⁻(aq) → Ca₃(PO₄)₂(s), showing the formation of the insoluble calcium phosphate precipitate.

Step-by-step explanation:

The question requires predicting the products and writing the molecular and net ionic equations for the reaction between (NH₄⁺)₃PO₄(aq) and CaCl₂(aq). These compounds will undergo a double displacement reaction, yielding calcium phosphate and ammonium chloride. The reaction is:

(NH₄)₃PO₄(aq) + 3CaCl₂(aq) → Ca₃(PO₄)₂(s) + 6NH₄Cl(aq)

The net ionic equation can be determined by removing the spectator ions (NH₄⁺ and Cl⁻) that do not participate in the formation of the insoluble product:

3Ca²⁺(aq) + 2PO⁴³⁻(aq) → Ca₃(PO₄)₂(s)

This shows the actual chemical change involving the calcium and phosphate ions forming the insoluble calcium phosphate precipitate.
