Here's how to break down the reaction and write the balanced molecular, complete ionic, and net ionic equations:

1. Reactants and Products

* Reactants:

* Aqueous copper(II) chloride (CuCl₂)

* Aqueous ammonium phosphate ((NH₄)₃PO₄)

* Products:

* Solid copper(II) phosphate (Cu₃(PO₄)₂) - This is the precipitate.

* Aqueous ammonium chloride (NH₄Cl)

2. Balanced Molecular Equation

```

3 CuCl₂(aq) + 2 (NH₄)₃PO₄(aq) → Cu₃(PO₄)₂(s) + 6 NH₄Cl(aq)

```

3. Complete Ionic Equation

This shows all ions present in solution:

```

3 Cu²⁺(aq) + 6 Cl⁻(aq) + 6 NH₄⁺(aq) + 2 PO₄³⁻(aq) → Cu₃(PO₄)₂(s) + 6 NH₄⁺(aq) + 6 Cl⁻(aq)

```

4. Net Ionic Equation

This shows only the ions that participate in the formation of the precipitate:

```

3 Cu²⁺(aq) + 2 PO₄³⁻(aq) → Cu₃(PO₄)₂(s)

```

Explanation:

* Molecular Equation: Shows the complete formulas of all reactants and products.

* Complete Ionic Equation: Breaks down all soluble ionic compounds into their respective ions.

* Net Ionic Equation: Removes spectator ions (ions that appear on both sides of the equation and don't participate in the reaction).

Key Points:

* The precipitate, copper(II) phosphate, is a solid and does not dissociate into ions in solution.

* Ammonium chloride is soluble and remains as ions in solution.
