You're asking for the molecular, total ionic, and net ionic equations for the reaction between copper(II) nitrate (Cu(NO₃)₂) and zinc (Zn). Let's break it down:

1. Molecular Equation

* Reactants: Copper(II) nitrate (Cu(NO₃)₂) and zinc (Zn)

* Products: Copper (Cu) and zinc nitrate (Zn(NO₃)₂)

The balanced molecular equation is:

Cu(NO₃)₂ (aq) + Zn (s) → Cu (s) + Zn(NO₃)₂ (aq)

2. Total Ionic Equation

This equation shows all the ions present in solution:

* Cu(NO₃)₂ (aq) → Cu²⁺ (aq) + 2 NO₃⁻ (aq)

* Zn(NO₃)₂ (aq) → Zn²⁺ (aq) + 2 NO₃⁻ (aq)

The total ionic equation is:

Cu²⁺ (aq) + 2 NO₃⁻ (aq) + Zn (s) → Cu (s) + Zn²⁺ (aq) + 2 NO₃⁻ (aq)

3. Net Ionic Equation

This equation shows only the species that directly participate in the reaction:

* Cancel out the spectator ions (NO₃⁻) which appear on both sides.

The net ionic equation is:

Cu²⁺ (aq) + Zn (s) → Cu (s) + Zn²⁺ (aq)

Explanation:

* The reaction is a single displacement reaction where zinc, being more reactive than copper, displaces copper from its nitrate salt solution.

* The net ionic equation represents the actual chemical change that occurs, showing the transfer of electrons from zinc to copper ions.
