Answer:
Mg⁰(s) + Ni(NO₃)₂(aq) => Mg(NO₃)₂(aq) + NI⁰(s)
Explanation
Molecular Equation: Includes ground state elements and molecular species involved in reaction process.
Mg⁰(s) + Ni(NO₃)₂(aq) => Mg(NO₃)₂(aq) + NI⁰(s)
Ionic Equation: Includes all species associated with rxn process
Mg⁰(s) + Ni²⁺(aq) + 2NO₃⁻ (aq) => Mg²⁺(aq) + 2NO₃⁻(aq) + NI⁰(s)
Net Ionic Equation: Includes only those species that are involved in rxn
Mg⁰(s) + Ni²⁺(aq) => Mg²⁺(aq) + NI⁰(s)
*Nitrate ion (NO₃⁻) is a spectator ion; i.e., does not enter into oxidation-reduction process and is not included in the net ionic equation.
