Record the equation for the reaction for Mg + NiNo3

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.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
