Answer:

Mg(s) + 2H⁺(aq) ⟶ Mg²⁺(aq) + H₂(g)

Explanation:

A net ionic equation shows all the ionic substances as ions and shows the correct state of each substance.

B. is wrong. HCl ionizes in aqueous solution into H⁺ and Cl⁻.

C. is wrong. Mg²⁺ is not a solid. It is an aqueous ion.

D. is wrong. The equation needs 2H⁺(aq) to be balanced.
