Answer:

Mg(s) + 2H⁺ → Mg²⁺(aq) + H₂.

Explanation:

  • To obtain the overall reaction, we sum the two half-reactions and omit the similar species in the reactants and products sides.
  • We have two reactions:

oxidation reaction:

Mg(s) → Mg²⁺(aq) + 2e.

Reduction reaction:

2H⁺ + 2e → H₂.

  • So, we add the two half-reactios and obtain the overall reaction:

Mg(s) + 2H⁺ → Mg²⁺(aq) + H₂.
