Which is the correct equation for the reaction of magnesium with hydrochloric acid to produce hydrogen and magnesium chloride? a.mg + 2 hcl → h2 + mgcl2 b.mg + hcl → h + mgcl c.2 mg + 6 hcl → 3 h2 + 2 mgcl2 d.mg + 2 hcl → 2 h + mgcl2 e.mg + 3 hcl → 3 h + mgcl2?

  • Dejanras: Answer is: a. Mg + 2HCl → H₂ + MgCl₂.
    Reduction hald reaction: 2H⁺ + 2e⁻→ H₂.
    Oxidation half reaction: Mg
    ⁰ → Mg²⁺ + 2e⁻.
    In this chemical reaction, magnesium lost two electrons (oxidation, change oxidation number from 0 to +2) and hydrogen gain that two electrons (reduction, change oxidation number from +1 to 0).
