What type of chemical reaction is Mg + H2SO4-->MgSO4 + H2?

Question

What type of chemical reaction is Mg + H2SO4-->MgSO4 + H2?

Answer 1

Mg is oxidized to Mg²⁺ whilst H⁺ is reduced to H₂. (Oxidation reduction reaction)

Answer 2

This reaction is a single-replacement reaction.

 

They have the general formula of

 

A + BC => AC + B

 

Mg + H₂SO₄ => MgSO₄ + H₂

 

This matches the general formula, therefore this is a single-replacement reaction.
