Explanation / Answer

Magnesium undergoes the following reaction with hydrochloric acid represented by the chemical equation:

Mg(s) + 2 HCl(aq) --> MgCl2(aq) + H2(g)

Magnesium is an active metal. Active metals release Hydrogen when contacted with strong acids, here HCl.

Element : Mg (s)
Ionic Compound : MgCl2

Covalent Compunds: HCl and H2

As indicated above, a chemical reaction occured. The products include Hydrogen gas and a Magnesium Salt.
