does the magnesium dissolve?

Magnesium reacts to form magnesium chloride and hydrogen gas according to:
Mg + 2 HCl --> MgCl2 + H2
Since there is water present (the HCl solution contains water) the MgCl2 will be in solution.

Burning magnesium produces magnesium oxide. This oxide hydrates to the hydroxide on contact with water or moist air. On contact with hydrochloric acid, magnesium chloride is formed along with a small amount of water: Mg (s) + O2 (g) ---> MgO (s) MgO (s) + H2O (l) ---> Mg(OH)2 (s) Mg(OH)2 (aq) + 2HCl (aq) ---> MgCl2 (aq) + 2H2O (aq)

This is a redox reaction - magnesium is oxidised and the acid is reduced.
Hydrogen gas and magnesium chloride are the products of this reaction.

The follow reaction occurs
Mg(s) + HCl ----> MgCl2 (aq) + H2(gas)
