Mg+HCl

Magnesium (Mg) reacts with hydrochloric acid (HCl) to form magnesium chloride (MgCl2) and hydrogen gas (H2) according to the following balanced chemical equation:

Mg + 2HCl -> MgCl2 + H2

In this reaction, one magnesium atom (Mg) reacts with two hydrochloric acid molecules (2HCl) to produce one molecule of magnesium chloride (MgCl2) and one molecule of hydrogen gas (H2).
