Magnesium reacts with hydrochloric acid to produce magnesium chloride and hydrogen gas. The reactants in this reaction are 1 molecule of Magnesium Mg and 2 molecules of Hydrochloric acid.

i.e.

A chemical reaction is a chemical process in which one or more elements or compounds combine together to react under some conditions (such as varying degrees of temperature and pressure) to produce different products.

In the given reaction, 1 molecule of Magnesium Mg and 2 molecules of Hydrochloric acid react together to produce 1 molecule of Magnesium chloride and 1 molecule of hydrogen gas.

i.e.

            Mg + 2 HCl → MgCl₂ + H₂

             Reactants         Products

Therefore, we can conclude that the reactants in this reaction are Magnesium and Hydrochloric acid.
