Look at the chemical reaction below. Magnesium + hydrochloric acid → magnesium chloride + hydrogen

Mg + 2HCl → MgCl2 + H2

In this reaction:
Magnesium (Mg) is a

Hydrogen (H2) is a

magnesium chloride (MgCl2) is a

hydrochloric acid (HCl) is a

In the reaction:

Magnesium (Mg) is a solid metal reactant reducing agent

Hydrogen is a gaseous product (oxidation product)

Magnesium chloride (MgCl₂) is an aqueous product (reduction product)

Hydrochloric acid (HCl) is an aqueous acidic reactant oxidizing agent

Explanation:

The reaction Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂ (g)

The above reaction can be used to demonstrate the reaction characteristic between metals and acid involving the liberation of hydrogen gas

In the reaction:

Magnesium (Mg) is a solid metal reactant

Hydrogen is a gaseous product

Magnesium chloride (MgCl₂) is an aqueous product

Hydrochloric acid (HCl) is an aqueous acidic reactant
