This is a true statement. When hydrogen peroxide is mixed with magnesium ribbon, a chemical reaction occurs and hydrogen gas is produced as one of the products. The balanced chemical equation for this reaction is:
2 H2O2 (aq) + 2 Mg (s) → 2 MgO (s) + 2 H2O (l) + H2 (g)
The magnesium reacts with the hydrogen peroxide to produce magnesium oxide and water as well as hydrogen gas. This is known as a displacement reaction, where the more reactive magnesium takes the place of the hydrogen in the hydrogen peroxide molecule, resulting in the formation of hydrogen gas.
