उत्तर
Magnesium liberates hydrogen gas on reacting with hot boiling water.
Explanation:
When magnesium metal (Mg) reacts with hot boiling water, it undergoes a chemical reaction to produce magnesium hydroxide and hydrogen gas. While magnesium reacts very slowly with cold water, the increased thermal energy of boiling water significantly accelerates the reaction rate. The balanced chemical equation for this process is:
\[\ce{Mg_{(s)} + 2H2O_{(l)} -> Mg(OH)2_{(aq)} + H2_{(g)}}\]
