Magnesium Reacting with Steam

Mg + H₂O → MgO + H₂

نظرة عامة

Magnesium reacts with steam to produce magnesium oxide and hydrogen gas. The reaction is vigorous and highly exothermic. Hot magnesium burns with an intense white flame even in steam, making this a dramatic and instructive demonstration of the high reactivity of magnesium.
