Magnesium Reacting with Steam
Mg + H2O → MgO + H2
Aperçu
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.

Exemple du quotidien
Magnesium fires cannot be extinguished with water because magnesium reacts with steam, producing hydrogen gas that adds fuel to the fire.
Importance industrielle
This reaction is a safety concern in magnesium processing plants and during fires involving magnesium components. Special dry chemical or sand extinguishers are required.
