Formation of Magnesium Oxide
2Mg + O2 → 2MgO
Overview
Magnesium burns brilliantly in oxygen with an intense white flame to produce magnesium oxide. This reaction is so exothermic that it produces temperatures exceeding 2500 C. The bright light emitted was historically used in photography flash powder.

Everyday Example
Sparklers and fireworks use magnesium to produce their characteristic bright white sparks and flashes.
Industrial Importance
Magnesium oxide is used as a refractory material in furnace linings, as an antacid in medicine (milk of magnesia), and as a component of animal feed supplements.
