When magnesium burns, with which gas does it react to form magnesium oxide?

Answer and explanation

Correct answer: Oxygen

Magnesium burns with a bright white flame because it reacts with oxygen in the air. The balanced equation is 2Mg + O₂ → 2MgO, showing that oxygen combines with magnesium to form magnesium oxide. Nitrogen is abundant in air but is not the reacting gas in this standard combustion example. Chlorine and carbon dioxide are not the intended reactants. Therefore option B is correct.
