What is the nature of the white powder formed when magnesium burns?

Answer and explanation

Correct answer: Basic oxide

Magnesium burns in oxygen to form white magnesium oxide: \(2Mg + O_2 \rightarrow 2MgO\)। MgO is a basic oxide and can react with water to form basic magnesium hydroxide: \(MgO + H_2O \rightarrow Mg(OH)_2\)। In contrast, an amphoteric oxide reacts with both acids and bases, whereas MgO is not generally classified as amphoteric.
