How is burning of magnesium both combination and oxidation at the same time?

Answer and explanation

Correct answer: Magnesium combines with oxygen to form magnesium oxide

The reaction is represented as 2Mg + O₂ → 2MgO. It is a combination reaction because two reactants, magnesium and oxygen, form a single product, magnesium oxide. It is also oxidation because oxygen is added to magnesium during the reaction. The reaction is not dissolution, decomposition, or precipitation, so the alternatives do not describe the observed chemical change.
