Why is burning of magnesium both a combination reaction and an oxidation reaction?

Answer and explanation

Correct answer: Two substances combine and oxygen adds to magnesium

When magnesium burns, it reacts with oxygen according to 2Mg + O₂ → 2MgO. Two reactants combine to form one principal product, magnesium oxide, so the reaction is a combination reaction. At the same time, oxygen is added to magnesium, which satisfies the school-level definition of oxidation. It is not a double displacement, decomposition or dissolution process. Therefore option A is correct.
