When magnesium burns in oxygen to form magnesium oxide, what type of reaction is it?
Answer and explanation
Correct answer: Combination reaction
The reaction is \(2\mathrm{Mg} + \mathrm{O}_2 \rightarrow 2\mathrm{MgO}\). Here, two reactants, magnesium and oxygen, combine to form a single product, magnesium oxide. Therefore, it is a combination reaction. In a displacement reaction, one element replaces another element from its compound, which does not occur here.
