# Identify from the reaction the reactants that undergo oxidation and reduction. 2Mg + O2 → 2MgO - Science and Technology 1

Short Note

Identify from the reaction the reactants that undergo oxidation and reduction.

2Mg + O2 → 2MgO

$\ce{2Mg + O2 ->[\Delta] 2MgO}$

#### Solution 1

In a reaction, magnesium is changing to magnesium oxide. That means, oxygen is being added to magnesium. Addition of oxygen to a substance is called oxidation, so magnesium undergoes oxidation.

#### Solution 2

Mg undergoes oxidation and O2 undergoes reduction.
