The name of the new substance formed when magnesium is burnt in the air is magnesium oxide, when carbon dioxide is present in the atmosphere. However, when there is a presence of nitrogen in the air, the substance formed in magnesium nitride. Magnesium burns with a bright white, notably hot flame.
Magnesium oxide: 2Mg + O2 → 2MgO
Magnesium nitride: 3Mg + N2 → Mg3N2
