At room temperature, a sample of pure magnesium metal combines with oxygen to form a thin skin of magnesium oxide. At higher temperatures, it burns with a blinding white light, and because of this property it's used in fireworks.  Read more at the link:

It Produces brilliant white light.Magnesium Oxide and Carbon are formed. Mg + O2 gives MgO and C

2Mg + O2 -> 2MgO (Magnesium Oxide)

But we all know that air is made not only of O2, but N2 too. The O2 is responsible for combustion; the N2, however, is unreactive at normal temperatures.

When we burn Mg in the air, the result will be 2 products: magnesium oxide (MgO) and magnesium nitride (Mg3N2).

The equation of a reaction of oxygen and magnesium to form magnesium is as follows:

2Mg (aq)+O2 (aq)-->2 MgO (s)

When it burns in oxygen, it would produce a strong white flame and its intensity may cause your eyes to go blind if you stare too close at it. It would react to form a compound called magnesium oxide which has a wood-ash appearance.

When you burn Magnesium in air, it react with oxygen. Producing Magnesium Oxide.

Magnesium + Oxygen ---> Magnesium Oxide

(2) Mg + O2 ----> (2) MgO

It produces a white flame and the end result is production of magnesium oxide.

Chemically, when magnesium reacts with oxygen it forms magnesium oxide. It produces a white flame during the chemical reaction
