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
