The "standard" answer is that if you burn magnesium in air, it will oxidize. The combustion product is magnesium oxide (MgO). But we're not done. It will also combine with nitrogen (air is about 79% nitrogen) to form magnesium nitride (Mg3N2), though it prefers to form the oxide. And yes, magnesium will burn in pure nitrogen. It will also burn in carbon dioxide (CO2) releasing carbon and forming the aforementioned magnesium oxide. Magnesium finds a lot of applications. Only steel and aluminum are more common. For instance, some automotive specialty wheels are fabricated of magnesium alloys (the "mag wheels" of the 60's). Magnesium is difficult to ignite when in the form of, say, a vehicle wheel. But the shavings or the powder can be lit more easily. When they burn, they do so with a brilliant white light. And burning magnesium is difficult to extinguish. Put water on it and it can explode, and it will burn more fiercely in any case. Dry powder or sand should be used to extinguish a magnesium fire. Use the link to one of many YouTube video shorts of a magnesium fire. This one features a firefighter applying water to a burning vehicle without knowing of a certainty what is actually involved. Surprise! Another link is provided to the Wikipedia article on magnesium. Be smart here. Don't be a jackass when conducting any investigations. Think them through and do your homework. The number of "experimenters" who end up in emergency rooms throughout the year is staggering. And some don't get there in one piece. Word to the wise.
hydrogen, when magnesium is being burnt it gives off the gas hydrogen and by the way i am in yr 8 and i gave u an key stage 3 question answer
(This is wrong)
Only light and heat come off burning magnesium, no hydrogen, I'm in yr8 too! Check your answers!!
Air is about 20% oxygen and 80% nitrogen. When magnesium burns, it reacts mainly with the oxygen, but also reacts with the nitrogen to a lesser extent. The two equations are:
2Mg + O2 --> 2MgO
Magnesium (metal) + Oxygen (gas) --> Magnesium Oxide
3Mg + N2 --> Mg3N2
Magnesium (metal) + nitrogen (gas) --> Magnesium Nitride
Magnesium oxide.
ash
the combustion of magnesium oxide is carbon+sulfur_carbonate sulfur
Combustion
magnesium nitride, Mg3N2 Please see the link.
Magnesium carbonate
Magnesium Carbonate
The product of the magnesium burning is magnesium oxide (MgO).
The product of combustion of metals are metal oxides. The final product of combustion of most organic materials, such as wood, also consists largely of metal oxides, such as potassium-, sodium- and magnesium oxides.

i love u :)
When magnesium is burnt in the presence of oxygen, the magnesium and oxygen combine to form the compound magnesium oxide. Therefore, this would be a combination combustion.
the combustion of magnesium oxide is carbon+sulfur_carbonate sulfur
Magnesium is extremely flammable. It will react even with water!!!!!!
Yes, the combustion of magnesium, or anything else for that matter, represents a chemical change. For magnesium, the combustion reaction results in the loss of magnesium and the production of magnesium oxide. Clearly a chemical change.
Water can be a product of combustion.
Oxidation-reduction, as magnesium is oxidized in this reaction
Combustion reactions
the product of any combustion rxn is CO2 (Carbon Dioxide) and H20 (water).
