First off, it doesn't burn more, it burns quicker. This is because It's reacting with the oxygen, and in a 100% oxygen environment there's simply more oxygen to react with (the air is 21% oxygen).

Why do iron and magnisium burn more in oxygen than in air?
Iron and magnesium burn in air under the right circumstances becasue they combine rapidly with oxygen. (Fire is just the rapid combination of oxygen or another oxidizer, wiht a fuel.) Oxygen is only about 20% of air. If you provide pure, 100%, oxygen under the same circumstances, there is more oxygen to combine with the iron or magnesium, so they can burn faster.
Why does magnesium get heavier when its burned?
What happens when magnesium burns? What do you need for magnesium to burn? Will magnesium burn if you have it in a closed container? No. Why not? It needs air. Why does it need air? There is oxygen in the air. Magnesium needs oxygen to burn. So, when magnesium burns, you start with magnesium and end up with a compound that contains both magnesium and oxygen. Magnesium has an atomic weight of 24. Oxygen has an atomic weight of 16. So if you start out with 24 grams of Magnesium you should end up with 40 grams of Magnesium Oxide.
What temperature does oxygen react with magnesium?
Magnesuium burn in air at room temperature.
What happens during the reaction of magnesium burning in oxygen?
Magnesium oxide is formed. Though Magnesium will burn brighter in oxygen than in air, as the concentration / amount of O2 is more in pure oxygen than in air (which has about 20% O2).
Is burn magnesium a chemical change?
It's a chemical change. The magnesium reacts and combines with the oxygen in the air.
What is a scenario for increasing temperature influence a chemical change?
At room temperature, magnesium and oxygen react very slowly. However, when you burn the magnesium, it will rapidly combine with oxygen in the air to form magnesium oxide, MgO.
Why when magnesium ribbon is burnt the ash is heavier?
When Magnesium burns, it is actually combining with oxygen in the air to form a new compound, magnesium oxide. If we were to carefully weigh a piece of magnesium before and after burning it, you would see that its weight increased by about one third. For example, if you start with 100 grams of magnesium, after the burn you would end up with about 130 grams of magnesium oxide. The fact that the magnesium oxide you create by burning is powdery, means that it takes up more space (size or volume) than the solid magnesium did.
Does magnesium burn better in nitrogen or oxygen?
Magnesium burn in oxygen; burning is an oxidation reaction. Magnesium also reacts with nitrogen at high temperature to form Mg3N2 where the magnesium is oxidised, i.e. loses electrons. When magnesium is burnt in air some nitride is produced which hydrolyses to give a faint smell of ammonia. The enthalpy of formation (heat of reaction) is greater for MgO than for Mg3N2.
Does magnesium react with the gases in your atmosphere?
HI what a retard who would rite hi? lol Magnesium metal is burned in air forming magnesium oxide. This is an interesting oxidation/reduction reaction because it shows the burning of a metal, because the products of the reaction are visible after wards, and because it produces a lot of light.at
How could you prove that magnesium is a more reactive metal than zinc or iron?
Magnesium react with water and burn easily in air.
What is the word equation for burning magnesium in the air?
The word equation is magnesium + oxygen(air) = magnesium oxide. The Balanced chemical eq'n is 2Mg(s) + O2(g) = 2MgO(s)
Will magnesium burn with a brilliant white light if heated above 100 degrees?
Yes, magnesium burn in air.
