It increases because the mass of the magnesium adds to the mass of the oxygen. Also, the magnesium expands and magnesium oxide is formed.
The oxidation reaction is:
Mg + O2 = 2 MgO
Ithink it may be because it produces metal oxides when magnesium is burnt and this does not happen to woods
Because after oxidation new compounds appear: magnesium oxide (MgO) and copper oxides (Cu2O and CuO).
When magnesium is heated in air, it forms magnesium oxide and so the total mass increases.
Yes, magnesium burn in air.
I don't know how you know afterwards but when you burn magnesium in air it burns this really bright white light.
Magnesium's mass increases as it becomes magnesium oxide.
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.
When magnesium is heated in air, it forms magnesium oxide and so the total mass increases.
Yes, magnesium burn in air.
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.
According to the Law of Conservation of Mass, matter can neither be created nor destroyed, only change forms. Therefore, if you burn magnesium inside of a closed container, the mass will remain the same. ---- However you will get heavier ash than you had magnesium as the Oxygen in the air in your container will be transfered. But Total Mass is conserved.
I don't know how you know afterwards but when you burn magnesium in air it burns this really bright white light.
When magnesium is heated it reacts with oxygen in the air to for Magnesium oxide (MgO) 2Mg + O2 = 2MgO Magnesium oxide is white, so when it is heated, it produces a bright white light.
Magnesium's mass increases as it becomes magnesium oxide.
When a magnesium strip is heated strongly in air, it undergoes a chemical reaction called oxidation. Magnesium reacts with oxygen in the air to form magnesium oxide. The mass of the strip increases because magnesium combines with oxygen atoms from the air to form a heavier compound (magnesium oxide).
magnisium sulphate
Magnesuium burn in air at room temperature.
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.
Magnesium react with water and burn easily in air.
