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.
It will burn with oxygen from air.
Mg + O2 --> MgO(s)
In water it reacts when boiling to form magnesium hydroxide and hydrogen:
Mg + H2O --> Mg(OH)2(s) + H2(g)
magnesium burns readily in air with a brilliant white flame. it burns even brighter in pure oxygen, producing a white ash, magnesium oxide
It is an oxydation:
2Mg + O2 = 2MgO
The mass increase because the magnesium oxide is formed.
The magnesium catches fire when it is heated. This is a reaction with oxygen so magnesium oxide is formed, which is heavier than the magnesium at the start.

it will decrease
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.
The Atomic Mass of Magnesium is 24, the RAM (relative atomic mass) is 24.305.
Magnesium is a meta element. Atomic mass of it is 24.
You take the mass and divide it by the total mass of the element. Magnesium by itself is 100%.
When magnesium is heated in air, it forms magnesium oxide and so the total mass increases.
it will decrease
Magnesium's mass increases as it becomes magnesium oxide.
The temperature will increase the higher the mass of magnesium you add. It will increase the rate of the reaction.

Magnesium is an extremely reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper for removing this layer so that the underlying metal can be exposed to air.

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.
