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.

Mg + O2 --> MgO(s)
In water it reacts when boiling to form magnesium hydroxide and hydrogen:
Mg + H2O --> Mg(OH)2(s) + H2(g)

What happens to the mass of magnesium when heated?
it will decrease
What happens to the MASS when MAGNESIUM is burnt inside a CONTAINER?
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.
What is the atomic mass of magnesium?
The Atomic Mass of Magnesium is 24, the RAM (relative atomic mass) is 24.305.
What is the approximate atomic mass of magnesium Mg?
Magnesium is a meta element. Atomic mass of it is 24.
HOW TO GET percent of magnesium by mass?
You take the mass and divide it by the total mass of the element. Magnesium by itself is 100%.
What happens to the mass when magnesium is heated in air?
When magnesium is heated in air, it forms magnesium oxide and so the total mass increases.
What happens to the mass of magnesium when heated?
it will decrease
What happens when you magnesium is heated in air?
Magnesium's mass increases as it becomes magnesium oxide.
What happens to the temperature when the mass is increased in a chemical reaction involving magnesium and hydrochloric acid?
The temperature will increase the higher the mass of magnesium you add. It will increase the rate of the reaction.
What is the ratio of magnesium oxide mass to the magnesium mass?
.659
What happens when magnesium ribbon is burnt in air?
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.

HOW TO GET percent of magnesium by mass?
You take the mass and divide it by the total mass of the element. Magnesium by itself is 100%.
If the surface of the Mg ribbon you used were covered with thin oxide coating prior to the reaction would your mass percent calculation of magnesium be too high or too low explain?
higher..
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.
