If heated, magnesium oxide or MgO (a white powder) is formed.
I also want to know what is the compound which is formed when the magnesium ribbon is burnt in air
Magnesium is weighed and then heated in a crucible. It reacts with oxygen to produce the oxide. It can be shown that there has been an increase in mass.
the positive test for oxygen is very simple. all that needs to happen is a vile must be filled 1/4 with hydrogen peroxide and a glowing splint must be inserted in t the vile . the splint will reignite after it is inserted int the vile.
The magnesuim melts and the reaction of it is it produces a bright light ! then when it has cooled down the magnesuim turns into magnesuim oxide because the magnesuim and oxygen attach together because the particles mix together to make magesuim oxide! :)
Blood Test
you put the hydrochloric acid in a test tube then you put the magnesium metal in the test tube with the hydrochloric acid in it then you put a cork on the top ofthe test tube and watch it fizz.

A glowing splint will burst into flame/smoke in pure oxygen (using a test tube).

Lots of ways. Density and spectroscopy come to mind, but if you're just looking for a quick test of a small quantity and you don't mind using it up in the process: A smoldering (not flaming) wooden splint inserted in a test tube of oxygen will flare into life. A flaming splint inserted in a test tube of hydrogen will cause a small "pop" (and probably blow the splint out) as the hydrogen combusts.
If a doctor informs you that you need a magnesium test, you do not need to fast beforehand. A magnesium test will check for kidney problems, muscle problems, and if you are low on calcium.
If only oxygen is in the test tube, it may burst into flame.

SST
through the copper sulphate test, magnesium sulphate and calcium chloride test.
You need to try and relight a glowing splint. If it does relight, then there is oxygen gas.
