Light a splint on fire, and then blow the flame out. You want your splint to be glowing red. Then, simply put the splint into the mouth of the the test tube, and if your splint re-lights up into a flame, you'll know it's oxygen gas.
if you want to test if their is oxygen in a test tube than put an empty test tube on the stove and then if their is fog around the sides than yes if there is no fog then no
The test for oxygen is to insert a glowing splint into a test tube and see if it glows brighter or re-ignites.
Place a glowing splint into the test tube. If the glowing splint relights, then oxygen is present, otherwise oxygen is not present.
The glowing splint will relight if you place it in a flask with oxygen. Scientists do this as a test for oxygen so if it relights, then that means the flask contains oxygen.
Oxygen
If only oxygen is in the test tube, it may burst into flame.
There are a few ways you can remove the oxygen from a test tube. You can flick the side of it until the bubble surface for example.

If a test tube is filled with oxygen when you put a glowing splint into it, the splint will relight. (To make the splint glow you have to light it then blow it out and put it into the test tube immediately.) Hope this helps. XD XD
is carbon dioxide and or hydrogen in a clean empty test tube
Ya... In a test tube add some aluminum foils and some amount of NaOH... Introduce the flame near mouth of the test tube... Then see the magic...

If you put a lit match in a test tube of oxygen it will burn with more energy.

A glowing splint will burst into flame/smoke in pure oxygen (using a test tube).
put oxygen in a test tube put a glowing splint inside and it will have a squeaky pop sound
