OXYGEN RELIGHTS A GLOWING SPLINT Oxygen.
By chemical analysis; also a candle burn in oxygen (or in a gas containing oxygen) but not in nitrogen, argon, carbon dioxide.
Oxygen can be used to relight a glowing splint, which is why if you blow on a fire, it temporarily increases in size.
Hydrogen test - commonly know as the pop test Basically you collect the gas in a test tube. Light a splint on fire and put it in the test tube with the gas, if you hear a "pop" sound and the splint goes out then the gas should be Hydrogen Oxygen test Collect the gas in a test tube, light a splint, but blow it out so that it is glowing. Then put it in the test tube with the gas, if the splint relights then the gas should be oxygen Hope that helps :)
If you leave it out, it just turns white instrad of the glowing color.
OXYGEN RELIGHTS A GLOWING SPLINT Oxygen.
More or less pure oxygen relights a glowing splint, while air oxygen (20%) will not do so.
By chemical analysis; also a candle burn in oxygen (or in a gas containing oxygen) but not in nitrogen, argon, carbon dioxide.
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 can be used to relight a glowing splint, which is why if you blow on a fire, it temporarily increases in size.
Place a glowing splint into the test tube. If the glowing splint relights, then oxygen is present, otherwise oxygen is not present.
Take a test tube and put inside it a glowing splint. If the splint relights, the oxygen is present. If not, there is no oxygen.
glowing splint ... if it relights then the chemical reaction produces oxygen.

It doesn't stop glowing
Yes, a star is a glowing sphere of hot gas.
