OXYGEN RELIGHTS A GLOWING SPLINT Oxygen.
In a positive test for oxygen gas, a glowing splint inserted into a test tube of the gas will reignite, indicating the presence of oxygen. This is a characteristic test for the presence of oxygen, as the gas supports combustion.
Helium is a group 8 element, and therefore a noble gas. It has no free electrons to bond to oxygen, therefore it won't oxidise or combust. So no, it won't. As a side note, you may hear of stars "burning" helium, but this Ian burning, its nuclear fission :)
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 :)
One way to confirm that the gas liberated is oxygen is by performing the gas test. Place a glowing splint into the gas sample - if the splint re-ignites, it indicates the presence of oxygen due to its ability to support combustion. Additionally, oxygen can also be identified by its colorless and odorless characteristics.
What do you mean? To test for oxygen being produced, light a splint, blow it out then put it over the object you beleve is producing oxygen and if the splint re-lights oxygen is being produced.
Oxygen will rekindle or relight a glowing splint.
It rekindles (flames up) the glowing splint..
More or less pure oxygen relights a glowing splint, while air oxygen (20%) will not do so.
The test for oxygen is to insert a glowing splint into a test tube and see if it glows brighter or re-ignites.
In a positive test for oxygen gas, a glowing splint inserted into a test tube of the gas will reignite, indicating the presence of oxygen. This is a characteristic test for the presence of oxygen, as the gas supports combustion.
A glowing splint will reignite in the presence of oxygen due to the process of combustion. Oxygen feeds the combustion reaction, allowing the splint to continue burning.
Oxygen would re-light a glowing splint

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.
