ah yes, the classic which gas is in which test tube experiment...
Oxygen accelerates the combustion of organic material. The wood splint will burn more brightly and quickly if placed in oxygen. If the splint is 'blown out' leaving only a glowing tip it will reignite when placed in oxygen.
the lighted splint would stop burning as Helium does not burn.
When a lighted splint is put into a glass jar of helium, the splint will immediately extinguish because helium is an inert gas that does not support combustion. The lack of oxygen in the helium prevents the splint from continuing to burn.
You can't express that reaction because there isn't one: as CO2 is a well-known fire extinguishing agent, if you put a burning splint in CO2 the splint will go out. And the reason it will go out is CO2 displaces oxygen, which splints need to burn.
Insert a lighted splint into the reaction test tube. If it extinguishes with a "pop" sound, Hydrogen is present. The duller the pop the purer the hydrogen is.---------------------------------------------------------------------------------------------P.S. that's a burning splint.
Nothing, helium is inert.
When you put a lighted splint in nitrogen, it will continue to burn but more slowly than in oxygen due to the lack of oxygen in nitrogen. Nitrogen is an inert gas that does not support combustion, so the splint will eventually go out.
The glowing splint would extinguish in nitrogen. Nitrogen gas is inert and does not support combustion.
The burning splint is extinguished by the carbon dioxide given off from the calcium carbonate. CaCO3 --heat--> CaO + CO2 ==================================================

a glowing splint in hydrogen gas will make a popping sound. this is because hydrogen is very reactive and when it comes into contact with the oxygen in the air it reacts with it and that is what you hear in the popping sound.
it goes out A glowing splint needs oxygen to basically keep glowing. It is a small fire in a way. When the glowing splint is added into an environment full of carbon dioxide, the splint goes out. Carbon dioxide in this case smothers the flame restricting the use of oxygen in combustion thus putting the flame out.
Cloudy white gas is all too vague. Say if it is CO2, the splint will quench itself as the 3 ingredients for fire are fuel (splint) ignition, and O2. If you get rid of O2, you lose ability to sustain a flame. If it is hydrogen gas for example, you will hear a pop, if the H2 is in low quantity.

1) Put a burning splint near the mouth of a test tube which you think contains hydrogen. If you hear a pop when you touch it with the splint then there is hydrogen.
