Answer 2

@mathmate So then, the burning splint would be for the CO2; glowing splint, oxygen; and pop test, hydrogen?

Answer 3

Yes, , but can you explain why?

Answer 4

CO2 because usually when the flaming splint is put in the gas, the gas will put out the flame. The glowing splint with oxygen because since oxygen is flammable, it com-busts (hence the spontaneous combustion theory; that people com-bust with the help of having too much oxygen in their blood)(showing a flash when the glowing splint is put in the oxygen). And finally hydrogen: since hydrogen is incredibly flammable, when the flaming splint is emerged in the hydrogen, it will make a pop! noise indicating the small explosion (an example of this is the Hindenburg Disaster). Yes?

Answer 5

Yes, your explanations are correct.

Note ALL the tests are not conclusive for the mentioned gases. They are tests to distinguish between the three gases, given that the unknown gas is one of the three.

For example, nitrous oxide (N20) will re-ignite a glowing splint. Nitrogen (N2) will put out a burning splint, and the "pop test" will test positive on any explosive gas.
