Answer:
If a flaming wooden splint or piece of paper is inserted into a tube of gas and the flame immediately goes out, then the gas is nitrogen versus oxygen (oxygen would feed the flame). If a wet piece of pH paper is inserted into a tube of gas and shows no change, then the gas is nitrogen versus carbon dioxide.
