Insert a glowing splint into a test tube of the gas.

What is the positive result of the test for oxygen gas?

The glowing splint relights.

True or false? Oxygen is flammable and burns with a pop in the splint test.

False. Oxygen does not burn; it supports combustion, so it relights a glowing splint.

An unknown gas relights a glowing splint. Which gas is it, and how do you know it is not hydrogen?

Oxygen. Hydrogen would burn with a squeaky pop with a burning splint, not relight a glowing splint.

True or false? The test for oxygen is that a burning splint relights.

False. Oxygen relights a glowing splint, not a burning one.
