Lots of ways. Density and spectroscopy come to mind, but if you're just looking for a quick test of a small quantity and you don't mind using it up in the process: A smoldering (not flaming) wooden splint inserted in a test tube of oxygen will flare into life. A flaming splint inserted in a test tube of hydrogen will cause a small "pop" (and probably blow the splint out) as the hydrogen combusts.

What is a greenhouse gas containing only hydrogen and oxygen?
Water vapor is a greenhouse gas that contains only hydrogen and oxygen.
Is hydrogen gas just hydrogen combined with oxygen?
No, Hydrogen gas is the diatomic element H, so it appears in nature as H2. The most common form of Hydrogen combined with Oxygen is H2O, or water.
Hydrogen peroxide decomposes to hydrogen and oxygen in what states of matter?
liquid or gas
What is water when it is broken into hydrogen and oxygen?
When separated into its component parts, hydrogen and oxygen, the original water no longer exists.
How many atoms of hydrogen does oxygen have?

What do you get when you electrolyse water?
Hydrogen and oxygen are the products of electroysis of water .
What gas is heavier hydrogen or oxygen?
oxygen gas is heavier than hydrogen gas
How do you write the formulae for hydrogen gas oxygen gas?
Hydrogen gas is H2. Oxygen gas is O2.
Is a gas given of when water splits into hydrogen and oxygen?
When water splits, hydrogen gas and oxygen gas are formed.
What is oxygen gas and hydrogen gas?
They are both diatomic gases. Hydrogen will explode in oxygen to produce water.
Which is more heavier - hydrogen gas or oxygen gas?
Mass of Hydrogen gas:- 2g/mol Mass of Oxygen gas :- 32g/mol Therefore, Oxygen gas is more heavier
What is heavier Hydrogen gas or oxygen gas How do you know?
Oxygen is heavier as it has a mass number of 16 whereas hydrogen has a mass number of 1. Both form diatomic molecules (molecules of two atoms) making the formula masses 32 for oxygen and 2 for hydrogen.
What is a greenhouse gas containing only hydrogen and oxygen?
Water vapor is a greenhouse gas that contains only hydrogen and oxygen.
What state of matter is oxygen and hydrogen?
oxygen and hydrogen are a type of matter called gas
What is a colourless tasteless odourless gas?
Cheese right someone put cheese how is that a colourless gas i will never know but i think the answer is gas
If you chemically mix Oxygen gas with Hydrogen gas then which liquid is produced?
If one chemically reacts oxygen gas and hydrogen gas, any liquid produced is water.
Oxygen and hydrogen are in what state?
Gas
