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 else can I help you with?
Hydrogen peroxide decomposes to hydrogen and oxygen in what states of matter?
Hydrogen peroxide decomposes to hydrogen and oxygen in the gas phase.
What state will the elements chlorine helium hydrogen and oxygen be at room temperature?
At room temperature: Chlorine: gas Helium: gas Hydrogen: gas Oxygen: gas
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.
Word equation for hydrogen and oxygen?
Hydrogen + Oxygen = Hydrogen Oxide
Why are bubbles produced when hydrogen peroxide reacts with catalase?
When hydrogen peroxide reacts with catalase, an enzyme found in cells, it breaks down the hydrogen peroxide into water and oxygen gas. The oxygen gas is produced in the form of bubbles due to the rapid release of oxygen gas during the decomposition reaction. This reaction is catalyzed by catalase, which helps speed up the decomposition of hydrogen peroxide into water and oxygen.
What gas is heavier hydrogen or oxygen?
oxygen gas is heavier than hydrogen gas
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.
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.
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
Hydrogen peroxide decomposes to hydrogen and oxygen in what states of matter?
Hydrogen peroxide decomposes to hydrogen and oxygen in the gas phase.
When hydrogen gas and oxygen gas react as much oxygen gas than hydrogen gas is required?
The reaction between hydrogen gas and oxygen gas forms water, with 2 moles of hydrogen gas reacting with 1 mole of oxygen gas. This means that twice as much hydrogen gas is required compared to oxygen gas for the reaction to occur completely.
What do you get when you electrolyse water?
When you electrolyze water, it separates into its constituent elements: hydrogen and oxygen gases. This process involves passing an electric current through water, causing the water molecules to break down into hydrogen gas at the cathode and oxygen gas at the anode.
Which word equation shows hydrogen reacting with oxygen to form water?
Hydrogen gas + Oxygen gas -> Water.
What state will the elements chlorine helium hydrogen and oxygen be at room temperature?
At room temperature: Chlorine: gas Helium: gas Hydrogen: gas Oxygen: 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.
