When two oxygen and one hydrogen is mixed together, it forms water, or H2O.

NASA uses a combination of hydrogen and oxygen in their fuel tanks to ensure lift-off so it produces a large amount of energy in the right proportions as the reaction is very exothermic.

If you mix hydrogen gas and oxygen gas they don't react at all unless you heat them.
