What happens when hydrogen is combined with oxygen?

Answer 1

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.

Answer 2

it makes water but hydrogen + oxygen might not combine property so it will be very hard to make water but with hydrogen it is very cold and that is why water is pretty cold and when the two gases are combined they will never disconnect from each other and that is why we got steam instead of more oxygen and hydrogen.

Answer 3

When hydrogen is combined with oxygen in the presence of a spark or flame, it undergoes a chemical reaction to form water. This reaction releases a large amount of energy in the form of heat and light, which is why hydrogen and oxygen are often used as rocket propellants.

Answer 4

Hydrogen and oxygen are both gases as room temperature. When combined they form one of two products - water or hydrogen peroxide.

Answer 5

Well... more than likely you will get water. like... H2O

Answer 6

YOU GET HEAT LIGHT AND WATER!!! WOOHOOO!!!!

If you combust/burn it.. that is....

Answer 7

You have a mixture of two elements. Were you going to add activation energy, to get them to form some water vapor?

Answer 8

Either water (H2O) or hydrogen peroxide (H2O2) are formed as a result of the chemical bonding, however hydrogen peroxide requires a more complex process to be created than water.

Answer 9

heat
