Hydrogen is separated from water via electrolysis, which requires more energy than you'll ever get from burning the hydrogen. There's only one good reason to recover hydrogen via electrolysis, and that's if you're a jeweler. Jewelers' torches all burn hydrogen and oxygen which they get through electrolysis of water, because it saves them from having to handle and store welding gases. With an electrolyzer, they can create their gases when they need them, and only as much as they need.

When hydrogen burns what gas is produced?
Water vapour.
Is hydrogen present in air?
Yes, but in very small amounts. It is present in water vapour.
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water cannot be separated into hydrogen and oxygen by boiling. Boiling is a physical change which means the molecule doesn't change at all--liquid water and water vapor are both H2O. Water can be separated into hydrogen and oxygen using electricity, this would be a chemical change.
How hydrogen detected in the carbon and hydrogen test?
To test for hydrogen in the given substance, a dry sample is needed. Burn it in excess of oxygen. If the vapour turns white copper sulfate into blue colour, it indicates that there is water in present in the vapour. Hence, the organic compound contains hydrogen.
What happens to boiled water?
Hey there......... when water is heated the molecules of water i.e. Hydrogen and oxygen gets heated and get lite and forms vapour which is carried on by air
When hydrogen burns what gas is produced?
Water vapour.
What fuel can be separated from water molecules?
Hydrogen can be separated from water molecules :)
What is vapour?
a pure gas of oxygen and hydrogen The water cycle is driven by the Sun's energy. When water evaporates, it turns into the invisible gas called water vapour.
How is air and warter alike?
Both contain hydrogen and oxygen and there is water vapour in the air.
Fuel-cell cars use hydrogen gas and release what into the atmosphere.?
Water vapour.
Is hydrogen present in air?
Yes, but in very small amounts. It is present in water vapour.
What is air in a gas?
Water Vapour because it is made up of the Hydrogen and Oxygen atoms.

Water Vapour because it is made up of the Hydrogen and Oxygen atoms.
What is a by-product of burning hydrogen gas?
There is only one product - water. Hydrogen burns in the oxygen in air to form hydrogen oxide or water vapour. 2H2 (g) + O2 (g) = 2H20 (g)
What is produced directly from the splitting of water?
Splitting water results in oxygen and hydrogen. The water element is separated into two hydrogen atoms and one oxygen atom.
