It is said that Hydrogen is highly flamable and oxygen assists the burning. WHY then the water isn't flamable?

Answer 1

The process of combustion, or burning, is simply combining something with oxygen very rapidly, in a reaction that releases heat. When hydrogen burns, the result is water, which is just fully oxidized hydrogen. In effect, water is the "ash" of burned hydrogen.

And like all other forms of ash, because water is already fully oxidized, it can no longer accept oxygen, and therefore cannot burn.

Answer 2

Often in chemistry by combining two very potent or dangerous chemicals we get a harmless and stable product. For instance, H and O mixed do give you water, but water is liquid, and the bonds which hold the two oxygen atoms to the hydrogen atoms are not easily seperated into their volitale gas forms.

Another example is Sodium and Chlorine. Apart these chemicals are deadly, and should be handled with care. Together they for NaCl... common table salt.

Answer 3

First learn how to write in english; then learn the wonders of chemistry.

Think about it. In H2O the Hydrogen and Oxygen are already combined - highly stable and not much of a reaction. But when hydrogen and oxygen combine to make H2O, alot of energy is released - i.e. an explosion.

Answer 4

Hydrogen and oxygen have bonds that are weak in nature, when hydrogen and oxygen are mixed together under a flame these bonds break easily and form more stronger stable H-O bonds.

H-O bonds on the other hand when they come into contract with fire will not break, and due to water blocking out the fire source from oxygen, the fire will die out.

Answer 5

Hydrogen is very unstable on its own due to its electron count. When Hydrogen and Oxygen are combined, they become very stable with a good amount of electrons in its orbitals which will not release as much energy

Answer 6

Think of water as 'already burned' hydrogen. Burning is oxidation, and that means oxygen added. So it is behaving perfectly normally as a consumed fuel.

Answer 7

Yes, hydrogen is flammable and oxygen assists burning. But combine them together and they form water. It is a more stable chemical, formed by combining hydrogen and oxygen.

Its like wood, after being burnt, forms ash - just because wood is flammable, doesn't mean ash is flammable.

Answer 8

its the individual elements that are flammable not the combined form. since the hydrogen and oxygen have already reacted they have reached the lowest energy possible there require massive amounts of energy to become reacted again.

Answer 9

Water posses very special qualities, but sorry its non flamable.

Answer 10

hydrogen and oxygen monotomic GASES are flammable. Just because water has hydrogen and oxygen atoms in its molecular structure doesn't mean it has the same physical properties. :)
