when we combine two or more elements to form a compound the elements do not retain their original property. that is the reason why water is different from hydrogen and oxygen.

A tiny misconception here, I think : Oxygen is not combustible. It is however an integral part of combustion. Combustion is merely a reaction in which oxygen combines with something else and energy is usually also produced in the process.
Hydrogen is combustible. The result, in fact, is water : 2 x H2 + O2 = 2 x H2O
Thus water is just combusted, or oxidised, hydrogen.
Water cannot be combined with oxygen to form another compound and release energy, and hence water is not combustible. If it was, water would not be the end product of hydrogen combustion.
And by the way, looking at some of the answers, I believe being a liquid does not affect combustion; I think there are liquids that can combust, though none comes to mind offhand. I might be inaccurate on this though.

Normally the hydrogen and oxygen combines only give the water U R mistake is H2+O its not H2+O2
The combustion will take place only when there was a meeting between a 2 molecules of the +ve and-ve things its not the same in the case of the water.

Lol.
combustion is an oxydation reaction.i.e materials combine with oxygen in a chemical reaction accompanied by the release of energy in the form of heat n light.
the energy released as a product of the reaction helps sustain the reaction.
Hydrogen is combustible. Oxygen is not combustible..its just required for combustion.
In H2O is a compound of hydrogen n water..it has different chemical properties.... it does not combine with oxygen to form any compound.. so there cant be any combustion.
But if u separate Hydrogen n oxygen through electrolysis.. then the hydrogen part can be used for combustion.

First of all, oxygen is not combustible, it only helps in combustion. Water is not combustible, because its chemical properties are different from those of hydrogen. Water is formed when hydrogen burns in oxygen. So water in itself is a product of combustion.

these two elements are gas combustible yielding a new substance called water, completely liquid , universal solvent and a completely different from the original combustible state, thats why when it boils through evaporation it produces the elements unstable and very gaseous again.

because after the combination of the two non metals i.e. H20 which forms a liquid which is non combustible.

u cant argue like this.coz h2 n o2 r elements n combine to form a compound. and a compounds properties r totally different frm the combining elements.

"Anything will burn given enough heat".
This is true for for anything that has not been oxidized as the burning process is oxidation-the bonding of oxygen. When hydrogen is "burned", or oxidized, one of the byproducts is H2O--water. So water is fully oxidized hydrogen. Thus water cannot burn because the hydrogen in it has already been "burned".

cose of d fact tht when u mix both off d two gases in equal parts such that hydrogen is added in 2 parts and water in one part then it starts mixin and at all temoeratures it sterts to become combustible and i dont know ha ha
