That's because you are separating out both the Oxygen and the Hydrogen. Burntrubber is correct. If you took that "flammable Hydrogen" and heated it in the presence of the Oxygen you also got out it would burn (combine) and become water again. ETA: Also water is flammable in the presence of elemental fluorine which would just pull the hydrogen off the oxygen and create oxygen gas. |

Because you would have to add energy to break the bonds that were made when hydrogen was burned in the presence of oxygen in the first place. Since there is not enough energy to break down water into hydrogen to burn and free oxygen to consume as part of the burning process you basically get a wet match. Its the same reason carbon monoxide or dioxide is used as an extinguisher: the oxygen isn't free to bond with other elements during the burning process like atmospheric oxygen because there isn't enough energy to break the bonds.

It'll burn if you get it hot enough to rip the molecules apart. Try throwing water on a full-on thermite fire and see what happens
 I suggest not being close.

"Burning" means something combines with oxygen and gets into a lower energy state, while giving off heat.
If water burned it might become hydrogen peroxide H2O2 (among other things). But hydrogen peroxide has higher energy than water does, it decomposes into water while giving off heat. Extracting flammable H2 from water takes more energy than burning the H2 gives off (due to the inevitable inefficiencies). I don't think the water is burning when put on a thermite fire, I think it's helping the thermite burn by acting as an oxidizer. |

Just seems from the componets it would be highly flammable ( but we all know it's not) So in theory, water could be seperated and burnt over and over again ? |

Sounds like someone needs to tag along with him. Water WILL "burn," after a fashion. Combustion is a rapid oxidation reaction, generally accompanied by a release of energy in the form of heat and light. As water is already a stable molecule containing oxygen, it cannot combine with more oxygen to facilitate combustion. However, in the presence of other materials, particularly alkali metals, the oxygen in the water will have a greater affinity for these ions than for the hydrogen it is already bonded to. The oxygen will leave the hydrogen in order to oxidize the alkali metal, freeing the hydrogen in the form of binary gas. This oxidation reaction produces heat and light, though it is technically the metal which is "burning." Under proper conditions, the heat generated by the oxidation of the alkali metal will initiate the combustion of the liberated hydrogen gas using any surrounding air as an oxygen source. This would create water again and, again under ideal circumstances, the cycle can continue until either the alkali metal or the air source is depleted. The water is not technically burning, but it might look like it is. So the answer is that, if you're loose enough with your deffinition of "burn" then yes, water can be burned. |

It takes energy to separate H&O, when it combines it releases energy. That's like saying why can't I make my spring air pellet gun full auto? And just because elements behave one way in their atomic states doesn't mean it will behave the same way when it's combined with other elements (or itself) to make molecules. Otherwise salt would blow up in water and bleach our clothes at the same time. |

Quoted: creating water releases energy (exothermic) producing h2 and o2 from water requires energy (endothermic) asking why water doesn't burn is like asking why rocks can't roll uphill? Another excellent analogy. ENERGY. Hydrogen has a but load of potential energy, like a rock on the top of a hill. When it combines with oxygen, the energy is released to heat and a bit of light, this is like the rock in motion going down the hill, kinetic energy. Now react the water with sodium, aluminum, calcium or many other metals/metal oxides and the water reacts, releasing a hydrogen to become the metal hydroxide, also releasing a lot of heat. But that energy came from the metal, not the water. This potential energy was enough to kick off the hydrogen. |
