Chemical of water is h2o.H(hydrogen can be burnt easily).O(oxygen are needed for burning).Why these two chemical which can burnt easily when they mixed up, they can't burnt?

Water is burnt hydrogen. You can't burn something twice.

basically because water is already burnt. it is a byproduct of fire. a lot of what you see in smoke is actually water vapor.
Burning is also called oxidation, or attaching oxygen to. Water already has oxygen so you can't attach more oxygen to it. when you take a fuel, say methane, which is carbon and hydrogen. you burn it, you are attaching free oxygen from the air to the carbon and hydrogen and you get carbon dioxide and H2O

The gas Hydrogen [H] will burn.
The gas Oxygen [O] will burn.
The liquid Water [H2O] will not burn, due to 2 hydrogen and 1 oxygen molecules combining, forming bonds and becoming H2O [a different chemical substance from it's parts when combined].

So, water does not burn, though when heated it evaporates as a gas into the atmosphere, becoming hydrogen and oxygen again as the bonds of the combination are broken.

Simply because it is a liquid. Yes, Hydrogen and oxygen can experience burning individually, but when their combined to form the liquid, it isn't possible. When combined, they form a separate "property".

When you burn hydrogen, you get water (H20). Oxidizing something is the same as burning it. You can't burn something that is already spent.

eg. Iron + oxygen = rust. It cannot rust again.

There is more to it if chemical formulas are used.

your english is awful. i will give you a very simplified answer. hydrogen and oxygen each has its own chemical properties. when they chemically combine, they get H20, a new compound that has different properties from Hydrogen and Oxygen.

Its because hydrogen and oxygen when they r separate they in a gaseous form and they have the otter orbital is not full and thy r reactive and help in combustion so that they can loose the xtra electrons so they catch fire and when they combine they are stable so don't under go reaction(s) so they don't catch fire.

Water is the most flexible product on the earth. From the frozen state to a liquid state to a boiling state to steam which is water vapor which evaporates quickly.

Hello,Water is highly Inflammable.But due to it bonding of electron of two different Atoms this activity is nearly finished.Dear it is Chemistry.
