Water

We know that H_20 is water. So thus, the chemistry equation for water is H_2 + O, right? If I am wrong, can anyone help me on this one a little bit?

Thanks,

J.

The correct equation would be this:

2H_2 + O_2 --> 2 H_2O

When in pure form, oxygen and hydrogen always exist in diatomic molecules.

i would just like to add that though the equation is pretty simple the reaction itself isnt....an extraordinary amount of energy is required to carry out the above equation...something that is substantiated by the fact that scientists have not suceeded in producing water as of yet..

Actually, all it takes is a match to make water, since hydrogen and oxygen explode when mixed in the presence of enough heat. The result is water.

A chemical equation is for a particular chemical reaction, not a particular compound. Water is produced in many different chemical reactions.

True, though Infinity's chemical equation is quite common. It explains, for example, why there is so much moisture coming out of cars' tailpipes.

The more difficult bit is extracting hydrogen and oxygen from water. Which can be done using electrolysis.

Dissolve a conductor into the water and zap with current. Good 6th grade science experiment.
