Out of curiosity, I know oxygen is flammable, and that hygrogen is flammable. Yet, water is H2O. (2 hygrogen & 1 oxygen molecule) And we all know that water is not flammable... do they cancel each other out or something?

Because it is already burnt. It is the product of a combustion. e.g. a hydrocarbon

O2 is not flammable, it's an oxydizer, it makes fire hotter and bigger, and burn faster, H2 is flammable, Water is H2O, a molecule with both, I guess that it needs the components seperatly for the reaction to occur. I would also say it have something to do with the electrons or something like that, but I didn't read much in that details.

EDIT: Yea, the oxidizing agent gets electrons, the other component gives electrons, so I guess them beeing in the same molecule cancels the effect

Do the electrolysis of water and you got H2 and O2, or like I like to call it, HHO, explosive mix of O2 and H2 :D

The molecule is also polarized with a slightly positive charge on the side with the Hs and a slight negative charge on the O side

I got put into dual award because I accidently messed up my Year 9 end of year exam. It is still in the textbook though.

Yeah, it's in my OCR chemistry revision guide. I'm revising it now. JOYYYYYY.

21st Century Science? Apparently it's the most messed up of all the courses.

That's what my dad said, he teaches chem. It's a tick-box exam paper, so I have it easy I suppose :P

I have to do it too. I got 92% and 96% on my biology end of unit papers. Shame I failed the coursework D:

Can someone explain...
