Awesome... I'm bookmarking it. Interestingly I've always been puzzled how there can be both H2O (water) and H2O2 (hydrogen peroxide) when the valences are different. I always thought they had to add up to zero. But apparently a -1 valence is legal but means the H2O2 is an acid. Cool.

Johnny was a chemist's son. Now Johnny is no more. What Johnny thought was H20, was H2S04.

Teacher: Johnny, what's H2SO4? Johnny: Er, hang on. I know this one. It's on the tip of my tongue... Teacher: Well spit it out quick, it's sulphuric acid!

Johnny loved his chemicals, But could not pronounce their names! He was OK with boron But not with dichlorodiphenyltrichloroethane.

That's really cool, thanks ! Note also: plenty of good stuff on the same site.
