Well, I wonder if little shadowqueen is going to learn much about chemistry by surfing the entire internet hoping to find these 4 equations. Jup, that's what they teached me in my first 2 years of chemistry: "how to surf the internet and memorize trash". *sigh*

Try wikipedia shadowqueen. www.wikipedia.org all of this information will be available there.
