Mikey Way (the bassist, for those who don't know) came up with the name. The name came from an Irvine Welsh novel Ecstasy: Three Tales of Chemical Romance. The band just changed it to My Chemical...
The chemical or chemicals formed in a chemical reaction are called the product of the chemical reaction.
Not as far as I know.I think it's still My Chemical Romance, they had no reason to change it.so, yeah... they better not have! ;)
