Wikipedia is a great place to start: www.wikipedia.org.
But actually I would start with your chemistry book and the names
Dalton and Lavoisiere, expecially for conservation of mass, and the
name Joule for conservation of energy. It will be really important for
you to understand the problem they were trying to figure out. Folks
were well aware that you could combine two substances, but no one knew
there was any *quantitative* rules surrounding it. They knew, for
example, that combining hydrogen with oxygen produced water, but they
had no idea how much of the former produced how much of the latter.
Lavoisiere was the first to be careful enough to show that not a
fraction of an ounce of matter was lost or gained in that reaction.
Lavoisiere was a neat-freak and compulsively detail-minded. You could
spend a whole essay on how much money he spent on equipment and how
delicately he fine-tuned his measurements and how carefully he captured
all of the material in the reaction to show what he showed.
