Thermochemistry

Spend some time in a chemistry lab and you'll soon learn that some reactions are more exciting to watch than others: some reactions give off vast quantities of energy, others less so, and some even //absorb// energy from their surroundings. While studying this unit on thermochemistry, you will learn how to define and quantify //heat// and, much as you used stoichiometry to determine the changes in masses during a reaction, you will learn to determine the changes in heat and temperature during a reaction.
