Energy Changes in Chemical Reactions
Thermochemistry is the branch of chemistry
concerned with the heat effects that
accompany chemical reactions.
Heat is the transfer of thermal energy between
two objects (a system and its sur

Early Chemical Discoveries
Law of Conservation of Mass (Antoine Lavoisier 1774):
Matter is neither created nor destroyed in a chemical reaction.
The atoms with which you start are the same as the ones with
which you end.

The typical chemical makeup of natural gas is a bond between Carbon and Hydrogen
atoms. The most common composition of natural gas is Methane, which has a chemical
formula of CH4. This is 70-90% of the makeup of natural gas according to
