General Chemistry (Chem 140)

COURSE DESCRIPTION: This chemistry course will begin your college-level investigation into the chemical sciences. We will cover topics, such as atomic theory, nomenclature (chemical naming), solutions, chemical reactions, stoichiometry (keeping track of elements during a chemical reaction), thermochemistry (heat generating reactions), chemical bonding, gas behavior, and molecular structure. The lecture portion of the course will follow the textbook subjects and uses practical applications and examples to illustrate these chemical principles. In the lab portion of the course you will have a hands-on experience applying the chemical principles to a real chemical problem. Chemistry is an exciting field with many job opportunities. It is our hope that you will enjoy the subject matter, see the relationship between chemistry to all aspects of our lives, and gain an appreciation for the interdisciplinary nature and relevance of chemistry.
