Prerequisite, MATH 110. Chemistry 101 is the first half of a yearlong overview of the exciting field of chemistry, the study of the properties and changes of matter and energy. Students will be exposed to many new concepts, techniques and phenomena including atomic and molecular structure, stoichiometry, conservation of mass and energy and thermochemical changes. Chemistry 101 is a pre-requisite for Chemistry 102, and together, Chemistry 101 and 102 are the gateway to all courses in chemistry.
