CHEM 113. Concepts of Chemistry A one-term chemistry course designed for non-science majors. In this course we examine what gives rise to three-dimensional shapes of molecules and we explore how the structure and composition of molecules gives rise to chemical reactivity. Our goal is to understand readily observable phenomena (e.g. removal of grease by soap, storage of toxins in fat tissues, cancer, viruses, etc). Topics include those of current global interest such as anthropogenic forces on the environment and energy producing technologies. The course includes one four-hour lab per week. 6 cr., MS; LS, QRE, Not offered in 2012-2013.

CHEM 122. An Introduction to Chemistry An introduction to the fundamentals of chemistry to prepare students to enter subsequent chemistry courses (Chemistry 123 or 128). Atoms and molecules, stoichiometry, and gases will be covered in the course. Although learning through discovery-based processes, small groups, and short laboratory experimentation will occur, this is not a lab course and doesn't fulfill the requirements for medical school. This course assumes competence with simple algebra, but no prior chemistry experience. Students with high school chemistry should probably take Chemistry 123 or 128. (Determined by the self-administered Chemistry Placement Evaluation, Chemistry Home Page). 6 cr., MS; NE, QRE, Winter—M. Whited

CHEM 123. Principles of Chemistry An introduction to chemistry for students who have taken high school chemistry or Chemistry 122. Topics include the electronic structure of atoms, periodicity, molecular geometry, thermodynamics, bonding, equilibrium, reaction kinetics, and acids and bases. Substantial independent project work is included in the lab. Each offering will also focus on a special topic(s) selected by the instructor. Students cannot receive credit for both Chemistry 123 and 128. Prerequisite: Adequate secondary school preparation as indicated by the self-administered Chemistry Placement Evaluation (Chemistry Home Page) or Chemistry 122. 6 cr., MS; LS, QRE, Fall,Winter,Spring—C. Calderone, D. Kohen, M. Whited

CHEM 128.

These topics and the chemical principles behind them are addressed through an emphasis on the earth's atmosphere. One four-hour laboratory per week. Because this course covers the major topics of Chemistry 123 (but with an environmental emphasis), students cannot receive credit for both Chemistry 123 and 128.
