The Principles of General Chemistry sequence (Chem 105/106) is designed for students who have only one year of high-school chemistry or physics OR students who would benefit from a review of chemistry fundamentals.

This course traces the development of chemistry from early atomic theory to modern descriptions of structure, bonding, and intermolecular interactions. Over the course of the semester, the students learn how macroscopic observations of stoichiometry, chemical reactions, the properties of elements and compounds, and chemical periodicity developed into the microscopic understanding of molecular structure and bonding. The semester begins with fundamentals related to stoichiometry, chemical reactions, solution chemistry, and gas properties, with an emphasis on quantitative problem solving. The octet rule, Lewis structures, and valence-shell-electron-pair repulsion (VSEPR) theory are then introduced as early efforts to describe the stability and structures of molecules. The localized electron model (LEM) and molecular-orbital theory (MOT) are next described as modern descriptions of chemical bonding. The course concludes with intermolecular forces such as hydrogen bonding and van der Waals interactions.

This course covers chemical equilibrium, thermodynamics, and kinetics at a fundamental level, with an emphasis on in-class problem solving. Gas-phase reactions, heterogeneous (multi-phase) reactions, acid-base reactions, and solubility equilibria are introduced first. Chemical thermodynamics is then taught in its relation to chemical equilibrium. The course finishes with chemical kinetics and rate laws. The content is similar to that in Chem 112A, but advanced applications are omitted to allow more in-class guided active learning.

Prerequisite skills include the following: proficiency with algebraic manipulation of equations and relationships, familiarity with solving multistep quantitative word problems, familiarity with unit analysis.

Chemistry: The Science in Context (6th edition) by T. Gilbert, R. Kirss, N. Foster, S. Bretz, and G. Davies. The electronic version (e-text with access to online animations) is required. A hardback version is also acceptable for supplementary purposes. There will be two copies of the text on reserve in the Chemistry Library after the fall semester starts.

Only the following models of electronic calculator will be allowed during quizzes and exams: TI-30 XS Multiview (preferred 4-line model), TI-34 Multiview (preferred 4-line model), TI-30Xa (acceptable 2-line model), TI-30X IIs (solar 2-line model). Allowable calculators must be four-line or two-line, non-programmable, non-graphing calculators. This policy will be strictly enforced with no exceptions. Acceptable calculators are available from the WU bookstore as well as Amazon, Walgreens, Staples, Office Depot, and other office supply stores.
