This course provides an introduction to chemistry for those students with little or no high school chemistry. Students will be introduced to concepts fundamental to studying matter at the molecular level. Principal topics include introductions to the nature of atoms and molecules, stoichiometry, solubility rules and equilibria, gas laws, chemical equilibrium, acid-base reactions, periodic relationships, chemical bonding, molecular structure, intermolecular forces, oxidation-reduction reactions, and related applications. Laboratory work comprises a system of qualitative analysis and quantitative techniques. The course provides preparation for further study of organic chemistry, biochemistry, physical and inorganic chemistry and is intended for students who are anticipating professional study in chemistry, in related sciences, or in one of the health professions, as well as for those students who are interested in exploring the fundamental ideas of chemistry as part of their general education.
Format: lecture/laboratory; pre-recorded lectures, two hours per week; recitations, two 75-minute meetings per week (in-person or remote); laboratory, one 2-hour lab per week (in-person or remote)
Grading: yes pass/fail option,
no fifth course option
frequent electronic and written weekly problem set assignments, laboratory work and analysis, quizzes, two tests, and a final exam
Students are required to take the online Chemistry Placement Survey prior to registering for the course (chemistry.williams.edu/placement); incoming first-year students are required to meet with a faculty member during First Days.
first-year students; students who have studied chemistry for one or more years are directed to CHEM 153 or 155
CHEM 151 may be taken concurrently with MATH 102--see under Mathematics; CHEM 151 or its equivalent is a prerequisite to CHEM 156; one of CHEM 151 or 153 or 155 required for the BIMO concentration
This course fulfills the QFR requirement with regular and substantial problem sets in which quantitative/formal reasoning skills are practiced and evaluated.
