CHEM& 161 General Chemistry with Lab I

5 credits

First in a three-course chemistry sequence for science and engineering students. This course introduces fundamentals of chemistry, including matter and measurement, the structure of atoms, periodicity and the electron structure of atoms, ionic and covalent bonding, mass relationships, and chemical reactions. Includes laboratory investigation of these topics.

Prerequisites: One year of high school chemistry or CHEM& 121, and concurrent enrollment in MATH& 141 or placement into MATH& 142.

Quarters Offered: Fall

Student Outcomes/Competencies:
