CHEM 3CGeneral Chemistry
The third course in UCSC’s three-quarter introductory chemistry series. Topics in this quarter include the first and second laws of thermodynamics, redox reactions, electrochemistry, phase changes, and physical properties of solutions. Course consists of in-person lecture, a secondary active learning discussion section, and a secondary laboratory section. In addition to the lecture, students are required to enroll and attend one discussion section and one laboratory section.
Prerequisite(s): CHEM 3B.
- This class replaces the old CHEM 3C and CHEM 3CL (prior to fall 2026) with a single class that includes the lecture, lab, and discussion section in a single enrollment. If you register for this class, do not register for CHEM 3CL, as you will get the lab portion of General Chemistry via CHEM 3C.
