ChemProfJH
Concise, clear chemistry lectures and lab experiments with a focus on Allied Health General, Organic, and Biological Chemistry (GOB) courses. Lecture notes are organized to show how concepts and problems connect to each other, and some labs are designed to be done and/or watched at home as needed. Videos specifically support CHEM 3 at Long Beach City College, but I hope everyone finds them useful!
