CH101 General Chemistry, Fall 2022, Boston University

Lecture topics and assigned problems

In this semester we cover McQuarrie et al., chapters 1 through 14. A PDF with the detailed (tentative) schedule of lecture topics that will be covered in each MWF and TR lecture (including pre-lecture video assignments that are due can be downloaded here: Detailed Lecture Schedule (updated: 21 October 2022).

The requried homework problems assigned for each chapter will be listed below:

These are the end-of-chapter Problems.
While these will not be collected, these problems will prepare you for the assessments in the course (quizzes and final exam). Solve these problems in your course notebook.
Answer to most of the even-numbered problems are in the Appendix at the back of the book
We also recommend working through the in-chapter Examples and Practice problems as you're reading through the sections in preparation for lecutre

The lab schedule is posted on Blackboard under Lab Content.
