This calendar lists topics by chapter.section number of the OS text. You will find more information including links to videos and my comments by going to the corresponding resource page on this website. For example, topics for 8/30 are shown as "1.1-1.2". You should check out the "Ch01 Resources" page for more information. (Links to these resource pages can be found in the drop down menu.)
You will find due dates for assignments in the Chem101 program. In general, you can expect a class prep assignment before every class, and weekly problem sets due on Mondays.
