CH101 General Chemistry, Summer 1 2024

http://genchem.bu.edu/ch101-summer1-2024/schedule.html

(Tentative) Course Schedule

In this semester we cover McQuarrie et al., chapters 1 through 14. The tentative schedule for the course is posted here.

Please note:

  • The listed Pre-lecture videos are linked on Blackboard and are due by 9am on the posted day. These videos are designed to effectively help you prepare for lecture.
  • Each of the lecture topics has the corresponding chapter or section(s) from McQuarrie, Rock, and Gallogly (MRG) General Chemistry 4e listed. Reading through the sections, and Working through the in-text examples, before lecture is an excellent way to prepare for class.
  • Discussions are every Monday, Wednesday, and Thursday at 9:30am in your assigned room.
  • Lab topics are listed below. Additional details about the labs are posted on the Blackboard site under Lab Content.

Important note about Chapter 10:
  • We are skipping chapter 10. Much of the way the material in chapter 10 is presented is very outdated (at best), or even outright wrong. For example: total ionic equations are totally incorrect (see what we did there?). Instead, we will only discuss net ionic equations in this course.
  • While this book is just the right level for CH101/102 and does most things great, chapter 10 is not good. Please do not use the text of chapter 10 to guide your work. Also, most of the YouTube videos out there also teach this outdated and wrong material.
  • We will cover select topics (not all of them!!) related to chapter 10 as we work through chapters 11 and 12. Please use the pre-lecture videos for that material (videos 10.1 – 10.5) as well as the material we will present in class.
  • We will make use of a few of the reference tables from Chapter 10, a few in-text examples, and some of the end-of-chapter homework problems.
  • Note: our focus of chapter 10 will be on developing a microscopic understanding of the following types of reactions: dissolving solids, precipitation reactions, acid-base reactions, and reduction-oxidation reactions.
  • Please see the important note about this in the detailed pathway through chapters 10-12.
