The Course Website Is broken! (for now)

Chem 101A is the same course taught by a different instructor (Gretchen). You can use that website for now. (Ignore specific dates though.)

Section BDJ Your location information is not

online, as of yesterday. Here it is: Lab: 201 Chem Annex Discussion: 19 Noyes Lab If you didn’t make it to lab as a

result, touch base with your TA so they know that you are in the course.

Textbook Homework Page 10 of your lab manual has a list

of problems. These correspond to end-of-chapter problems in the textbook.

Chapter 2 and 3 are due tomorrow in discussion. You will turn them in and your TA will grade for completion. Showing work is a good idea.
