Assignments and topics for next week (see the Course Schedule)

- The Unit 1 Exam (see below)
Unit 1 Exam
The Unit 1 exam will cover the topics of
- Acid Base Review
- Common Ion and Buffer Solutions
- Acid-Base Titrations
- Solubility Equilibria
The exam will be available Saturday Feb 5 at 8 am and must be completed by Monday Feb 7 at 11:59 pm. You can access it on D2L by clicking Assessments then Quizzes. (D2L calls anything it grades automatically a “quiz” – including graded homework or exams).
Even though you have a three day window in which to take it (which hopefully will give you some flexibility), it will be timed with a 2 hour limit. You must complete it in one 2 hour sitting, so arrange to take it when you have 2 hours and will not be interrupted.
If you took CHEM 151 online at LCC, you likely remember having to submit your work for the 8 point questions in a submissions folder in D2L after taking the exam. The 152 exams are set up differently and you will not be required to do this. If you don’t know what I am talking about, don’t worry about it!
There are resources for study and review (including review questions and a practice exam) in addition to the lecture notes and text. Click here for a list of additional study and review resources for Unit 1.
Let me know if you have questions!
