The Final Exam

The CH141 exam will be on Monday, 12/17 at 1:30 -4:30 PM.   We will use the same Keyes first floor classrooms for the exam.   You may work for the entire 3 hours, but the exam is expected to take most students 120 min.  The exam will cover all class and laboratory materials and we will use the same format as the hour exams.   Allowed exam items are pens/pencils and a course-approved calculator. You will be provided with a periodic table and equation sheet.   You may bring snacks and a water bottle.

There will be an optional review session on Sunday, 12/16 in Keyes 105 at 4 PM.

There will also be office hours from 1-2pm Monday, 12/10 through Friday, 12/14.  On Monday and Tuesday Prof. Madison will be in the Chem Help Center (Keyes 104). On Wednesday through Friday, come to her office (Keyes 314).

Practice exams are posted on our web page.  The Final Exam Equation Sheet is available as well.

 

Week 14 Schedule: Section B

In our last week of classes we will be building on our understanding of intermolecular forces to investigate why solutions have the properties that they do.  Why are some solids insoluble while others readily dissolve? Why do cold beverages stay carbonated better than warm ones?  How can we use properties of solutions to make frozen ice cream?

Homework #12 is due on Wednesday.  Additional practice problems will be posted on Mastering Chemistry to give you a chance to practice the material covered in chapter 13.

Monday Lecture Material: Lecture Slides 12-3Class notes 12-3
