Announcements

In order to give people adequate time after the holiday to work, I have reset a number of homework assignments to new due dates.  Check the assignment list below for new due dates.  Note that the semester is rapidly closing, and we are in crunch time.  There will be one more assignment set posted Monday that will be due on Friday, the day of your test.  Since all of this homework is preparation for that test, it is strongly suggested that students compete homework sets as much in advance of the test as possible.  In the meantime, enjoy your day of rest and Happy Thanksgiving.  (11-27-08, 1:00pm)

The following homework assignments have been posted and are due on 12/2: 9.1b - Acids and Bases , 9.2b - Acid and Base Strength , 9.3b - Bronsted-Lowry and Conjugate Acid-Base Pairs , 9.4 - Equilibrium Position in Acid-Base Reactions , 9.9e - Titration (11-25-08, 3:30pm)

Chapter 10 PowerPoint slides are now posted.  (11-24-08, 2:20pm)

If any student had difficulty accessing the Ch 9 & 10 practice problems, it should be fixed now.  (11-23-08, 10:00pm)

The handout listing the acid and bases to memorize has been posted.  (11-23-08, 10:00pm)

The following homework assignments have been posted and are due on 12/1: 8.6d - The Equilibrium Constant , 8.6e - Equilibrium Constant Calculations , 8.6g - The Significance of the Value of K , 8.8a - Le Chatelier's Principle: Concentration, Temperature , 8.8b - Le Chatelier's Principle: Pressure, General.

I will be collecting on last set of extra credit homework problems from the Chapter 9 and 10 practice sets on Wednesday.  I will post the key for that set immediately afterwards.  (11-22-08, 12:00pm)

A handout for on the concept of normality and titrations has now been posted.  We may not have time to cover this material in depth during lecture time, but it will be on your fifth exam.  Consider it an out-of-class assignment to read this handout.  There are some additional practice problem at the end of the sheet, similar to the ones already in the Chapter 9 and 10 practice sheet.  (11-22-08, 12:00pm)

The key for the redox reaction handout is now posted.  (11-22-08, 12:00pm)

The key for the fourth exam is now posted below.  (11-21-08, 11:30am)

The redox reaction practice sheet that was posted on the 12th should be regarded as your homework assignment for practicing assigning oxidation numbers.  OWL does not have an assignment for this.  I will not be collecting these sheets for a grade.  I will be posting a key for this sheet so that you may check your own work shortly.  (11-17-08, 11:00am)

I have posted a set of homework problems which will be due 11/24:  8.3b - Activation Energy and Energy Diagrams, 8.4b - Factors Affecting Reaction Rates. (11-18-08, 11:00am)

I have posted a set of practice problems for Chapters 9 and 10.  (11-17-08, 3:45pm)

I have posted a slightly updated version of the Chapter 9 powerpoint slides.  (11-12-08, 2:30pm)

The Gas Laws and Concentration Practice Problems Key is posted below.  (11-11-08, 10:30am)

A chemistry tutor, Melissa Hayes, has been hired by the Academic Support Center.  Melissa's hours in the lab will be:  Monday 1 pm - 3:30 pm, Tuesday 8 am - noon,  Friday 1 pm - 5 pm,  Saturday 9 am - noon  (10-29-08, 9:00am)
