Grades on the final & grade in the class.
Period 6  AP Chemistry UPDATED
Ch 20 Assignment Notes
As I worked through this assignment, I found ideas to "skip" and ideas on which to concentrate. "Skip" means, if you read an idea and it is confusing, don't spend too much time trying to understand it.  Mr. Groves
 Concentrate on Entropy. Be able to look at a chemical change and state whether the entropy is increasing or decreasing. (See bullets on pages 916918 for the clues.)
 Concentrate on calculating the entropy change (ΔSº) of a reaction given the entropy values (Sº) of the elements and compounds in the reaction (much like Hess's Law).
 Concentrate on Table 20.2 so you can state whether a reaction is reactant or productfavored.
 Note that "productfavored", "spontaneous", and "thermodynamically favorable" are the same thing.
 Skip the idea of Entropy of the System vs. Entropy of the Surroundings vs. Entropy of the Universe.
 Skip the Three Laws of Thermodynamics.
Finals Week
No Extra Session on Sunday (1/19) or Monday (1/20)
Get a head start on Ch 20 Thermodynamics by watching three videos and reading Ch 20 pages 910924.
After reading pages 910924 (Sections 20.1 & 20.2) you should be able to...
 Define Entropy
 Relate entropy to a sample of particles in a container.
 Compare the entropy of CH_{3}OH(l) & CO_{2}(g) using Table 20.1. Explain.
 Compare pairs of substances in Table 20.1 and explain their relative entropy values.
1) Try Exercise 20.2 (page 919).
2) Look at Equation 20.1 (page 920) and study Example 20.1 (page 921)
3) Try Exercise 20.3 (page 921)
4) Study Table 20.2 (page 923)
5) Try Exercise 20.4 (page 924)
Expect a Practice Quiz on Wednesday.

 Titration Curves for Weak Acids & Strong Bases
Handout:
Homework: Carefully Read Section 18.4 (Titration Curves). After reading 18.3 you might want to watch the ChemTours Tutorial: Buffers. It is a good visual of buffers, but is more effective after you really understand what buffers are. So, if it doesn't make too much sense, come back and watch it again later. You might also want to watch the ChemTours Tutorial: Weak AcidStrong Base Titration. Again, this might seem confusing and will make even more sense later.

 Buffer Calculations
Handouts:
Homework: View the Online Tutorial (Mr. Groves) about Buffers. Study for Friday's Quiz. Read Section 18.3. Pay attention to the idea that some solutions resist pH change (buffers). This quality comes from the fact that these solutions have an acid and a base that do not neutralize each other. Make sure you understand the calculations shown.
Monday November 18, 2013
Since we will not have the Chapter 18 Test until AFTER Thanksgiving Break, expect a QUIZ on Friday November 22, the last day before the break. This quiz could include questions about
