Quiz 1 will assume you
1) have read chapters 1 and 2
2) have memorized Tables 2.3, 2.4, 2.5, 2.6, 2.7 and 2.8
3) can answer problems similar to the blue problems in chapter 2
4) can write a short paragraph (3-8 sentences) in answer to the following:
Several interesting stories (descriptive chemistr, historical discussions)
are presented in Chapters 1 and 2 of your textbook. Select the one that you
found presented material new and interesting to you, briefly summarize the story,
and state what you found new and/or interesting. You may type this paragraph
and bring it to the class. It should be your own paragraph. Group activity IS
NOT acceptable for this essay.
Quiz 2 may include
1. Calculation of averages and standard deviations and expressing the answer
to the CORRECT number of significant figures. Download
a Word document of the handout in class on Sept. 1.
See the rules on-line.
2. Application of the "rules" for significant figures found on page A13-A15
of the text book.
3. Problems similar to 1a and 1b from MEK homework 1. Links to the answer are
on the Homework page.
4. Problems similar to the "blue" problems in Chapter 3 numbered 19, 21, 23,
27, 29, 31, 35, 37, 39, 41, 45, 47
5. Problems similar to the "black" problems in Chapter 3 numbered 24,
Quiz 3 will assume you can
1. Recall from memory the solubility rules given in Chapter 4
and as expanded in class.
2. Write complete, balanced equations including subscripts (s, l, g, aq) from
a description in words of a reaction (you MUST know the symbols and formulas
from Chapter 2).
3. Predict the products of precipitation reactions based on an application of
the solubility rules. The set given below were taken from General Chemistry
by Whitten, Davis and Peck, 5th Edition.
4. Balance oxidation/reduction equations (memorization of some method is required,
but you can choose the method. The method I use was given in class. You can
download a Word document of both the redox rules
and the solubility rules.
5. Identify limiting and excess reagents and calculate theoretical and actual
yields given the masses of starting materials. Or variations on this theme.
In general you should be able to solve ANY stoichiometry problem on the level
of those in chapters 3 and 4 given the appropriate data. This includes calculations
using molarity and density.
6. Assume you can solve problems similar to the "blue" problems in
Chapter 3 numbered 49, 51, 53, 55, 57, 59, 67, 73, 85, 97 and Chapter 4 numbered
13, 15, 19, 25, 27, 29, 31, 37, 39, 45, 51, 53, 55, 57, 59, 61, 67, 75, 77,
81, (87 OR 89)
Quiz 4, recitation moves, final exam time
The CHEM 221 final is scheduled for Tue Dec 14th 3:30pm in BIOL 5. I will
not change the time for any student without a request to do so from the appropriate
Dean.
Quiz 4 will assume you can answer questions similar to those in Chapter 12
numbered 21, 23, 31, 33, 35, 49, 51, 53, 55, 61, 63, 65, 67, 69, 71, 73, 75,

Exam 1 will be handed out at 7:45 am. It will include all of the topics announced
for Quizzes 1, 2, 3 and 4 and all material covered in lecture and laboratories
1, 2, 3 and 4. Although propagation of error will NOT be included, the correct
expression of significant figures for averages and standard deviations will
be.)
The Chapters covered are 1,2,3,4,12.
Additional problems from Chapter 12 are 79, 81, 85, 89, 91, 99, 101, 109, 119.
