Introduction
Welcome to AP Chemistry. You have had one year of high school chemistry. In order to effectively cover all the material in AP chemistry, we have to move quickly through material you are already familiar with. To get started, I am asking you to work through the first two chapters of our textbook this summer. You should already be familiar with all the assigned material. I recommend that you do this work in August so that it is fresh in your head when we begin in September.
Assignment
1. Cover your book!
2. Read chapter 1 with emphasis on the following topics.
Section 1.3, The Scientific Approach
Section 1.4, Chemical Problem Solving
Section 1.5, Measurement in Scientific Study
Section 1.6, Significant Figures
Objectives:
a. Be able to use the Unit Factor Method to convert from one quantity to another
b. Report answers to the correct number of significant figures
c. Include the correct units with your answer
d. Distinguish between accuracy and precision
See Sample Problems 1.2 through 1.7 (pages 16-28). Try the follow-up problems after each sample problem for practice. The answers to the follow-up problems are on page 35.
3. Do the following problems on a sheet of lined paper. Put your name on the paper and show your work. You will turn in this assignment.
Chapter 1, pages 35-39, #’s 26-29 (answers to the green problems are given in the back of the book) 31, 47, 55, 57, 59, 69, 74, 78.
4. Read chapter 2 with emphasis on the following topics.
Section 2.2, Early Observations
Section 2.3, Dalton’s Atomic Theory
Section 2.4, Observations that led to the Nuclear Model
Section 2.8, Compounds, formulas, names and masses
Objectives:
a. Describe and explain early atomic experiments, state the conclusions
b. Memorize charges, formulas and names of common mono and polyatomic ions in tables 2.3, 2.4 and 2.5
c. Name and write formulas for binary ionic compounds like sodium chloride, binary ionic compounds like iron(III)sulfate, hydrated ionic compounds, acids, binary covalent compounds
d. Calculate molar masses of compounds
See Sample Problems 2.5 through 2.13 (pages 65-72). Try the follow-up problems after each sample problem for practice. The answers to the follow-up problems are on page 79.
5. Print out and complete this Name
and Formula worksheet. Put your name on the
worksheet. You will turn this in.
6. Do the following problems on a sheet of lined paper. Put your name on the
paper. You will turn in this assignment.
Chapter 2, pages 80-85, #’s 31, 33, 40, 42, 85, 89, 93, 97, 105, 107, 128.
Good luck. Have a nice summer. See you in September.
