AP Chemistry Summer Assignment 2014

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 three 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.
  1. 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:

  • Be able to use the Unit Factor Method to convert from one quantity to another
  • Report answers to the correct number of significant figures
  • Include the correct units with your answer
  • 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.

  1. 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.

  1. 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:

·  Describe and explain early atomic experiments, state the conclusions

  • Memorize charges, formulas and names of common mono and polyatomic ions in tables 2.3, 2.4 and 2.5
  • Name and write formulas for

Ø  binary ionic compounds like sodium chloride

Ø  binary ionic compounds like iron(III)sulfate

Ø  hydrated ionic compounds

Ø  acids

Ø  binary covalent compounds

  • 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.

  1. Complete the attached Name and Formula worksheet. Put your name on the worksheet. You will turn this in.
  2. 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.

7. Read chapter 3 with emphasis on the following topics.

·  The mole

·  Empirical formulas

·  Writing and balancing chemical equations

·  Calculating amounts of reactants and products

  1. Do the following problems on a sheet of lined paper. Put your name on the paper. You will turn in this assignment.

Chapter 3, pp. 123-128 11, 15, 17 a, 21, 26, 36 c, d, 42, 54 b, c, 62, 66
