CHM 100 FALL 2000

READING GUIDE #2

The purpose of these reading guides is to help you as you approach each chapter. We will not be covering all of the chapters or every page of the chapters that we do cover. Each student is expected to read before coming to class. These guides will also list the hand-in and study problems for each chapter.

Wednesday, September 20, 2000and Friday, September 22, 2000

Read Chapter 3. This chapter has some fundamental chemical concepts that will be used the rest of this term. There is also a section on the development and history of chemistry. The history of chemistry is interesting, but I want you to concentrate on the concepts. Know what an atom is-also the three fundamental parts of the atom. Can you use the law of Multiple Proportions? This chapter introduces allotropes and isotopes-note the difference. We also start working with compounds. Work with the law of Definite Proportions. Atomic weights, molecular weights and moles are essential to our study this term. Once we have the building blocks we will study chemical reactions. Separation, Synthesis and Analysis are all activities that chemists must understand. Tools of separation that are mentioned include distillation, recrystallization, and chromatography. Spectroscopy is a fundamental tool for following reactions and separations and is a tool of analysis. Can you distinguish between chemical and physical changes? Is there a relationship between chemical reactions and energy? We will introduce scientific notation.

Read Chapter 4. Note the features of the Modern Periodic Table-Periods, Family: Location of Metals, Non-Metals, and Inert (noble) gases. Study Figure 4-17 on page 106. You should be able to answer questions 3 -16 on page 109. I will not make you hand these in, but All would be good quiz or test questions.
