CHM 1045--General Chemistry I--Fall 2002

What Do I Need To Learn?

The objectives for each chapter are given in some detail at your textbook's companion web site. You will be responsible for being able to work the types of problems done in class and recitation, suggested end-of-chapter problems, and problems on the CAPA homework set.

In addition, from time to time, there will be certain things you will just have to memorize, as you would a vocabulary in a language course. Below I will list these specific things you will need to learn from memory.

Chapter 1
Metric prefixes.
Approximate English to metric conversions.
Chapter 2
Know the names and symbols of elements 1 to 57, plus W, Pt, Au, Hg, Pb, Bi, At, Rn, Th, U, Np, Pu
Knownames and charges on monoatomic ions (Figure 2.8 )
Know names and charges on polyatomic ions (Table 2.4 )
Know names and formulas of acids and salts (Table 2.5 )
Know organic word stems (Table 2.6 )
Know names and structures of organic classes (Table 2.7 )
Chapter 3
Avogadro's Number
Chapter 4
Strong acids and strong bases (Table 4.1)
