Chapter 1: Problems 17, 18, 23, 25, 27, 29, 30, 32, 37, 38(a,d,e,f), 40, 45, 47, 49, 51, 53, 71, 77(e), 85, 87, 89, 97 + Supplementary Problems (Factor Label Method & Unit Conversion)
Memorize: You must know the name and symbols of the first 36 elements of the periodic table, plus the following elements: Ag, Au, Pt, Hg, Sn, and I. You do not have to know their atomic numbers from memory (you will always have a periodic table), but you need to be able to write the symbol if given the name, and vice versa.

Memorize: You must know the metric prefixes from nano- to Giga-, as given in Table 1.3. You need to know the prefix (nano-), the 1-letter abbreviation (“n”), and the power of 10 (10-9). Memorize: You need to know the relationships between metric units, and be able to convert between them (e.g. kg to g, or oC to K). You do not need to know English units or their conversions to metric, with the sole exception of temperature. You must be able to convert from oF to oC, and vice versa.
