TEST: HONORS CHEM
TOPICS: Ch 1
Know ALL definitions. The only equations or relationships that will be given are
English/Metric equivalents.
ALL PROBLEMS must show set-ups in an
EQUATION format, with answers in the correct units and with the correct number
of sig figs. ALL CONVERSIONS must be set up as dimensional analysis to receive
credit.
All topics discussed will be tested. The test will consist mostly of short answer, fill-in
the blanks, and problems.
