 REMINDER: THIS ICE WILL TAKE PLACE ON WEDNESDAY, 1/27/10 - NOT TUESDAY 1/26/10

There will be specific questions related to Chapter 2, but most of the ICE will be on Chapter 8. You will have to use the principles of dimensional analysis and sig figs correctly to do the Chapter 8 problems.

Conversions to and from scientific notation Using dimensional analysis to make conversions from one unit to another. (You are expected to know the metric prefixes we have covered in class and how to do conversions in unfamiliar units if the conversion factors are given to you.) Stating the number of sig figs in any number Using the rules of addition and subtraction correctly. Using the rules of multiplication and division correctly.

Define the term "mole." Find molar masses of elements and compounds. Convert from atoms/molecules to moles and vice-versa Convert from mass to moles and vice-versa Convert from atoms/molecules to masses and vice-versa Find the percent composition of a compound Distinguish between empirical formulas and molecular formulas Given percent composition, find the empirical formula of a compound Given percent compostion and molar mass, find the empirical and molecular formulas of a compound
