CHEM+10H++CHAPTER+2+ICE

Because of days missed, we will change the pre-vacation ICE to a quiz on sig figs only - to take place Wednesday, January 6, 2009.

The Chapter 2 ICE will cover the same material as was covered on the quiz with the addition of performing mathematical operations while keeping the correct number of sig figs.

Specifically:

Conversions to and from scientific notation Using dimensional analysis to make conversions fro 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.)

Giving measurements with the correct number of sig figs if you see a picture of a measuring device in use (like the graduated cylinder question)

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.
