Final Test Review Key

Below is the key for the revies for the final test. Remember, the final test will consist of the molar mass determination lab practical and a 14 question multiple choice section. You will collect data with a lab partner during the lab practical, but perform the calculations for the lab and answer the multiple choice questions by yourself.

Quiz Reminder and Tie-Dye Announcement

Remember, tomorrow, May 5th, 2010, you will be having a quiz covering the heat of fusion / vaporization worksheet and the heat of fusion lab. All questions will be written. All equations will be supplied for the quiz.

We will be doing the annual chemistry tie-dye lab on Friday, May 14th. You are not required to do the lab. The cost for those that want to do the lab is $4.00. The $4.00 will go to cover all costs for the lab. The dyes are really expensive. Please pay Mr. Brueckner the $4.00 in class as soon as possible. You must also supply the item that you want to tie-dye. White cotton items work the best. You will be given a hand out and instructions on the day of the lab.
