We practiced all of the types of mole calculations, and how to write them with proper format.
Homework:  complete the "Pre-lab Classwork" section of the mole cookie handout (A to G on the back) to hand in on Tuesday - if not handed in, you can't make cookies on Wednesday

We completed the basic mole calculations today.  Look in your text on p.186-192 for examples.  If you were not present in class today, come for extra help - this lesson is crucial to understanding the rest of the course.
Extra help at lunch Monday in room 103.
Homework:  p.186 #27; p.187 #31ab,32a-c;  p.190-191 #35, 37, 39

We discussed how to use units to set up answers to calculations.  The note for this is on the Unit 3 page as "unit ratio lesson".  We performed an activity to discover that mass can be used to count items.
Homework:  p.177 #17, 18; p.179 #5

In chemistry, there is a unit of measure called the mole.  It represents 6.02x1023 of anything, in the same way that a dozen represents 12 of anything. There is a link to a video that explains this on the unit 3 page of the site.  It is called "Avogadro Calculations Video 1". 
Homework:  Read p.176, 178; answer p.177 #13, 14, 16; p.178 #19, 20, 22

Read p.162-165 and summarize the information in your notes.  Read through the handout "Rubber Stopper Isotopes" on the second side of the second significant digits handout, and answer the questions.  Read the sample problem on p.167 and answer p.167-168 #1-4.  Check your answers on p.195.

When using measurements to calculate answers to problems, the number of significant digits in the measured values affects the answer you record.  Consult your text, p.20-22 for help with this. 
Homework:  B&C from Friday's 1st handout; #2 from 2nd handout; text p.22#3, p.24 #4, p.647 #4, 5

We reviewed scientific notation.  A slide show that helps with this is on the unit 3 page of the grade 11 website, and there is more information on p.660 of your text. 
You need to be able to express the result of any calculation to the appropriate number of significant digits for the rest of the course.  Significant digits are all the digits in a measurement that are certain, plus the first one that is uncertain.  Consult your text, p.17.
Homework:  Handout questions A, D, E; and on 2nd handout, #1
Answers are on the unit 3 page in a pdf file.

The chemical reactions unit test was written.
BRING CALCULATORS TO CLASS FROM NOW ON!

Everyone completed an experiment written by another group and suggested how to improve it.
Unit test tomorrow.

The unit test is on Thursday.  Review questions are on the homework blog from October 14
