Read the text, p.251-257, including example problems.  Note the steps to follow in solving problems, on p.256 in margin.
Homework:  p.254 #23-25; p.258 #30ac; p259 #7

The unit test is on Tuesday, Nov. 23.  Review questions include:  p.30 #7-9; p.170 #2; p.193 #3, 7, 13de, 14ac, 17ce, 22, 31; p.229-231 #5, 7b, 8, 11, 14, 14, 19, 20, 25, 29; p.271-273 #5, 6, 9, 13, 15

You usually have more of at least one ingredient in your house than is needed to make a recipe.  This ingredient is in excess.  Sometimes you barely have enough of an ingredient to make a recipe.  This ingredient is your limiting ingredient because it limits the amount you can make.  Consult the text p.251-252, and if you were absent today, do the "ThoughtLab" on p.252.  Answer the questions on the handout.  Answers are in brackets.  These questions are available on the unit 3 page of the grade 11 section of this site under the title "Limiting Reactant Problems".

Before we went to the game, lab reports were handed in and each person chose a problem to work on according to how they felt about mole calculations: 
need to work on basics  - p.194 #15
confident  - p.230 #18
need a challenge  - p.231 #28

Read p.241-248 for help with this concept.  Homework:  p.244 #11; p.246 #16, 17; p.250 #4

You can change relative amounts of recipe ingredients to make different amounts of food.  In the same way, you can change relative amounts of reactants or products in balanced equations.  See the text p.234-240.
Homework:  p.238 #5, 6; read example problem p.239-240 then answer p.240 #8, 9

The instructions for the experiment are on p.226-227.  For the Discussion of the lab report answer #1, 3, 4, 6-8 on p. 227.  The lab report is due on Friday.

We had our mole calculations quiz today.  If you were absent, you will write it when you come back.  The text reference for today's lesson is p.223-225.
Homework:  p.225 #23-25; p.228 #6; Read the experiment on p. 226-227 and make a hypothesis (see Prediction, p.226); the observation table should have a stir rod included in the masses.

Empirical formula is found from experimental data and is the lowest terms formula of the compound.  Molecular formula is the actual compound formula without having the subscripts reduced to lowest terms.  The text reference for today's work is p.207-218.  There is a quiz on Monday that counts for marks on mole calculations.
Homework:  p.209#10; p.211 #15, 16; p.214 #3; p.218 #17-19

We had a practice quiz on mole calculations.  It is on the Unit 3 page of this site.  If you missed class, read the text p.198-205.  Note the Law of Definite Proportions. 
Homework:  Answer p. 201 #1; p.204 #6; p.205-206 #3-6

No class.  Enjoy your day.
