Review for your unit test by reading your notes and textbook, summarizing important points, completing and checking review questions, and getting help with the questions that have incorrect answers.

Actual, theoretical, and percentage yield all represent the amount of product in a chemical reaction.  Read p.260-264 in the text for help. 
Homework:  p.262 #31, 32; p.264 #36

Unit test is next Monday.

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 note for tomorrow's class is on the unit 3 page of this site as "yield lesson".
The unit test is on Monday.  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 "Thought Lab" on p.252.  The unit test is next Monday.
Homework:  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".

Read p.241-248 for help with this concept.
The Unit 3 Test will be on Monday, May 2.  Review questions and a topic list are on the unit 3 page.
Homework:  p.244 #11; p.246 #16, 17; p.250 #4

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 Tuesday.

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.  The note used in class can be downloaded from the unit 3 page of this site.
Homework:  p.238 #5, 6; read example problem p.239-240 then answer p.240 #8, 9

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. 
Homework:  p.209#10; p.211 #15, 16; p.214 #3; p.218 #17-19

If you missed class, read the text p.198-205.  Note the Law of Definite Proportions. 
There will be a quiz on the mole concept tomorrow that will be marked.
Homework:  Answer p. 201 #1; p.204 #6; p.205-206 #3-6
