Summary for Week 6 (September 23 - 27)

AP Chemistry

• On Monday/Tuesday students did a laboratory experiment on precipitation reactions. I also taught about the concepts in section 4.3 of the textbook (acids and bases).
• On Wednesday/Thursday I taught about net ionic equations for acids and bases and several concepts related to oxidation - reduction reactions
• On Friday students took a quiz on net ionic equations and oxidation-reduction.

Honors Chemistry

• On Monday students practiced balancing equations.
• On Tuesday students did a lab experiment on preparing solutions.
• On Wednesday I taught about classifying chemical reactions into one of six categories: synthesis, decomposition, single- and double- replacement, combustion, and neutralization
• On Thursday students did a lab experiment on chemical reactions and took a quiz on balancing and classifying chemical equations.
• On Friday students took a practice test for Unit 3.

Summary for Week 5 (September 16 - 20)

AP Chemistry

• On Monday/Tuesday students took a Test on Chapter 3.
• On Wednesday/Thursday we discussed the behavior of substances in water (electrolytes and nonelectrolytes). We used the solubility rules to determine if an ionic solid is soluble or insoluble. We practiced writing net ionic equations for double replacement reactions.
• Today students took a quiz on Chapter 4, sections 4.1 & 4.2
• The homework for Chapter 4 is available on my Google Drive. You can find it by clicking here. It covers section 4.3 of the textbook. It is due on Monday/Tuesday. I will be sending out an e-mail this weekend with some important tips about how to complete this homework.

Honors Chemistry

• On Monday students took a Test on Unit 2.
• On Tuesday I introduced the concepts associated with Unit 3, including classification of matter and phase changes. We also talked about separating mixtures, with examples that included chromatography, filtration, and distillation. We saw that electrolysis can be used to decompose water into hydrogen gas and oxygen gas.
• On Wednesday we worked on classification of matter and conservation of mass.
• On Thursday we discussed how to calculate the molarity of a solution. Practice problems included how to calculate the grams of solute needed to prepare a certain volume of solution in which the molarity is known.
• Today I reviewed molarity problems a bit more. Students took a quiz on Matter, Changes, and Molarity. The homework for Monday is a worksheet on Balancing Equations.
• If you missed class for any reason, please go to my Google Drive to see notes from class and get copies of worksheets that you missed. E-mail me if you have any questions.

Students can look in the AP Chemistry folder or the Honors Chemistry folder to find important documents. Have a good weekend.

Summary for Week 4 (September 9 - 13)

AP Chemistry

• On Monday/Tuesday we discussed limiting reactants and the Chapter 3 Practice Problems.
• On Wednesday/Thursday we did an experiment on calculating empirical formulas using a hydrate salt and a reaction between copper and sulfur.
• Today I went over the answers to the Chapter 3 Practice Test.
• The Chapter 3 Test is on Monday/Tuesday.
• The homework for Chapter 4 is due on Wednesday/Thursday. This homework will be collected and graded for correctness.

Honors Chemistry

• On Monday I gave a quiz on Mole Conversions.
• On Tuesday we did an experiment on the decomposition of potassium chlorate and calculated the percentage of oxygen by mass in this compound.
• On Wednesday we discussed percent composition and empirical formulas. I gave a quiz on those topics.
• On Thursday we discussed how to calculate empirical formulas from percent composition data.
• Today I went over the answers to the Unit 2 Practice Test.
• The Unit 2 Test is on Monday.
