Week 16

Friday, 12/19

•  Thermodynamics Unit Test

WednESday, 12/17

• Today will be our day for review!  I would recommend doing one more set of five problems of your choosing as part of your review work.

Monday, 12/15

• Do the Heats of Formation Guided Learning

Week 15

Friday, 12/12

• Today we'll spend a bit of time reviewing with a practice problem that used to be a short quiz in the middle of the Thermo unit. 

• I don't have an official new problem set for this week.  I'd like you to be preparing yourself for the Unit Test.  I recommend that you dig into the two chapters (5 and 19) that we have been working from and pick 3-5 problems for yourself.  You can focus on specific sections from the chapters that you'd like more practice on, or dig into those problems waaay at the back of the exercises that really mix content together (much like the AP Tests do!).

WednESday, 12/10

• Today we'll wrap up entropy and discuss free energy and how it relates to the equilibrium constant.

• Homework is to dig into the AP Practice and MC assignments.

Monday, 12/8

• Today we'll go over the Solutions Unit Test and will spend a bit more time with Entropy.

Week 14

Friday, 12/5

• Today we'll be working through some of the introductory notes on Thermodynamics.  We'll focus on the different ways that we can calculate the energy changes that accompany a chemical reaction.

• Homework is from the book: Read 19.1-6 (you need to really read these sections...there is more depth than what we covered in Gen Chem) do problems 1, 11, 29, 41, 57b and c, 71 

WednESday, 12/3

• Today we'll play the Enthalpy Costs Card Game for a bit.  Remember that we have several ways to determining heat of reaction.  Bond energy is an important one to think about! 

• We talked about three ways to calculate heat of reaction: Bond energies, Hess' Law, and Heat of formation.  We'll take a bit of time today to really look at how those are all actually just doing the same thing.  

Week 13

TUESday, 11/25

• Heat of Combustion Lab. --this write up will be due next week on Wednesday. Everyone should do their own write-up.

• Homework is from the book.  Re-read through sections 5.5-8 and do exercises 12, 67, 77, 87, 117.

Week 12

FRIDAY 11/21

• Today we'll get going with Thermochemistry!  Thermo starts in AP with remembering how evergy changes happen and how they are described.  We'll spend most of the time, here at the beginning of the unit, looking at enthalpy.  

  • • We can figure out the enthalpy change for a chemical reaction in several ways: bond energies, heats of formation, and Hess' Law.  We'll take a look at a reaction today and work through each of these three methods for determining the heat of reaction.

    • We'll also talk about a lab method for measuring heat: Calorimetry.

    • Next class we'll be doing the Heat of Combustion Lab. Read through the lab instructions and do the pre-lab before you come to class. 

• Homework this week two things:

  • Read Chapter 5 do exercises 6, 43, 47, 55

• Thermo AP Test Practice Problems 

• AP Multiple Choice Practice #6

Wednesday, 11/19

• Solutions Unit Test!--We'll get going on this test at the beginning of class and then use the last half hour of the class period to start into the notes on Thermo.

Monday, 11/17

• Today is a day for work and review.  We'll work on some practice problems together and you'll have some work time to wrap up.  Come to class today with your questions based on our bookwork and AP Practice work and we'll get all of those questions sorted out.

Week 11

FRIDAY 11/14

• Today will be mainly work time.  Make sure you are getting ready for the unit test that we'll have on Wednesday of next week.  

• Homework for this week is some continued practice from the book: Ch 17 exercises 55, 57, 73; Ch 13 exercise 93.

Wednesday, 11/12

• Today we'll do some continued practice with Le Chatelier's Principle and how it is applied to our solution equilibrium.  We'll spend some more time with ICE tables, especially as they apply to complex ion formation.

• We'll also take a look at how volumes can be affected when two liquids are added together.  

Week 10

FRIDAY 11/7

• Today we'll clean up any notes that need finishing from yesterday's class and you should have a bit of time to work on your AP Practice work.

• Homework is Ch 17.1, 4-7 do exercises 9, 67  Also, for some more IMAF practice do Ch 11 exercise 75

Wednesday, 11/5

• Today we will take a look at some practice problems with solubility equilibria. It will likely be most useful to dig into the work that you did for the Ch 17 bookwork. Be sure to have all problems attempted and come with questions that came up as you worked. ICE Tables are extremely important to be able to use in many AP Chemistry problems. We will take some time today to make sure that everyone is comfortable with using them.  

• We have already used an ICE table to determine what the molar solubility is for a compound based on its Ksp.  We'll remind ourselves of LeChatelier's Principle from Gen Chem and see how that works out mathematically on an ICE table in two ways:

  1. • 1. 1. Common Ion Effects

          2. Complex Ion Formations

     • You should dig into to AP Practice and MC work to see what you can do with those problems now that you can use an ICE table!

Monday, 11/3

• Today we will be wrapping up the Beer's Law Lab. You have some solutions prepared and may need to make or remake some too.  Today's focus though will be getting the absorbance data collected from the colorimeters.  

• The QC concentration of "nickel (II) sulfate" is 0.152M.

• You'll need to have Graphical Analysis loaded on your chromebook.  If it isn't already there, you can use THIS LINK to go to the site to load it onto your school google account. 

Week 9

Wednesday, 10/29

• Today we will be doing the Beer's Law Lab. Come to class with the pre-lab questions wrapped up and an idea for your plan of attack!  This lab will use the solutions and dilutions info we have talked about in class.

• The QC concentration of "nickel (II) sulfate" is 0.152M.

• You'll need to have Graphical Analysis loaded on your chromebook.  If it isn't already there, you can use THIS LINK to go to the site to load it onto your school google account. 

• Homework is the bookwork that was assigned last week AND:

• Since you have a nice long weekend coming up, I'd like you to dig into the bonding topics a bit more. The most obvious way to get a bit more practice is with the AP Practice and MC practice problems. You should work on those! I will also have a few options for Guided Learning Activities for you to pick up in class (I'd like you to do at least two of the four available):

1. Types of Bonds

2. Polar and Non-Polar Molecules

3. Properties of Covalent Bonds

4. Mass Spectroscopy

Monday, 10/27

• Today we will be getting started on the Beer's Law Lab.  

Week 8

Friday, 10/24

• Today we'll talk about solubility equilibria. This will connect some concepts about solutions to some of the equilibrium ideas that we worked on when you were in General Chemistry.

• Homework is from the book: Read 17.4 do exercises 51 and 53

Wednesday, 10/22

•  Bonding Unit Test!  

• Today we began the Solutions Unit.  We'll spend some time thinking about how we should be thinking about modeling a solution, remembering some vocab from Gen Chem and getting comfortable with how we can use a balanced chemical equation to describe a solution.

  • We will also review the process of making solutions of a specific concentration both from a concentrated stock and from mixing a solid solute into a liquid solvent.

• Homework is to read 13.1-4 do exercises 3, 15, 25, 47 (This HW will be collected with the work from next week.)

• Solutions AP Practice Problems

• AP Multiple Choice Practice #5

Monday, 10/20

• Today we'll wrap up any loose ends and do some practice with thinking about bonding and intermolecular forces.  

• Homework is to wrap up the AP Practice and MC #3 assignment because the test is next class!

Week 7

Friday, 10/17

• Today we'll wrap up our work with hybridization.  We'll practice drawing hybridization in bonded structures like ethene.  Remembering resonance as a phenomenon that we saw in Lewis Structures in Gen Chem, we'll be abel to see a mechanism for this movement of bonds!

• Homework is to wrap up the bookwork from last class.  Also, this is a great time in this unit to dig in to the AP Practice and MC assignments for the Bonding unit.  The unit test will be next week!

Wednesday, 10/15

• Hydridization will be the focus of our work today. We need to reconcile our observations of molecular geometries with our understanding of electron orbitals...hybrid orbitals will do that for us. We will also discuss how we can be a little more refined when we talk about how atoms are bonded together.

• Homework is from the book: Read 9.4-6 do exercises 5, 47, 51, 55  and Ch 8 exercises 87, 95  

Monday, 10/13

• Today we'll wrap up the Molecular Models Lab that we started last week.  This lab should be turned in individually this week on Wednesday.

Week 6

Friday, 10/10

• I imagine that we'll have some cleaning up to do with topics from earlier in the week.  We'll use today for that work!

Wednesday, 10/8

• Today we will look at electronegativity, VSEPR, and IMAF.

• Homework is from the book: Read 8.6-8 and 9.1-3 do exercises 8.57, 83 and 9.27.  

  • • • Exercise 8.83 doesn't have an answer in the back of the book for some reason.  You'll have to check the answer key in the classroom.  

• VSEPR Geometries Table--Make sure you fix the errors on the side with the diagrams of the different geometries!

• We will have a bit of time at the end of class to dig into some practice with this material via the Molecular Models Lab.

• Later on, we will be discussing the major new topic for this unit. To prepare for our look at orbital hybridization and bonding, take a look at Ch 9 sections 4 through 6. Seeing the diagrams and just doing one quick pass through will introduce you to the vocabulary for this topic and will make the discussion in class more efficient and effective!

Monday, 10/6

• We'll begin the Bonding Unit today. We'll talk about the three main types of bonding: ionic, covalent, and metallic. For ionic bonds, we'll need to think often about their crystal lattice structure. The energy of bonds is also going to prove to be an interesting subject during this unit and we will start by looking at the energies of ionic structures with a look into Lattice Energies.

• Homework is from the book: Read 8.1-2 do exercises 21 and 27-- Also make your six flash cards for practicing the different types of bonding.  

  • • Flash Card Evaluation Rubric

• Today we'll take a look at how we can use light to measure energy changes for electrons with the Atomic Spectra Lab. This lab will be due on Wednesday next week.

Week 4

Friday, 9/26

• Today we'll look at a specific method for collecting data about Ionization Energies. The method is called Photo Electron Spectroscopy (PES). This is something that is specifically mentioned in the AP Curriculum but the cool thing about it is that there are a bunch of different tests that chemists use that work on the same principles. Today, we'll look at some data, learn how it is collected, and start to think about what it tells us.

• Units Test for Atoms, Molecules, and Ions AND Atomic Theory/Periodicity will  be next week.  Make sure you are getting wrapped up on the two sets of AP Practice and MC Practice problems.

• Homework for Week 4 is due today: 

  • Ch 2.  Do exercises 11, 25, 39, 73, 99

WednEsday, 9/24

• 1. 1. 1. • You'll hopefully remember a bit about Periodic Trends (remember Zeff???) from Gen Chem. They will be the focus of our notes for the day.

           • This unit we will be covering Atomic Structure and Periodicity. We'll start today with a look at the quantum model of the atom and some of the evidence for it. We'll largely be starting out by thinking about light. Then we'll move some of those ideas that we can use to describe light over to describe matter and particles.

• Homework for today is from the book.  You have already skimmed through Ch 2.  Do exercises 11, 25, 39, 73, 99

  • If you already have logged into the College Board site, use the same login info...DON'T make a new account for each course!

  • Get signed up and logged in and register for the AP Chem Test!

    1. 1. • • Today we will be doing the Millikan's Oil Drop Experiment Lab.   This lab write-up should be done individually and is due next week on Wed.

Week 3

Friday, 9/19

• Today we will start with a reveiw of some proficiency topics from Gen Chem.  When we work with electron configurations, there are a few things we steered clear of and exceptions that we didn't address.  That was great for Gen Chem but we need to be able to deal with those realities.  We'll take a look at those today.

• The majority of the day will be a the Empircal Formula Guided Learning.  How do we know what the chemical formula is for a compound.  What does that measurement look like and how do we analzye the data?  You'll find all of that out today!

• Homework is to wrap up the Guided Learning if it wasn't completed in class. 

• Next class we will be doing the Millikan's Oil Drop Experiment Lab. Read through the lab instructions and make a data table in your notebook before you come to class on Mon.  With the last lab, there were lots of questions that showed that folks hadn't read the instructions beforehand.  Make sure you are coming to lab periods prepared for the lab.  

HW for Week 3 is due at the end of this week:

• Chapter 2 Exercises 4, 8, 19, 79, 101

  1. • Ch 10.4-6 do Exercises 10.7, 10.9a&b, 10.61, 10.85 

wednEsday, 9/17

• Today we will review some old info on Atomic Structure and take a look at some of the experiments that were done to help develop our understanding of the make-up of the atom.

• We'll also spend a bit of time today looking at some patterns in acid names and the names of the ions that they contain.  Knowing this pattern will help you feel familiar with naming and formulas without making you feel like you need to MEMORIZE every single polyatomic ion.

• Homework: Read 2.1-7 (just skim through them...it is likely mostly pretty familiar), be super awesome at the naming in 2.8. Do Exercises 4, 8, 19, 79, 101

• Determining the Molar Mass of a Volatile Liquid--individual write-up is due today.

• AP TEST PRACTICE-- These two practice assignments will be due with the unit test.  There are practice problems from Gases here so you can see what those look like.  The others are asking you to write BCEs and then answer a question about the reaction.  Look at those and do what you can...but they cover a lot of material that may feel a little rusty or unfamiliar.  In the cases where you feel like you don't know how to answer the BCE and/or follow-up questions, just make sure that you can write out any of the names from formulas or formulas from names!  

  • Multiple Choice Practice Assignment #1

  • AP Test Practice Problems 

Monday, 9/15

• Gases Unit Test!

Week 2

Friday, 9/12

• We'll wrap up notes on gases today. We should have a bit of time in class to work through some practice problems and answer any questions.

• Homework: Read 10.4-6 do Exercises 10.7, 10.9a&b, 10.61, 10.85 

• The unit test for Gases will be on Monday!

Monday, 9/8

• Today we'll wrap up some notes from last week, and dig into some of the handy consequences of the things we learned about gas relationships and the ways that gas particles are moving around.  

• We'll cover a few important things to think about when you are working on homework for AP Chem.

• We have our first lab next class: Determining the Molar Mass of a Volatile Liquid.  Be sure to have read the instructions before you get to class on Tuesday.  Think about what things you'll need to have as data in order to answer the lab's main question.  Getting a rough draft data table ready to go is  a great way to prep for a lab.

Week 1

Friday, 9/5

• We are going to start AP with a unit that we don't touch on much in General Chemistry but one that is pretty intuitive based on your prior experiences.  Good or bad, we've all had plenty of experience with Gases! 

• Homework for tonight is from the book: Read 10.1-3, 7 do Exercises 3, 17, 27, 37.  The answer in the back of the book for problem 37(a) is incorrect, you should get 5.15x10^22 molecules.

• We'll do our first lab on Tuesday next week.  Read through the instructions for Determining the Molar Mass of a Volatile Liquid and start thinking about what data you need to collect.  Come to class with a data table ready to go!

Wednesday, 9/3

• Welcome to AP Chemistry!  We have gotten a lot of new exciting things to try this year in class.  

• We'll jump right in with a homework assignment.  This one is a Review Worksheet of content from Gen Chem that I am sure is already a part of your soul...we'll just dust it off a bit after the summer break! :)  It is OK if things are a little dusty but we should work on things if it is!

  • 1. Please fill out this Google Form to tell me a little about yourself.
