Welcome To AP Chem--2020 Edition! 

• Woo!  What a start!  Good thing we are a tough and resilient bunch!  

• This week we'll still be able to meet online through either Zoom or Google Meet.  You all are my first class of the day so I'd like to try Zoom first and use that if it works.  I think it will!  But if it doesn't then we'll make the switch to Google Meet.  If you can, log in to your CSD509j Student account in Google before trying these links.  

  • • Zoom: https://csd509j.zoom.us/j/93938894347?pwd=UDQ2enpUcE9SR0gxRGUyVmg1T0Zadz09   --  If you can't get into your student google account, send me an email and I'll send you the code you'll need to get in.

    • Google Meet: https://meet.google.com/jtn-nhqe-dnu?hs=122  

Wednesday, 9/9/20

• 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!

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

Thursday, 9/10/20

• 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 10.1-5, 7, 9 do problems 4, 13, 27, 41, 83

• If you haven't gotten your book yet, you can use these photos I took of mine! :)  You'll need to be logged into your Student Google Account or they won't open.  

Friday, 9/11/20 

• 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.

• Unit Test will be next week on Tuesday

• Homework: Read 10.6, 8 do problems 7, 58, 63, 85 (a and b), 108

• Homework for Week 1 is Due Today:

  • Read 10.1-5, 7, 9 do problems 4, 13, 27, 41, 83

  • Review Worksheet

Below this is last year's page.  I want to keep using it so it is still here. :)

Google Meeting:  (this Week's Meeting 6/16 @ 10:00am-11:00am)  

I'll just leave this up here at the top of the site because we can just reuse this link each time we meet:  https://meet.google.com/jtn-nhqe-dnu?hs=122  

Here are the answers to the Organic Chemistry Review assignment:  Page 1      Page 2

Online School Week 11--The last one! (June 15-19 )

• You will need to be able to use (but do not need to memorize!) the table of alpha-amino acids 

• We'll go over any questions that you have from last week's work.

  1. Naming straight or branched chain hydrocarbons 

  2. Recognizing/Drawing Functional Groups

  3. Review for Organic Unit 

• Since we are looking like next year might be utilizing a bit of online/distance learning (we really just don't know what things are going to look like!), I'd like to pick your brains a bit about what things, from my class or others, have worked well or not so well with all of this!

Online School Week 10 (June 8-12 )

• This week we'll take a look at two kinds of reactions: Reactions of ethene (and other alkenes) and polymerization reactions with an emphasis on protein synthesis from amino acids. 

• You will need to be able to use (but do not need to memorize!) the table of alpha-amino acids 

• You should focus on three things this week: 

  1. Naming straight or branched chain hydrocarbons 

  2. Recognizing/Drawing Functional Groups

  3. Review for Organic Unit--(A hint for number one, a hydrocarbon that looks like a stop sign would be called cyclooctane) You'll be able to do all of this assignment by the end of this week.  Working on it a bit at a time and doing what you can should be a good approach for the week.  Some of these are not simple...don't let that discourage you!  Remember to use what you do know to figure out what you don't know. :)  Next week when we meet we'll go over questions that have you feeling stuck.  

• I'll check in with all of you about what you want to do for the last few weeks of school and we'll come up with a plan.

Online School Week 9 (June 1-5 )

• This week we'll do a bit of practice and take a look at isomers in some ways that go beyond just branching.  There are lots of interesting consequences to making changes to structures!  On Thursday's class, we'll start into some basic organic reactions.

• You should focus on three things this week: 

  1. Naming straight or branched chain hydrocarbons 

  2. Recognizing/Drawing Functional Groups

  3. Isomer Worksheet--This WS should be done by our class meeting on Thursday so that we can go over any questions that you may have at that point.  

• I'll check in with all of you about what you want to do for the last few weeks of school and we'll come up with a plan.

Online School Week 8 (May 26-29 )

• This week we'll meet only once...but we'll cover the different functional groups that show up in O-Chem.  We'll focus on identifying them and naming compounds...moving forward in college you'll learn how you can make molecules with functional groups in specific locations!

• Some good naming practice can be found here and I bet you could find some good websites for practicing functional groups with a quick google search!

• This is another site I found with good practice for naming lots of organic compounds....you can really pick which parts you want it to quiz you on. http://nomenclature101.com/nom/en/index.php   (I really like this one but would recommend that you just do it with pencil and paper instead of trying to type answers and check...it's overly picky!)

• Your HW this week is (AGAIN!!!) to email me a selfie of you doing one of the two practice websites above (or with your flashcards in whatever form they may take!)  This week, you should be adding the functional groups into your studies.

Online School Week 7 (May 18-May 22 )

• Our Monday meeting this week will just be an opportunity to chat.  Sometimes it is nice to take a moment and debrief the AP Test questions.  This one is totally optional...If I don't see you that day I want you all to know that I am really proud of the hard work that you have done.  Double proud because of how you had to really find your own motivation to dig in and study in a way that previous runs of AP students just haven't had to deal with.  This is a tough course with a hard test and coronavirus didn't make it any easier...but you are totally BA and took on the challenge in a really cool way!  

• On Wednesday I'd like to see everyone because we'll start digging into our Organic Chemistry Unit which will round out the AP year by making it more equivalent to what you would be covering in first year college chem courses. Learning Organic Chemistry is kind of like learning a new language and today we will start into the topic by looking at the nomenclature that we use to describe organic compounds. We will also talk about the different groups that organic compounds get sorted into.

• Later you can practice identifying functional groups with a partner and/or work on naming practice. Some good naming practice can be found here and I bet you could find some good websites for practicing functional groups with a quick google search!

• This is another site I found with good practice for naming lots of organic compounds....you can really pick which parts you want it to quiz you on. http://nomenclature101.com/nom/en/index.php   (I really like this one but would recommend that you just do it with pencil and paper instead of trying to type answers and check...it's overly picky!)

• Your HW this week is to email me a selfie of you doing one of the two practice websites above (or with your flashcards in whatever form they may take!)

Online School Week 6 (May 11-May 15 )

• AP TEST ON THURSDAY!!! :)  Be sure you are logging in to the test using your E-ticket by 10:30am!

• You don't need to come to every Google Meet this week (unless you want to!) but I would like to see everyone at least once either on Tuesday's or Wednesday's meeting.  I want you to let me know that you have seen your ticket and are ready to go.

• AP Test Practice:  A lot like last week!  But now you want to be focusing on all of this between now and Tuesday.

  • Do some more of the FRQ Long Essay practice questions.  All of the ones that I have checked out look pretty good!

    • • I would recommend that you do something to time yourself for each question.  Remember that you'll have 25 minutes for your first and 15 for the second.

      • Check your answers and reflect on mistakes.  Don't beat yourself up for making a mistake...it happens.  Think instead about what clues or resources you could have been using or ways to help yourself avoid silly mistakes in the future.  

      • Consider the college board's wording on answers involving explanations.  It is worth a bit of effort to try to mold our explanations to be similar to theirs.  

      • Remember to try a few ways that you think may work for you to take the test: Computer, phone, etc.  Find out what you like and what is a pain in the neck!

Online School Week 5 (May 4-May 8 )

• AP Test Practice: 

  • Do FIVE more of the FRQ Long Essay practice questions.  All of the ones that I have checked out look pretty good!

    • • I would recommend that you do something to time yourself for 20 min per question.

      • I would recommend that you don't do all five in one sitting...spread that practice out.  I think one or two problems four or five days each week until the test would do nicely for your preparation!

      • Check your answers and reflect on mistakes.  Don't beat yourself up for making a mistake...it happens.  Think instead about what clues or resources you could have been using or ways to help yourself avoid silly mistakes in the future.  

      • Consider the college board's wording on answers involving explanations.  It is worth a bit of effort to try to mold our explanations to be similar to theirs.  

      • Remember to try a few ways that you think may work for you to take the test: Computer, phone, etc.  FInd out what you like and what is a pain in the neck!

• Electrochem:

  • Electrolytic Cells--Which half reactions are the ones that will happen?

  • Homework is from the book: Read Ch 20.5-8 do problems 7, 9, 51, 65, 73.

• You should be pretty well prepared to start digging into these now.  I might suggest that you do the AP Practice backwards because the older problems are definitely a little weird...good weird...but weird.

• Multiple Choice Practice #11 -- MC 11 KEY 

• Electrochemistry AP Practice Problems --  AP Practice KEY -- 1971

Online School Week 4 (April 27-May 1)

• AP Test Practice: (I don't know that my links will work so you may need to go find the problems in the set of practice "essay" questions.

  • Do this practice FRQ before Tuesday's class: Units 3, 2, 4 FRQ: Long Essay Question

    • I would like you to do the entire question written by hand and then try to do the answer submission by uploading a photo in AP Classroom.  I want us to try to figure out any problems that you might run into while we are just doing practice work.  If it doesn't work to submit it through AP Classroom, send your photo to my email.

  • Do this practice FRQ before Thursday's class: Unit 5 FRQ: Long Essay Question

    • This one will feel at the beginning like it is something you don't know.  In fact, it feels like it is a topic that is specifically stated as not being tested in AP Chem.  Don't let that get under your skin...you can use what you do know to figure out what you don't.  That should be your mantra! 

• Electrochem:

  • We will continue with voltaic cells and start to look at spontaneity, non-standard conditions, and electrolytic cells as time allows. 

  • Homework is from the book: Read 20.3-4 do problems 4, 25, 37, 41, 43.  (I know this was on last week's work but we didn't get to it on Wednesday so I pushed it into this week) :)

• Multiple Choice Practice #11  

• Electrochemistry AP Practice Problems

Online School Week 3 (April 20-24)

• Review using AP Classroom Units 6 and 7  

  • I would hold off on the "Essay" questions until next week.  Don't worry if you've already done some.  I would like to give you a bit of advice and I'm going to make an "assignment" for next week out of them.

  • College Board FRQ Scoring Guides:    Unit 6      Unit 7

  • My work:    Unit 6 --MC and FRQ    Unit 7--MC and FRQ

• We'll continue this week with Voltaic (aka Galvanic) Cells.  This will make sure that everyone got the correct info out of the Applet assignment from last week.  

• Homework from the book: Read Ch 20.3-4 do problems 4, 25, 37, 41, 43

• Let's see how the start of the week goes...I may add another Redox/Electrochem thing for our second meeting like we did last week.  

• Multiple Choice Practice #11  

• Electrochemistry AP Practice Problems

Online School Week 2 (April 13-17)

• Review using AP Classroom Units 4 and 5  

  • College Board FRQ Scoring Guides:    Unit 4     Unit 5

  • My work:    Unit 4     Unit 5 MC     Unit 5 FRQ

• We'll start the Redox unit with a bit of review of material from Gen Chem and then will expand on that with work on balancing redox reactions (in acidic and basic solutions). 

• Homework is from the book. Read 20.1-2 do problems 1, 13, 15, 17, 23.

• A huge part of how redox chemistry impacts our lives is that it is the chemistry of batteries.  There is enormous variety in the ways that batteries function.  I want you to re-familiarize yourself (this assignment is one that you may remember from Gen Chem) with some simple batteries using the Voltaic Cells Applet and the Demonstration of a Voltaic Cells Worksheet.

• Multiple Choice Practice #11  

• Electrochemistry AP Practice Problems

Online School Week 1 (April 6-10)

• • Last Weeks AP Practice Problem Work:  1970 and 1984  

  • Review using AP Classroom Units 1-3   (Have a good chunk of this attempted by our Google Meeting time on Tuesday!)

    • EVERYONE should definitely do the FRQ practice at the very least.  You should also do all of the MC practice on the site as well unless you have a super compelling reason to skip it.  The AP test will be only FRQ but doing a whole bunch of MC practice too will cover a wider variety of content and that will be helpful for getting ready.

    • My Answers: Unit 1     Unit 2     Unit 3    

    • Scoring Guides: Unit 1    Unit 2    Unit 3

  • If you have other resources for practice, I would really encourage using those.  More practice is a good way to make sure you are ready...there really isn't any practice that is bad.  If you find one that you think is particularly good, please share it during our meetings during the week!

AP TEST INFORMATION!!!!

• • Just released this morning!  The AP Chemistry test is going to be Thu, May 14 at 11:00am.

    • You'll need to get logged in half an hour before to get all set up.

    • The test will be open note/book...not open amigos. 

    • There will be two FRQ questions that you'll do one at a time.  One will be 20 minutes, the other will be 15 minutes.

    • College board has talked to universities and is confident that AP test scores will be awarded credit "as they have in the past." I also heard an admissions counselor on NPR yesterday saying that they are well aware of what we are dealing with and are prepared to keep this all in mind as we do applications next year and as the new Freshman Class comes to campus in the fall.  

Google Meeting--April 2 @ 11:00-12:00

You may need to use your non-school account to access the meetings for now. 

Spring Break!

I've gotten a few questions over email and I want to make sure that everyone hears a few things.  Unfortunately, right now the answer to your questions is "I don't know yet."  I am hoping that we'll be able to get as much figured out right after spring break as possible.  It looks like you may have more info on the changes to AP Tests than I do right now...I just read a much less detailed message from the college board so I'll be digging into their info for teachers over the next week or so.  

Tests, test dates, and dropped scores and all of that will depend on what the rest of the year pans out like for us.  My goal is to have things be as "normal" (haha!) as possible.  I bet that will involve some online instruction.  I think that we'll be getting information about how the district wants us to do that in our next staff meeting on 3/30.  My primary goal for AP Chem is to get you all ready for college so I'll keep aiming in that direction.

I usually tell AP students to take a nice break from chemistry over spring break...you should still do that!  If you have Acid/Base HW still undone, you should get going on that on March 30 and 31.  That way we'll have a good place to start from on April 1...whatever that ends up looking like.  

We are now officially on Spring Break and I want you to treat it like the break that it is!  We'll roll with whatever gets thrown at us when we get back in April!

You guys are the best!   

Mr. Kanter  

Coronavirus Closure Week-ish

• No official work to do over the rest of the month...but I do have some advice!

  • Finish your Sheets file that you would use to input data from Standardizing NaOH with KHP (which is monoprotic and has a molar mass of 204.22 g/mol).

  • Go through the Multiple Choice Practice #10 and Acids/Bases AP Test Practice.  

  • Work together over your apps/phones/computers in ways that work for you.  Chemistry can be a good way to connect with your friends while we are all doing social distancing!

  • We'll do a bit of review before we take any kind of tests so don't worry about coming right back to an Acid/Base test. :)

  • Stay safe!  Wash your hands!  I'll see you all in a few weeks!

Wednesday, 3/11/20

• Today we'll wrap up any notes on topics that we missed or need to revisit some more.   We need to understand buffered systems and how salts play a role in acid/base chem.

• Homework is from the book: Read 16.9-10 do problems Ch 16--77, 83, 91, 104 Ch 17--86, 90

Week 26 Monday, 3/9/20

• Today we'll focus on BUFFERS! Buffers can get confusing so we'll really be looking at how we can organize our work when dealing with them to make our lives a little simpler. We'll also talk about salt solutions, chemical structure of acids and titrations. It is wise to go through the reading for this topic before you come to class today.

• Homework is from the book: Read Ch 17.1-3 do problems 4, 7, 15, 23, 27, 41

• I will make adjustments to the assignment for the NaOH Standardization Lab.   You won't need to write up anything specifically for that lab.  Just set up your sheets or excel file to turn in.  We'll add the error analysis for that lab into the lab we'll do next week.

ThurSDAY, 3/5/20

• Later in this unit we will need to use sodium hydroxide in the lab. In order to use NaOH, we will need to standardize the solution to determine it's concentration. There are no instructions for this lab...you will get to make all of the decisions. The write-up will be a little different too...just calculations and error analysis:

  • Calculations--I would like you to create a spreadsheet in Excel that will do all of the calculations for you. With your group, you should use Excel to program a spreadsheet that you can plug in any pertinent data and it will spit out the concentration of the NaOH you are trying to standardize. You will need to make sure that it is clearly labeled so that I can use it with my test data to check it. Don't worry...I will start today's class with a look at how you can program excel to run calculations for you.

  • Theory--You'll need to write up an explanation of why it is necessary to run this standardization to determine the concentration of NaOH to determine the concentration even though I can just calculate the concentration of most solutions that I make. Remember that NaOH is a "hygroscopic" compound. Feel free to come in and chat with me if you have ideas but need some help sorting though them!

  • Error Analysis--This is important even if you have the program running calcs for you. 

    • How did your error affect your result--is the true value a bit higher or lower than your experimental value?

    • How could you improve your process to reduce error. 

• Assignments DUE today:

  • Determination of the Equilibrium Constant for Iron Thiocyanate Lab

  • Homework Packet Week 4

    • Ch 16.1-8 do problems 3, 13, 31, 39, 45, 61

Week 25 TUESDAY, 3/3/20

• If you still need to turn in the Equilibrium Lab you should have it all done and turned in by Thursday at the latest!

  • A few notes:

    • • Procedure should just reference the lab instructions unless you deviated from them significantly. 

      • Theory should have a discussion of using Beer's Law to determine the concentration of the test samples, using Le Chatelier's Principle to know the concentration of the compounds we were looking at, and using the concentrations to find the equilibrium constant.

      • Calculations and Results section should answer the questions on the back of the lab.

• Today we are going to start in on Acids and Bases. Most of today's info is a refresher of material covered in Gen Chem. We'll really start digging in deeper with next week's notes. 

• Homework is from the book: Read 16.1-8 do problems 3, 13, 31, 39, 45, 61

Wednesday, 2/26/20

• The test for this unit is on Friday. I'd like to use our extra time this week whenever we have some to go over some of the practice problems that we've done. We'll have some time in class today to work on some of our practice, especially AP Practice problems or a few extras from the Integrated or Marathon Problems.

• Homework for today is from the book: Review Ch 15 do problems 71, 80, 87, 91, 97. Small rounding differences can lead to big changes in final answers. You will want to be careful on this one but you may also be able to look at your work and see that everything is fine and rounding was your only problem...that is ok too!

Week 24 Monday, 2/24/20

• Today we'll be doing the Determination of the Equilibrium Constant for Iron Thiocyanate Lab.  Come to class prepared!

  • • A few notes:

      • Procedure should just reference the lab instructions unless you deviated from them significantly. 

      • Theory should have a discussion of using Beer's Law to determine the concentration of the test samples, using Le Chatelier's Principle to know the concentration of the compounds we were looking at, and using the concentrations to find the equilibrium constant.

  • You should expect the Kinetics Unit Test to be Wednesday of next week.

Week 21 TuesDAY, 2/4/20

• Today will be a great day for cleaning up any notes that we have not quite completely finished. My idea is to go over the integration of the first order integrated rate law and to take a quick look at changing base as it applies to finding reaction rate orders. Neither of those two topics are absolutely critical to the work we do in this class. If you have other clarifications that you'd like to have taken care of we can use our time today for that as well.

• Homework is from the book: Read 14.7 do problems 85, 105, 109, 115, 122

• I'd also like everyone to pick three to five problems from Chapter 14 to do some additional practice in any area that you'd like. Of the three to five, please choose one from the "Additional Exercises" and one from the "Integrative Exercises." (These will be due with Week 2 HW)

• Homework is from the book: Chapter 3 problems 107a, 109; Chapter 4 problems 99, 106, 112.

• This is a short unit...the unit test will be next class!

Week 10 TuesDAY, 11/5/19

• Today we will revisit a number of old and familiar topics. This unit should feel like review so we'll spend more time during this unit looking at application in the laboratory and working with practice problems to see how stoich fits into an AP level question.

• Next class, we will be doing the Determining the Empirical Formula of Copper Iodide. Read through the lab instructions before you come to class on the day of the lab. You should come to class that day with a data table prepared for the lab. I should be able to tell from the data table alone that you know what the procedure for the lab is asking you to do. This lab will be our first formal lab write-up and we'll talk a bit more about what that means on the lab day.

• Homework is from the book: Read Chapters 3 and 4 in their entirety....just skim through parts that you are familiar with but read more carefully through the material that seems less familiar. Chapter 3 problems 69, 77 and Chapter 4 problems 19, 24, 25. 

• AP Multiple Choice Practice #4

• Stoichiometry AP Practice Problems--I actually want you to have this done sooner than usual this unit. I recommend doing two of the problems with today's bookwork set and the other two with next class' set.

Week 7 TuesDAY, 10/15/19

• 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 problems 17, 19, 26, 27, 81.

• Homework is from the book: Read 6.5-9 do problems 49, 59, 61, 71, 76.

Week 5 TUESDAY, 10/1/19

• The next unit we will be covering is 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 is from the book: Read 6.1-4 do problems 2, 29, 33, 35, 43a, b, c.
