AP Chemistry

Week 4

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

- - - - 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
Homework this week is also the next two AP Practice assignments:
- - - - Multiple Choice Practice Assignment #2
        Atomic Theory and Periodicity AP Test Practice Problems

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

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 Wednesday!

Today we'll work on the Determining the Molar Mass of a Volatile Liquid Lab. This lab write-up will be due, individually, on Wed next week.
Homework for Week 2 is Due at the end of this week:
- Ch 10.1-3, 7 do Exercises 3, 17, 27, 37

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.

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!

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!
