Tuesday, 3/27/2012
- From Chapter 8, we have focused on identifying types of reactions (combination, decomposition, single replacement, double replacement, and combustion) and on balancing chemical equations.
- In-Class Activity on Equations.
- The Mastering Chemistry assignment for Chapter 8 is now due on March 31. You will not find much from Chapter 8 on Exam 2. You will be able to display your equation balancing and reaction identifying skills on Exam 3 instead.
- We will also spend some time during today's class on review for Thursday's exam.
Thursday, 3/22/2012
- Mass composition data (grams or percent) to chemical formulas (empirical, then, when molar mass data are available, molecular formulas).
- Here is a worksheet (not an assignment) that we'll spend some time on in class today.
- Here is today's in-class activity.
Tuesday, 3/20/2012
- If you want more practice problems, look at this Review Sheet for Exam 2.
- We started Chapter 7 in today's class, and went through some basic "nuts and bolts" calculations of the type that we'll be using throughout the rest of the semester. Grams to moles, moles to molecules, molecules to atoms, moles to atoms, and percent composition calculations.
- Here are the practice problems from the Whiteboard (Photo1, Photo2, Photo3, Photo4) that you did during the last half-hour or so of class. This was not a graded activity, but you should know how to do each of these problems. Answer key will be posted shortly.

- Quiz 2
- Lewis structures, molecular shapes, and polarity.
Tuesday, 3/6/2012
- Slideshow (Handout), and information sheet on chemical names. We'll review nomenclature today and begin to get into electron dot diagrams (Lewis structures) for covalent compounds.
Thursday, 3/1/2012.
- Chemical names - Stock system (using Roman numerals), polyatomic ions (in ionic compounds and in acids). Learn the patterns, then make sure you know the polyatomic ions listed in the book. There's absolutely no need to learn any of the Roman numeral possibilities. You can figure out the charge on a metal in a formula based on the charge on the negative ion.
- In-Class Activity - See photos: Part 1, Part 2
- Take-Home Activity - This is a repeat of the assignment that you did in class, but now you get more time to complete it and check your answers. Don't use the Internet until you've figured out the names or formulas with your notes first. If you just look them up online, you probably won't learn things quite as well. Your higher score will count for both completed assignments. Due next Tuesday at 2:20 pm.

- Planning to do many more examples today. We can go over the problems that I suggested from the end of the chapter, the in-class activity from Tuesday, and/or the examples on this slide show (and handout) that you'll see today. The more of these that you try before Thursday, the better. If you're taken a shot at a problem, even if you haven't quite solved it, then you'll get more out of my explanations when I talk about them in class.
- We've talked about every type or problem except percent problems. I'll show you some hints on solving those today.
- Prior to next Tuesday's quiz, take a look at the Exam/Quiz rules and get to the point where you can do unit conversion problems on your own. I'll provide you with all of the conversion factors that you'll need, and you will have to know how to you use them to get correct answers.
Tuesday, 1/31/2012
- Today's class is about measurements, how precise they are, how we record them, and how we convert from one unit to another.
- This is a slideshow (and corresponding handout) that I'll go through during the first half of the period. You will also be working in groups on an in-class activity that you'll get during class and which will be due before you leave.
- If you want more practice, check the "web links" link above. There you'll find several additional practice problems, with answer keys. Make sure you can do unit conversion problems on your own. If you want more practice, just ask.
- Here is the Thinking Metric handout that you got today.
Thursday, 1/26/2012
- Today, we went through the metric system and suggested some US-Metric conversions that you should know. We also talked about the various types of volume units.
- This worksheet shows the problems that I did on the board. We got through the first seven problems plus a couple of others that were not on the worksheet. We will continue with this worksheet next week. This is not an assignment; it is merely for reference so that you don't need to rewrite the questions in your notes.
- There are two Mastering Chemistry assignments due on Monday night. Please let me know if you have any questions or difficulties.
Tuesday, 1/24/2012
- Welcome to Chemistry 100 - Fundamentals of Chemistry
- This is today's Math Review activity that you completed in class.
- This is the Keynote Presentation that I showed today in class. It is in PDF format and may be accessed in two forms:
- Slides - one slide per page for better viewing online
- Handout - six slides per page for more efficient printing
- The following two items from the textbook publisher are designed to help you get onto Mastering Chemistry for the online homework:
- Mastering Chemistry First Day of Class Handout (you got this today in class)
- Mastering Chemistry First Day of Class Slide Show (downloadable)
- Here is the "Syllabus Quiz" homework assignment that is due on Thurs, Jan 26.
- This is an extra credit homework assignment ("First Day Questionnaire") that is due on Thurs, Jan 26.
- Note: Homework assignments (sometimes called "Take-Home Activities) are always due at 2:20 pm on their due date, regardless of your arrival time.
