-
Chemistry students ALWAYS forget how to enter things in properly on their calculator! This shows you how to:
1) enter in values in scientific notation
2) do longer calculations with multi-step conversions (proper use of parenthesis)
-
This website does offer tutorials for solving all types of common high school chemistry problems. Mr. Johnson has his own video tutorials for everything, but this site does have a catalog of tutorials and examples that might prove useful if students need a different source for seeking help.

This video discusses the following questions: How do we measure items in science? When we see numbers, what kinds of information does that communicate? What are significant figures all about?
-
-
This assignment is due 7:30 am on _____ (the day of the test).
-
Chapter overview - It's long because it goes over everything. Use the bookmarks tab to go to the sections you need, and know that I go into more depth with significant figures, doing math in scientific notation, and metric system conversions in other videos above. Turn to those for a better, specific understanding of those concepts.
-
This PENCIL & PAPER TEST will be on _____ around 9:20 am. Â
-
Section 3
-
-
Use the conversion factors printed on the back page of this worksheet to arrive at the correct answer. Be sure to round your answers to the correct number of significant figures, or the problem will be marked wrong! Some problems require as few as two steps; others will require up to 8 steps. (And no, you will NOT need to know these conversions on the test. This is just an exercise to get used to the "feel" of how we approach conversions using a dimensional analysis technique)

Watch your significant figures!

This is the lab sheet that provides the scenario and the information to complete the lab.
To complete this lab, you need to fill out the form that is below the video. Â
For writeup, I would like EACH student to:
1) fully describe your procedure so that ANYONE can follow it and get the same results
2) list your unknown # and identify the powders in them - remember that the first two vials had 2 powders and the 3rd vial (labeled S2) had 3 powders in it. I need to know the vial number with your answer in order to grade it!
3) Provide a conclusion that defends your conclusions. Tell me, as if you were on a witness stand, how you arrived at your conclusion based off of your observations. I want to see why you are certain that vial #23 contained powder A and powder C (for example).

VSEPR assignment - part 1 File
This is a screen shot of the answers to problems 1-7 on the top half of your sheet to ensure you are doing the Lewis structures correctly
-
Fill out the first 7 problems on this worksheet AFTER watching me work through a couple of problems in Part 1 of the video. Then, once you have done 1-7 I want you to check your answers and you are now ready to watch Part 2 of the video to see how I want you to do the 2nd set of problems 1-18. Once you have done that (it will be messy!), you are then ready to watch the videos I have created that walk you through how to actually solve the problems AND gives the notes for this chapter as you go.

Explanation & notes for problems 1-8 - cannot access without watching "Step 2 video" then completing the problems Interactive Content
This video serves as the notes we traditionally take in class for this chapter. I typically use the work done from the problems 1-18 to generate an understanding of terminology and/or concepts for this chapter. Be sure to have completed the work for the introductory problems 1-18 before taking notes from this chapter! The lecture is broken up into 3 parts: this first part covers problems 1-8. Be sure to take notes on these key terms/concepts!

-
Draw, give the name of the shape & angles, and comment on the polarity of the following problems
-
Assignment: Click on this link to model each of the molecules from the assignment so you can visualize the shapes and angles that are created.

This assignment is due _____.
If you are finding that your answers do not match the options, check for the freezing point constant (water is 1.86, but benzene is 5.12) and also go back and check your multiplier for the dissociation particles. Remember that molecular compounds (nonvolatile) act as only 1 particle, the ionic compounds are the only ones that split up and act as separate particles. Refer to the video tutorial for more in-depth learning on that - starts at 50 seconds in. You can resubmit your homework if you messed it up the first time!
