April 6 is the projected start date for all your classes to resume learning in some form. I hope that you have followed the recommendations for the work in Chemistry and have got to the point where you can balance redox equations in acidic or basic conditions (notes p. 3-4). On April 6, I will post a practice quiz on balancing and oxidation numbers that you can try (for practice, not marks). Then you can mark it yourself to check your understanding. Then we will be continuing on in the Redox unit.
If you have not mastered Balancing redox equations yet do that during the rest of this week so that you are ready to move forward with us. See my previous post on my website: schieck-chem.blogspot.com to get instruction on how to do that.
If you have any questions about balancing (however minor), please don't hesitate to e-mail me.
My tentative general plan to proceed in Chemistry as of April 6:
1. We will move at a slower pace due to the additional challenge of learning in an on-line format.
2. Check my website: schieck-chem. blogspot.com at the beginning of the week to see what you need to do in Chemistry that week.
2. At the beginning of the week I will try to post a little assessment quiz that you can try and mark yourself (for feedback and practice)
3. Then we will cover 1-2 topics in the week. I will experiment with a variety of formats for delivery and I will give you some practice questions.
4. At the end of the week if there are questions (either conceptual or homework question you didn't understand) please e-mail me by Friday and I will try and address them in some format at the beginning of the following week.
5. We are both figuring this out as we go. I appreciate your questions and feedback (What learning formats work and which don't?)
I know these conditions are not ideal. Do your best. That's all you can do. Reach out to me if there is anything I can help with.
Work for the extended break (March 23-April 6):
a) Finish oxidation numbers worksheet on p. 2 of Electrochemistry Notes
b) Learn How to Balance Redox Equations by using either option A or option B described below. Then do Practice Q on p. 3 of notes ( bottom left: #2, 3, 6, 7)
Option A: Use Posted Redox Class Notes
Read notes p. 3 on balancing by Half-Reaction method Acidic Conditions and Basic conditions, referring to two examples on p. 4 which illustrate the method.
Option B: Watch 2 videos that explain
How to balance Redox equations in Acidic solution -

How to Balance Redox equations in Basic Solution -

(The video method (Option B) used differs slightly from the method described in the class notes (Option A) in two ways:
In the class notes, electrons are added first using oxidation number comparisons, then O and H is balanced at the end of the process.
In the video, O and H are balanced first in each 1/2 reaction, then electrons are added using charge comparisons. These are just superficial differences; use whichever method you prefer.
You do NOT need to cover the Bridge method.
Balancing Redox Equations is Fun!!!- Try it.
Thurs Mar 12:
We wrote the Acids and Bases unit test
