CHEMISTRY: God bless you as you study! Here’s our overview of the test from 7th period today and a look at some chemical names and formulas and oxidation numbers. Did you find the Chapter 7 Stuff to Know sheet? Be sure and use it as a road map for your studying. I know it seems like a lot, but you can do it!

First priority – make sure that you have memorized EVERYTHING. Then, practice!!! First – go to the post from today about the Ch 7 Online Review WS on Canvas. Be sure and read very carefully the instructions for it!

You can re-practice with the Physics Classroom as a guest, sciencegeek.net and make sure you can write and name chemical formulas. Practice, practice, practice!!! Then start practicing the different kinds of problems – do at least three of each one of them. And also try those on sciencegeek.net. That’s always some good practice. And don’t forget about polymers!

I’ll be praying for you! You can do it!!

CHEMISTRY: You’ve finished the chapter, now it’s time to practice what you’ve learned – and there is A LOT! To do that you’ll be doing the Ch 7 Online Review Worksheet on Canvas. (Click on Quizzes and then Practice Quizzes.) There are 44 total questions, but 6 of them are problems to work out. You can have two attempts on the worksheet and your grade will be the average of your two scores. It’s due Saturday by 11:59 PM.

CAUTION: Read the following IMPORTANT instructions before you begin – your answers won’t be accepted if you don’t type them in a certain way. And don’t forget you’ll have to turn in written work for the problems.

IMPORTANT #1: READ BEFORE STARTING. To type in your answers, make sure of the following. If you get an answer wrong because of the way you typed it, I won’t go back and change your grade.

• Capitalization – don’t capitalize any thing EXCEPT symbol letters that are supposed to be upper case. So don’t capitalize names for elements or compounds.
• Roman numerals – DO put a space between the element name and the Roman numeral and CAPITALIZE I and V. Like this: titanium (IV) oxide
• Ion charges & oxidation numbers – You don’t include ion charges when you write formulas, but YOU DO write charges if you are writing the formula or oxidation number for an ion. Don’t put a space between the number and the charge. Like this: +2
• Units – Put a space between a number and the unit. Write the symbol, not the word for the unit.
• Double check your spelling!!
• You can have 2 attempts on this assignment. Your final score will be the average of your two scores

IMPORTANT #2: For the problems section, work the problem correctly and completely on notebook paper and turn in the notebook paper in class. You won’t receive credit for the problems if you don’t turn in your work. FYI – there are 6 problems.
