Chemistry 5-1-19 Ionic Bonds

CHEMISTRY: Isn’t this a beautiful crystal of copper sulfate pentahydrate? Since we’ve been talking about crystal lattice structures, I thought you might like to see something different than salt!

Here’s the lecture on ionic bonding and writing equations for ionic bonds. Remember, when you write ionic bonding, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. And make sure you put the dots in the right order!

Lost Inside the Mponeng – The Last Weekend!!!

It’s you last weekend to work, so how’s it going with the Lost Inside the Mponeng Project? Remember, first and foremost this is a CHEMISTRY project. You must talk about all 23 items – why they would be good to use or why you would not want to use them. NEVER ever say, I had no use for the item.

Here are a few other things to remember – it’s a long list to review, but very important, so READ IT ALL! TWICE!

1. Save, save, save, save, save, save, save, to several different places because your computer wants to eat your project!! Email your latest copy to yourself – label it with the date so you’ll know it’s the latest one, or put it in Google Drive or use a flash drive, or Google Dropbox – and use the date thing when you save it. And printing out the latest copy is also a great idea!

2. Your printer and the printer at your parents’ job will die/ run out of ink/ jam/ run out of paper/ explode, etc., so don’t wait until the last minute to print things out. And save, save, save, save, save, save, save, to several different places because your computer wants to eat your project!!

3. Make sure you make printed copies of the sources each source you use. Copy the page that you use and highlight the portions that you use. Print front and back to save paper and space! Staple multiple pages.

4. Your copied sources should be in the order that the items they refer to occur in your paper. If you have the same source for different items, you must have different copies.

5. Your paper must be in general manuscript form – typed, double spaced, last name and page number on each page, etc. Each section of your paper should start on a new page. And you must have a title page! Google it!

6. The first time (or even every time is okay) you mention one of the main 23 items in your paper, highlight it so it will be easy to see. If you use the item again later in your journal for a different reason, highlight it again.

7. If your Internet article doesn’t have an author, use the title of a website article if it has one or the name of the organization that produced the website if it doesn’t, and the year published or copyrighted. Do this for both your internal documentation & your Works Cited if your source is from the Internet. One difference between them, never use the URL in the internal documentation, but always include the URL in the Works Cited – and you can use just the first part of the URL since the whole thing may be really long.

8. Speaking of that, what you have listed in your internal documentation should match the first thing you have written in each entry of your Works Cited. For example, the author, the name of the book, the Internet title, dictionary entry, etc. Never, never, never include JUST the URL for Internet sites in your Works Cited. You must include the other important information as well. Follow the MLA guidelines Purdue Owl if you have any questions. And don’t forget to reverse indent your Works Cited!

9. Make sure you write the internal documentation for your illustrations BOTH on your illustration and also in your paper. And don’t forget to include it in the Works Cited!

10. Your Works Cited entries should also be in the order that they occur in your paper.

11. Double check to make sure you don’t have anything in the internal documentation that isn’t in your Works Cited, and vice versa.

May God bless you as you work!! I love you and I’m praying for you!!!

Chemistry 4-25-19 Chapter 6 Test Practice & Help Session

CHEMISTRY: Are you ready for the test tomorrow?!? Click below for the test practice from today. Below that is the short recording from the help session this morning.

If you haven’t already, first start by getting organized. If you haven’t made one already, make a chart, a really big chart of “What I need to memorize,” “What I need to know how to do,” and “What I need to be able to apply/discuss.” Then practice the things you have have the list!! Practice is especially important on the “problem” like objectives such as Lewis structures, drawing ionic bonding, etc. I would also encourage you to make lists of possible discussion questions and then practice answering them for the test. If there are things you are unsure about, go back and watch parts of old vodcasts.

A great way to help you study is to use the online textbook for this chapter. It provides an oral and visual review back through the chapter and also has practice quizzes, etc. It is great!

God bless you as you study! I’ll be praying for you!!

Thursday morning help session:

Chemistry 4-10-19 Polyatomic Ions & Molecular Geometry

CHEMISTRY: Great job with polyatomic ions and molecular geometry today! Who knew we’d be doing geometry in chemistry?!?

For tomorrow, be sure and print and read the cLAB: 3D Molecules! Advice for Lewis structures – don’t forget to count the electrons! And then double check the number of electrons. And when you think it’s right, count the electrons!! πŸ™‚

Advice for molecular geometry? Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Easy-peazy!

Lost Inside the Mponeng

Welcome to a great adventure! You’ve learned so much this year – not just concepts, but skills, and I can’t wait to see how you are going to apply it all!

Here’s the place where you can post your questions about the Lost Inside the Mponeng project so that everyone can see the answers.

First answer – the due date is Tuesday, April 30.

A really useful hint? Go back and re-read the project again – this time with a highlighter. It’s amazing how much I miss the first time I read something. So what’s your next question? πŸ™‚

Chemistry 4-9-19 Resonance

CHEMISTRY: Wow! Lewis structures, multiple bonds, and now resonance!

HW UPDATE: Homework that was scheduled for tonight has been moved to Thursday – due Friday. Thursday night’s scheduled homework is moved to Friday – due Monday.

Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!
