Hon Chemistry 4-26-18 Chapter 9 Test Overview & Help Session

HON CHEMISTRY: From Friday, here is our overview of the test. Again I want to emphasize – the majority of the test is basic reaction stoichiomety, limiting reactants and percent yield. Be sure and give that the most of your study time!

Also, review writing and balancing chemical reactions. Most of the stoichiometry problems will require that you begin by doing just that! There will be just one extra jumbo large problem. πŸ™‚

Below the vodcast for today is the help session from Friday morning. God bless you as you study!!!

Help Session from Friday morning:

Chemistry 4-25-18 Describing Chemical Reactions

CHEMISTRY: So tell me again – how do you know if a chemical reaction has occurred? Here’s the lecture on the evidences of a chemical change and the intro to balancing chemical equations. Great to be back to chemistry!

Hon Chemistry 4-23-18 Percent Yield

HON CHEMISTRY: So are you a cookie dough lover? Not me – I like my cookies crispy!

Here’s the last of the applications of stoichiometry problems – percent yield. Lots easier that limiting reactants I think. You realize what we’ve done… we’ve finished the chapter!!

Not only that, did you get a heads up on designing the percent yield of magnesium oxide lab for Monday? πŸ˜‰

Lost in the Don Juan Basin – The Last Weekend!!!

It’s you last weekend to work, so how’s it going with the Lost in the Don Juan Basin 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 – 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 u 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 first page and the page that you use, and highlight the portions that you use. 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. Always 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 published or copyright date in 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!!!

Hon Chemistry 4-19-18 Limiting Reactants

HON CHEMISTRY: So if you have 11 roller wheels, how many roller blade skates can you make? You know, really, limiting reactant is almost that simple. Well, the concept is anyway! You deal with limiting reactants in your life all the time. Now we’re just applying that same concept with chemical reactions! πŸ™‚

  • Chemistry 4-16-18 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!
