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!!
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!
WEDNESDAY HOMEWORK really is the work on the syllabus. It’s the limiting reactant problems from yesterday – go back and check your notes and/or watch the vodcast if you are having trouble! Help session?
HON CHEMISTRY: Missed you today! Here’s your first lecture on reaction stoichiometry. Were you able to apply what you remembered about moles from earlier this year? Don’t forget the keys! Now all you need is some practice and you’ll have it down pat!!
HON CHEMISTRY: Wow! Great job today! Here’s your first lecture on reaction stoichiometry. Were you able to apply what you remembered about moles from earlier this year? Don’t forget the keys! Now all you need is some practice and you’ll have it down pat!!
Let me give you some hints about making out your own study suggestion sheet for the test. First start by getting organized. If you didn’t do it in class on Friday, 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 start practicing 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 “Visual Concepts” part of 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! You can access this site by clicking here on the Chemistry Online Textbook or over on the right side of this page, or through Edline. The user name is csbec and the password is chemistry. (Both of these show up when you move the mouse over the online textbook link on Edline.)
And don’t forget that a great place to prctice dot notation and Lewis structures is at sciencegeek.net and practice the things from our chapter that are in the Unit 3 Review Activities. You get feedback right away to know if your answer is right or not, and that’s a good thing.
We’ve covered quite a lot in this chapter. God bless you as you study! I’ll be praying for you!!
PHYSICS: How much fun!! How’d you like playing with color? So now, why is an apple red? So….here’s the lecture on color – colors of light, and colors of pigment.
Rube Goldberg project ready for tomorrow? Make sure that you have a checklist for all the kinks!
CHEMISTRY: Molten iron, wow! Here’s the lecture from Wednesday on metallic bonding. Aren’t you glad there are no structures to draw?! Make sure you can use the electron sea model to explain the properties of metals. Also be able to compare and contrast all three types of 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 ionic vs. covalent 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!
How’s it going with the Lost on Hunga Tonga-Hunga Ha’apai 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!!
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.
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!!!
PHYSICS: Wow – how time flies when you’re having fun. Here’s almost the whole lesson on curve mirrors – all in one day! Well, it’s an introduction to curved mirrors anyway!
