Hon Chemistry 4-26-18 Chapter 9 Test Overview

HON CHEMISTRY: I still say stoichiometry is a lot like baking – sometimes you just have to get in there and get your hands dirty! Here is our overview of the test today. 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. You’ve got this!! 🙂

Chemistry 5-7-19 Describing Chemical Reactions

CHEMISTRY: So you learned last semester how to determine if a chemical reaction has taken place. How would you go about describing a chemical reaction to someone? Here’s our discussion from today on writing balanced chemical equations!

Chemical formula memorization quiz tomorrow! First step in writing equations? Make sure you can write chemical formulas! First step to that? Memorization!! The quiz tomorrow will have writing and naming monatomic ions, polyatomic ions, and acids. It will be short – 18 questions in all.

So tell me again – how do you know if a chemical reaction has occurred?

Lost… Project Web Post Comment

I’m excited to read your projects and find out what you did to survive!! Did you do more than just survive the project? Here’s where you post you comment for the week.

Web post topic – What did you learn from the Lost… Project (not related to chemistry). What did God teach you through the project?

Go!

Hon Chemistry 5-3-19 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! 🙂

  • Chemistry 5-3-19 Ionic Bonding Review & Test Notes

    CHEMISTRY: Soooo many dots!!! From Friday, here’s our very short overview of the ionic bonding equations that will be on the test. How do you feel about the Chapter 6, Part 2 test on Monday? Need practice or help? Help session Monday morning, 7:20ish.

    The Chapter 6, Part 2, test will be a shorter test and will be over:
    1) All of ionic bonding (even the info from the beginning of the chapter)
    2) Properties of ionic and covalent compounds and how they compare
    3) Metallic bonding

    Study hard and PRACTICE!!! I’ll be praying for you!!

    Hon Chemistry 5-2-19 Stoichiometry

    HON CHEMISTRY: Here’s our discussion of reaction stoichiometry – all in one place. 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!!

    Chemistry 5-2-19 Ionic Vs. Covalent Bonds & Metallic Bonds

    CHEMISTRY: Happy Monday! Here’s the lecture on ionic vs. covalent bonding, followed by metallic bonding.

    Aren’t you glad there are no structures to draw for metallic bonds?! 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 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!!!
