Chemistry 11-10-17 Oxidation Numbers

CHEMISTRY: One man’s rust is another student’s lesson in chemistry! Great job today with oxidation numbers. Now it’s time to go and practice applying them! Need help? Decide on a time for the help session and let me know! πŸ™‚

How did you do on the mock pre-test? Are you ready for the REAL pre-test TUESDAY? For the pre-test you need to have memorized (and be able to use!!): polyatomic ions, monatomic ions (but you can get these off the periodic table), acids, prefixes, the chemical names and formulas of common substances, and how to apply the oxidation rules to write and name chemical formulas.

That’s a lot, but you can do it! And make double dog sure you are working hard at memorizing it all now!!

Chemistry 11-7-17 Binary Molecular Formulas

CHEMISTRY: Do you feel like you have letter and numbers swimming in your eyes? This is one of those times that paying attention to details is super, super important! Here’s the lecture from today on writing formulas and names for binary molecular compounds. Part of it’s really similar to what you learned to do last week for ionic compounds, but another part is totally different. Details!!

Make sure you keep everything straight. Do something that will organize all the information for you, so you won’t get confused. Also, don’t forget the lists you have to memorize – it’s getting larger and larger!! And practice, practice, practice!!!

Need extra practice? Help session tomorrow morning, 7:20ish A.M.

Chemistry 11-3-17 Practicing Chemical Formulas

CHEMISTRY: Does writing and naming chemical formulas tie you in knots? I hope today’s practice helped!

The vodcast below is the work we did in class going over last night’s homework: #21, 23, 41, and 44.

Keep working on it – both practicing and memorizing polyatomic ions!!! The knots are all going to come unraveled and you are going to master this!!

Chemistry 11-2-17 Chemical Formulas with Polyatomic Ions

CHEMISTRY: Great job today! Do you understand better now? Remember it’s like baby steps, first binary ionic compounds, and now, formulas with polyatomic ions. Begin learning them now! And practice, practice, practice!!

Another great idea, click here for a copy of the Hints for Naming Chemical Formulas Flow Chart, or find it under the Worksheet/Handouts Tab. Follow it every time you name chemical formulas!!

Chemistry 11-1-17 Intro to Chemical Names & Formulas

CHEMISTRY: Great job learning to name binary ionic compounds – and even beginning to write formulas! Tomorrow let’s add polyatomic ions! Whoot, whoot!!

Speaking of formulas, what is your plan for all the memorization in this chapter? Word of warning – don’t wait to the last minute!!

Super important – the secret for the next few days and this entire chapter is DON’T GET BEHIND! Keep up with me and practice, practice, practice!

Chemistry 10-23-17 Chapter 1 Test Overview

CHEMISTRY – Are you ready? God bless you as you study! Here’s the overview of the test that we did in class today. Speaking of videos – have you watched the video clips on Cu, P, and Si? You can find them at www.periodicvideos.com.

Make sure you aren’t just reading your book and notes. First, memorize the facts, then go back and make sure you can apply the concepts. Study examples, make your own examples, practice making questions. And don’t forget, if you are getting lost with everything you need to know, or if you’re not sure how to study, Chapter 1 Stuff to Know Sheet under the Test Info tab

Also, don’t forget the great review games that are in the Student Premium section of the online textbook. You can do this – I believe in you! I’m praying for you!!

Chemistry 10-18-17 Conservation of Energy

CHEMISTRY – Happy Day!! We finished the chapter! Now it’s time to go apply what you’ve learned. Have you begun to think about ways you could separate that mixture? And what about a Plan B? πŸ˜‰

So can energy be destroyed? Good job on tracing the energy transformations from one form to another. Applications, applications! Make sure you can apply what you learned today – on the test (and in life!). Did I mention that already?

Hey, have you had a chance to check out the chapter 1 study suggestion sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?) πŸ™‚

Chemistry 10-17-17 Elements & Intro to the Periodic Table

CHEMISTRY – Happy Tuesday! Here’s our overview of the elements and intro to the periodic table. Did you feel like it was mostly review?

How is the element handbook search going? You will be responsible for the information from Handbook Search 1 on the test. Tell enough to show what distinguishes that element as the type that it is – physical and chemical properties, where it can be found, what it’s used for, anything particularly unusual about the element, but don’t go into minute detail – just the main facts. You for sure don’t have to copy information from all the tables in the book.

Here is the link for the video clips on copper, phosphorus, and silicon that you will need to watch for the Element Handbook Search and for the TEST!! www.periodicvideos.com. The information on these video clips will be on the test.

Speaking of the test, have you had a chance to check out the Chapter 1 Stuff to Know sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?)

Chemistry 10-16-17 Classification of Matter

CHEMISTRY: Here’s a mixture that looks like it might be worth investigating – bacon caramel popcorn! I mean, I like bacon and I like caramel popcorn, but bacon caramel popcorn? Hmmmm….

So now that you know about mixtures, could you figure out how to separate one? Keep these notes handy!

Chemistry 10-4-17 Properties & Changes

CHEMISTRY: So how do you know if something is a physical or a chemical change? Applications, applications! Make sure you can apply what you learned today. Ditto on the law of conservation of mass.

Don’t forget that we will do the thLab: Candle Observation in class tomorrow!
