Chemistry 2-24-21 Making Gases Pre-Lab

CHEMISTRY: Here’s our very short look at the positive tests for carbon dioxide, oxygen, and hydrogen gases for the experiment: Making and Testing for Gases. If you were absent on Wednesday, be sure and watch this vodcast – it’s required before you can do the lab. Make sure you have shown me the three balanced equations you’ll need for the experiment. I think you’ll have lots of fun with this one. πŸ™‚

Chemistry Thursday & Friday Remote Learning Assignment

CHEMISTRY: Are you surviving the snow? Thursday and Friday you’ll be working on practicing memorizing and using the 17 types of chemical reactions.

Thursday: Do the ODD questions on Balancing Equations Worksheet 3. You can either answer on the worksheet, or you can answer on notebook paper. If you answer on notebook paper, skip a line between each equation. To turn it in, make a CLEAN scan of your work and submit as a PDF to your Chemistry shared folder in Google Drive. Include WS 3 Odd in the save as title.

Friday: Do the EVEN questions on Balancing Equations Worksheet 3. You can either answer on the worksheet, or you can answer on notebook paper. If you answer on notebook paper, skip a line between each equation. To turn it in, make a CLEAN scan of your work and submit as a PDF to your Chemistry shared folder in Google Drive. Include WS 3 Even in the save as title.

I miss you! Hope you’re staying safe and warm – and having a lot of fun in the snow, too!

Chemistry 2-17-21 Activity Series & Completing Chemical Equations Review

CHEMISTRY: Happy snow week! Here’s the lesson for Wednesday. It’s the LAST of the notes from chapter 8. At the end is a great review of completing and balancing equations. Also be sure and check the syllabus to find out about the optional homework assignment that will be great help if you’re having trouble predicting products of reactions.

So guess what happens when a gummy bear falls into a test tube of molten potassium chlorate?! Click on the video below to find out! Do you reckon that it’s a physical change or a chemical change? Why do you think?

Remember these steps when you are completing chemical equations: #1 – write the correct formulas; #2 – ask yourself what type of rxn it is; #3 – find the rule that applies and go for it! Don’t forget also that if you answer single replacement to #2 (or the synthesis or decomposition of a metal oxide!) you’d better check the activity series first!! Good luck!

Chemistry 2-12-21 Double Replacement & Combustion Reactions

CHEMISTRY: You realize what we did? We finished all 17 types of reactions today! Have you been practicing using them?

HOMEWORK UPDATE: Your homework for the weekend is the Physics Classroom activity that’s listed on the syllabus. It is due Tuesday morning, 8:00 A.M.

Are you working on memorizing all 17 types of reactions?! But don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!! (and yes, I realize I am repeating myself, but I do and you can!)

Chemistry 2-10-21 Single Replacement Reactions & the Activity Series, Pt. 2

CHEMISTRY: Good job today on single replacement reactions! And great job using the activity series!

We’ve done 15 so far – how are you doing on memorizing them?! Careful though, don’t just memorize. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!!

Chemistry 2-9-21 Activity Series & Single Replacement, Pt. 1

CHEMISTRY: What!?! You mean there aren’t little green people on lonely country roads? πŸ˜‰

Great job applying the activity series to synthesis and decomposition reactions. As you practice, go back and check the activity series and your notes on the activity series!

Chemistry 2-8-21 Decomposition Reactions

CHEMISTRY: Great job with synthesis and decomposition reactions! Now can you use them? And how are you doing on memorizing them? Best way to learn them – practice!! Below are the lessons from Friday and today on synthesis and decomposition reactions.

HOMEWORK UPDATE: The page numbers for the homework are wrong. Always book homework will be the chapter review at the end of the chapter that we’re currently working on. We are on chapter 8, and I believe the homework starts on page 284. I think. Maybe. Check it out.

Chemistry 1-28-21 Thursday’s Assignment

CHEMISTRY: Today in class you’ll be practicing writing balanced chemical equations from word equations. If you are Zooming, the worksheet you need is here:
Balancing Equations WS 1a

Work neatly! If you need to, do your scratch work on notebook paper and then transfer your balanced equation to the worksheet. If you can’t print the worksheet, you can write the balanced equations on notebook paper. Skip lines between the equations.The worksheet is due Monday.

Final hint – be sure and check the chemical formulas before you balance the equations!!
