Chemistry Thursday & Friday Remote Learning Assignment

Posted on by

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!

Hon Chemistry 2-18-21 Isotopes & Average Atomic Mass

Posted on by

HON CHEMISTRY: Here’s the lesson for Thursday! Isn’t God awesome to give us minds to understand the world around us – even the parts we can’t see!

Today we talk about isotopes and calculating average atomic mass. Make sure you practice all the ways to write nuclear symbols. Also make sure you can use them to determine the number of protons, neutrons, electrons, etc., AND be sure you can use the formula to find average atomic mass!

Here are some answers for tonight’s homework:

#19) 39.95 u
#20) 10.00 u
#34) 9 x 10^12 more dense

Can you believe atoms are that small – and the nucleus even waaaaaay smaller! The thumbnail is a picture of atoms from the IBM Almaden Research Center. These are iron atoms on top of copper. Being able to move atoms around like this was a giant leap in the field of nanotechnology! (Sorry about that, bad pun! 🙂 )
