12/21 Chemistry Class

Hi folks,

Well today we introduced the concept of the mole.  We will be doing a LOT more with this as we move on.  We also did a small lab where we found the amounts of different substances using the concept of the mole.

For homework….there is none!  Hooray!  However, I am included a folder that has all of the quizzes we've done so far this year.  I HIGHLY recommend going over each quiz and retaking anything you may be shaky on and, to be honest, I'd would recommend just doing them all from scratch.  Check your answers with your old quizzes.  From here on out, we will be using everything we've done before as a base so if you're iffy on any of these concepts the next part of the year will be tricky.  Take the time to really master this material.  If you do, the rest of the year will be much easier and your grades will be much better.

Have a great set of holidays everyone!!!

https://youtu.be/vrImUXZ4sMk




12/14 Chemistry Update and homework due 12/21



Hi folks,

First we spent a bit of time reviewing naming and balancing equations.  After that, we learned how to find the molar mass of molecules and we learned 5 different reaction classifications.

For homework this week, do the enclosed .pdf AND answer the following questions.  Answers at the bottom.

Find the molar of the following molecules.

1.  NaBr

2.  C5H9O

3.  Al(OH)3

4.  Fe(C5H5)2

5. How many atoms are in  Fe(C5H5)2

12/7 Chemistry Class update and homework due 12/14

Hi folks,

Today we spent a bit of time reviewing naming molecules.
We also began the next part of our "language of Chemistry" block and that is to learn how to read and write sentences. In other words, to learn how to read, write and balance chemical equations.

All of this is foundation for everything else that is going to follow so please take the time to really feel good about all of the material we've been covering in the past few weeks.

Homework for this week is to do the enclosed .pdf. The answers are enclosed so that you can really quiz yourself and get this material down pat.

Also, you may want to take a look at this website. It's the same one you used for the atom game a while back. It takes a bit to get the hang of what you are supposed to do but it may help to make things clearer.

Fwd: 11/15 Chemistry Update and homework due 11/22


Hi folks,

Today, we worked on the next part of the chemistry language and that is to be able to read and write the names of molecules.  We learned to name ionic and covalent molecules as well as polyatomic ions.

Homework for this week is to fill out the enclosed .pdf's.  I've also included the answer sheet so that you can check your answers.
