Hey Kiddos- this is a friendly reminder that even with warmer weather, you still need to cover your legs and feet for chemistry class! No exceptions.  See you soon, jb 

Good morning students,
Here are two videos walking you through sample calculations on p.60 of the solutions manual for Lab 10.2. Be sure to have these as well as the paragraph completed by Thursday. 
Happy Monday!

Part One

Part Two
 

So, winter break is here!  Sadly, we did not get to complete our lab today, but we had some good teaching time to clear up any misunderstandings about titrations and such. 

You’ll notice on the homework that there is not a lab linked for Feb 11. We will perform the titration, which you’ve already written up.  Do not write up another prelab. 
Enjoy your time off, and I’ll return emails on Feb 8 when I’m back in town. jb

Hey Guys,

Hope you had a wonderful Christmas break! I am sure you all know this, but just in case, chemistry starts back this Thursday, Jan 7.  You have a week of homework due that day (it has been posted since we got out Dec 3).

We will also be having the Polyatomic Ion Quiz (see p.288) at the beginning of class.

For lab, bring a plastic comb for Lab 9.1 (don’t forget a prelab). If time, we will also begin the Molecular Geometry lab with models.

I’ll see you Thursday!

Hey Kiddos,

You did it! You are halfway…  Good work!

I hope your break is restful and fun. Remember that you have one week of homework due Jan 7, along with a quiz that day (p288 ions).

I should have exam grades posted by Monday. For those of you who need to complete the Naming Ionic Compounds Worksheet, it is now posted (for practice) on last week’s homework. I hope to go over it on Jan 7.

Have a Merry Christmas! jb

Students,

In case you have forgotten… we will be having our Semester Exam this Thursday in class.  🙂 Please be sure you have your calculator!!!

If there is time remaining after the exam, we will be building molecular models for our lab, utilizing Lewis dot structures.  You may bring a snack to share during this time (no nuts, please).

You are almost halfway done with the class! You have worked hard; let’s finish strong on the exam Thursday.

See you soon!

Students,

As you are working on dot structures this week… these videos might help. You may notice a few concepts that your book doesn’t address (e.g. resonance, formal charge), but in general, these will be very helpful for Modules 8 and 9.

See you Thursday! jb

Hey Gang,

Good news! Your old tests are now linked to the Homework page of the website (second bullet).

Remember that we have one more regular class next week and then the exam is Dec. 3.  You may bring a snack to share Dec 3 after the exam (no nuts, please). We will finish our molecular geometry models during the rest of the class time after the exam.

See you next week! jb

If you are interested in extra credit tomorrow, bring graphs or an explanation of the graphs of direct and inverse relationships. (You would need to bring an explanation of the graphs or draw a graph of both types of relationships.) jb 

Hey Guys- two quick items…

1- thanks to Daylor for discovering the homework error.  It looks like I messed up Day One. You might want to start with Day Two today and work on Day One later. 

2- the unknowns were CaCl2 and BaCl2. Be sure to include whether you got these right or not in your Postlab. If you did not, include an explanation. 
Have a great weekend! JB

Geaux Tigers! 🐯💜💛💜
