Extra Credit for Chemistry
Hi folks,
A small extra credit opportunity here for you. 5 points if you can figure out what the common "I can get this at the store" items are for the chemical formulas in this grocery list. I must admit, I'm not sure what #5 is either so you can skip that if you want. Good Luck!
Change of classroom space
Hi folks,
I'm sorry for the confusion before. ALL classes will be held at this location from now on. Sorry that that wasn't clear.

New Location for Biology!!!
Hi folks,
Remember that location that fell through for us earlier in the year? Well it's available now and I'd like to start using it for classes this week.
The location is at 6901 Turkey Farm Road Chapel Hill, NC 27514. It's on the way to my house but you take a left on Turkey Farm road (assuming you're coming from 86) and it's about 500 ft on the left hand side.
I hope this doesn't cause any inconvenience. See you all soon!

4/26 chemistry update and homework due 5/3
Hi folks,
Last week we spent time getting deeper into moles and talking a look at stoichiometry. It's quite intimidating at first but hopefully it will be easier with practice.
Homework this week:
Do questions 5-8 on the enclosed .pdf. Check your answers carefully and really try to get comfortable with this.

Re: 4/19 Chemistry update and homework due 4/26
Hi folks,
Karan caught a typo. In the second question #5 on the "Complete and Balance" sheet BaCl should be BaCl2. Sorry folks and good job Karan!

Is number 5(second number 5) balanced? The answer shows 1 'Cl' on the left side and 2 'Cl' s on the right side.

Today we covered three topics. The 5 different types of chemical reactions, how to predict reactants from products and we began working with moles.
Homework for this week is to do the enclosed two question sheets. Both have answers so that you can check your stuff and really get the hang of this. Really try to get comfortable with the mole concept. We are going to be doing quite a bit with that in the next class or two and the more comfortable you are with it now, the easier it will be.

4/12 Chemistry update and Homework due 4/19
Hi folks,
Today we reviewed naming a bit more and started working with balancing chemical equations.
Homework for this week is to do the following .pdf. Answers are included (good ones this time :) ) so that you can check your answers.

Home work sheet
Hi folks,
I missed the fact that the sheet has a bunch of polyatomic ions that I didn't ask you guys to memorize. When you come to the problems with those, either (a) google them or (b) skip them.
Sorry about the frustration on that.

Don't worry about Phosphite. It's H3PO3 but I didn't ask you to know that one.Other problems that aren't in the answers:#15 Lead Phosphite?#16 What is Heptoxide?
Heptoxide is O7 Another strange question. Heptoxide doesn't stand on it's own it's always with something. Like, dichlorine heptoxide. Cl2O7

Problem with the homework's answer key
Hi folks,
It turns out that the answer key to this weeks homework is a little odd. Some of the answers have nothing to do with the problems. Here are some corrections that Gideon was asking about.
#5 FeSO4 would be Iron (II) Sulfate
#12 Cu2S would be Copper (I) Sulfide
#14 I2 would just be Iodide.
Let me know if you guys need help with any others. I'm running quite a bit tomorrow but I'll try to help.
