Welcome To Chem 7 June 16, 2014

Hi and welcome everyone!

1. Please download, read and understand the Chem 7 syllabus from the “Syllabus” tab of this website.

2. Please purchase the “Principles of Chemistry” 3rd Edition textbook by Martin Silberberg (the 2nd edition will also work, although there are some page number changes). Also please bring a non-programmable calculator to every class. Learn how to use your calculator if you do not know already 🙂

3. For the next class read Chapter 1 from our text and complete the assigned homework problems shown in the “Problem Sets” tab of this website. Most of this material should be a review of high-school chemistry concepts.

Chapter 1: 1, 3, 4, 5, 7, 8, 21, 23, 27, 29, 33, 35, 41, 46, 52, 56-58, 63, 66, 71

4. Jot down questions you have in the reading and ask these questions in class, or see me in my office and ask. Please don’t hesitate to leave a comment, quark, or question in the blog.

5. Our group needs to generate two potential recitation meeting times by next class meeting. The recitation is where you will go over homework problems. Please note the University precludes recitation classes on “activity days” which are Mondays and Fridays from 4:30 to 6:00PM.

PLEASE DON’T FALL BEHIND – this always leads to panic and problems at the semester’s end! STOP BY MY OFFICE ANYTIME!

Updated Equation Sheet March 16, 2014

Hi Everyone,

I updated the equation sheet to include Chapters 1-11. Hope it helps!

Updated Equation Sheet

RBG

Equation Sheet March 15, 2014

Here is an equation sheet that I normally pass to Chem 11 students. Omit the material we didn’t cover and hopefully you’ll find it useful too.

Please note, it does not contain “need to know” material from earlier Chapters:

Chapter 5 (PV = nRT, Molar Mass = mRT/PV, Dalton’s Law)
Chapter 6 (Internal Energy (E = q + w), Enthalpy (H = E + PDV), work (w = -PDV).
Chapter 7 Plank’s equation (E = hv, c = lambda v, DeBroglie’s Equation, lambda = h/mv))

Rick’s Equation Sheet

Lastly, so you know: a solubility table and activity series like those used in our textbook will be provided (as they were in Exam 1).

Quiz Tomorrow March 5 In-Class March 4, 2014

My apologies to the Chem 7 gang.

The planned quiz on Chapter 13 will be tomorrow morning at the end of the class period as discussed on Monday.

I wrongly assumed the morning class was canceled for Ash Wednesday mass when it is not. The 7:30AM classes are on, but the 9:30 classes have been canceled. My bad and my apologies if my post made for some anxiety.

Thank you Juzzy for pointing out my mistake!

Please let your classmates know (spread the word)!

See ya tomorrow!
