Re: Saying Thank You to Dr. Lavelle
Dear Dr. Lavelle, I really want to thank you for all the work you have put into the class. I want to thank you for the way you present each lecture, the way you have set up chemistry community so students can get help 24/7, and the way you show off a genuine passion for chemistry and how you inspire...

Re: Intermediates in pre equilibrium
Ohhh, so the review session will also go over post-midterm materials? That's also good to hear. I had a few questions regarding chemical kinetics after Quiz 2.

Re: Midterm Winter 2017
A quick question: Are we allowed to ask questions about midterm problems on Chemistry Community now or do we have to wait until we get our exams back?

I'm a fan of Futurama, especially of their science jokes! This one isn't as complex as their other jokes as its a simple wordplay but I still thought it was funny.

Question regarding: "E° + Value means reduction is spontaneous"
Hello, just a quick question on what "E° + Value means reduction is spontaneous" means. It's on page 46 of the course reader.
What do they mean by "value" and is there a case when E° is not spontaneous?

Re: Video Competition
So where exactly should we post the video? Do we post in the respective subsections of the equations? (For example, a video on thermochemistry equation posted as a topic on the "Thermochemistry" section)

When to convert into Kelvins by adding 273.15?
So I am kinda confused on when I need to convert Celsius into Kelvin by adding 273.15. For example, on Q2 of Midterm, I converted the temperatures listed into Kelvin by adding 273.15 but according to the answer key, the answers could be switched from Celsius to Kelvin without any adding (-70C = -70K...

Having trouble with bond enthalpies of Q1B on Midterm
For Question number 1B of the midterm, the answer key state that a C-C bond was broken but I cannot find that info on the figures. I can see C-O and C-H bonds breaking and O-H and C-C bonds forming but not C-C bond breaking. Can someone tell me how I can interpret that info based on the figure for t...
