Re: Quadratic Formula [ENDORSED]
If you get two positive x values, plug both of them into the Equilibrium row of the ICE box (example: initial concentration - x). One of the x values is going to make the Equilibrium concentration value negative, which is impossible. Let's say you have x = 0.9 and 1.1 Initial Change Equilibrium : 1 ...

Re: Quiz #3 [ENDORSED]
From what I have heard, not everything from the Quiz 3 prep quizzes will be on the test. Some problems require ICE box and that is not in the first four pages of the course reader. Only material up to page 135 in the course reader is fair game.

Re: Fall 2016 #6C [ENDORSED]
^ Great explanation! Another reason you could be getting a larger number is because of the way you input numbers in your calculator. The first time I did this problem I got a larger number as well, but I went back and realized I had inputed a parentheses wrong. Be careful and always double check!

Re: HOMO to LUMO Concept
To add to what Rachel said, when light reaches a certain frequency and excites the electron (in the HOMO) then it jumps to the LUMO. We use HOMO/LUMO to measure energy differences between them + it helps predict the strength of the bond between the molecules.

Anti-bonds in MO Diagram
Can someone further explain what anti- bonds , signified by "*" on the MO Diagram, means? I remember that it is related to the location of the electrons in between the nucleus, but I am not entirely sure of its significance. Thank you!

Re: Video: How to calculate Equilibrium Concentration
I reposted onto Chemistry Community and shrunk the file. Is it viewable now? Thank you.

Re: Finding Chemical Equilibrium Concentrations
I had originally submitted this on Sunday afternoon, but didn't receive feedback until Monday-- my file was too large. Here is a repost. Hope this is better.

Finding Chemical Equilibrium Concentrations
Repost: Here is a video explaining one of Dr. Lavelle's post-assesment questions found on the Chem 14A website. I hope it's helpful!

Video: How to calculate Equilibrium Concentration
Here is the URL for a video I made that goes over one of the problems from Dr. Lavelle's post-assesment tests on Chemical Equilbrium (found on his Chem 14A website). I hope you find this helpful! https://drive.google.com/file/d/0B4n9cpLNxpKaNG9HOFFmWTljVU0/view?usp=sharing"onclick="window.open(this....
