Transition state over reactants.

Will we be given the strain/relative energies in order to calculate the ratio of the conformations? Because I don't think we ever explicitly went over how to find that...just how to find the ratio?

Will we have to know how to write the common names because I've gotten pretty used to the IUPAC and I don't want to get confused?

So does that mean that all of chapter 1 will be on the test then? I'm asking because attached shows what Lavelle's email said which sounds like all of chapter 1 will not be included. I'm simply asking if I should know how to do all problems listed for chapter 1 in the course reader (1-6, 9-17, and 2...

Where does quiz 3 cover up to in the homework questions? Someone said constitutional isomers are included which would basically mean all of chapter 1 but Dr. Lavelle said that it won't cover all of chapter 1.

I know that quiz 2 covers up to page 73 in the course reader, but where does it cover up to in the homework problems? Is it up to 15.55 because 61 starts talking about activation energy?

Friend: Hey, what show does cesium and iodine love watching together?

For the winter 2015 #8d I'm having trouble figuring out why the standard potential is 1.239? When I calculate it I get 0.124? I'm literally putting the same numbers as it says on the paper so how did 1.239 even come about?

I'm not sure if this has been answered before, but do we have class on the Wednesday of the midterm?

A photon checks into a hotel and is asked if he needs any help with his luggage. He says, "No, I'm traveling light."

Friend: Hey did you hear oxygen went on a date with potassium?

Me: Yeah I heard it went OK.

What is a cation afraid of?

A dogion!!

So from the example that Dr. Lavelle did yesterday when we were calculating x the equation was: 5.55x10^-10 =x^2/0.0600- x then we made it approximately equal to x^2/0.0600 which assumes that x was zero right? Can we expect to do this on the final instead of using the quadratic equation? Or should I...

Hi,
The value 1.0 x 10^-14 is just the Kw which is the autoprotolysis constant...it's in the course reader if you have one page 149!

Remember: 1.0 x 10^-14 = [H30+][OH-]

Does anyone know if everything in the quiz 3 preparation will be on the quiz? For example I know that MO diagrams will be on the quiz even though it's not in the preparation. It looks like some things we just went over today is on there?

Diana_Anum1G

Okay thank you and we have to memorize the ligands and their names too?

Diana_Anum1G

We have to memorize the correlation diagrams for Z < 8 and Z >/= 8 right? Or will it be given to us on the quiz and we just have to fill it in?

Diana_Anum1G

Hybridization of lone pair is the same as the hybridization of the atom it surrounds...not sure if it's on the test or not

Dr. Lavelle: Know any jokes about sodium?

Me: Na

I understand that we don't have to memorize the bond angles, but since we have to know the names of the molecular shapes should we also know the actual shapes too?

Diana_Anum1G

Yes total

I believe isoelectronic means having the same number of electrons or the same electronic structure. So for example K+ would be isoelectronic with Argon.

So for the questions in the workbook for quiz 2 preparation, it seems to have a lot of problems concerning hybridization and sigma and pi bonds and stuff like that. I am not familiar with these topics and I don't believe we've covered them in class so are these going to be on the quiz? I thought the...

Will there be a session tomorrow and can we work on the workbook questions for Quiz 2?

Diana_Anum1G

I was having some trouble understanding this on the homework too. If there is a charge will it usually be given in the question or is there a way to determine it?

Another question: When we calculate wavelength, will the answer be correct if I leave it at m or must I convert it to nm? I've only been converting if the question says to but I want to be sure

Diana_Anum1G

So just to be certain, the quiz is going to include all that we've learned in the lectures up until this Friday, the topics in the modules, homework, and the fundamentals right? Will the focus in the fundamentals be only on the ones assigned (E, F, G, H, L1-2, M) or will it generally include all the...

I live in Sproul Cove but I would like to join the group if it really is going to be a thing.
