I am still confused, because if you identify the double bond as the 1st carbon and move right, you're still moving across the double bond, and the sum of 2,3,4,4 would be less than 1,5,5,6. I was under the impression that the priority was about the sum of numbers identified, not the 1st of the numbe...

Also, the 0.05916V value is (RT/F)*ln(10) to convert the form into log instead of ln.

I believe the difference is that in ether oxygen is bonded to 2 hydrocarbon chains, while ketone has 2 hydrocarbon chains to a single carbon and also connected to that carbon is a double bond to oxygen

Bruincast on Wednesday 2/22 is not working. It only goes until 8:30 and stops there. I emailed bruincast and just wanted to post if anyone was wondering the same. And if you see this I also hope you email them too: bruincasthelp@ucla.edu ALSO any advice for how to make bruincast work on a windows co...

Is the green course reader the same thing as what is being referred to as the ochem textbook?

So should we be taking the green course reader to class tomorrow or the blue one we have been using?
What does Prof. Lavelle mean the green course reader when he mentioned "Organic Chemistry textbook (black & white printing)" in his email earlier today?

Can someone explain why question 10 is false? I thought half-lives are always the same. I think half-lives are the same for only 1st order reactions To expand on this, if you look at the half reactions formulas, you will see how both the 0th order rxn and the 2nd order rxn are dependent on the init...

Will we be given a table of or a list standard cell potential values? While taking the 2013 winter midterm, when I got to question 8A, I wasn't sure how to get the Enot values

It also helps that when you're looking at the E_cell equation, the course reader says E^o_cell=E^o(cathode)-E^o(anode), but it's easier to understand it as E^o_cell=E^o(cathode)-E^o(anode). This way you're not confusing when things are supposed to be negative and positive.

Can you/someone elaborate and explain the relation of the reaction being intensive applies to the number of moles reacting?

#11 approach First you want to find the amount of heat released by the PbO reaction -you do that by converting PbO grams -> mols -set up ration of (-106.9kJ/1mol)=(q_p kJ/n mols of PbO) With q_p that you just found, that is the amount of heat you have to heat m grams of H2O from 25C -> 100C -find ma...

q=nC[delta]T
where C_v,m=(3/2)R and C_p,m=(5/2)R

Check out page 281 in the textbook! Note the whole part about monatomic gases

How many unit places do we need with each of the conversions? Like before we get the cheat sheet and all?
