Re: pH using Nernst Equation
We would know it's not E*cell because that would be the standard cell emf, i'm not sure about the n though, could someone help? I'm wondering about that too...

Re: chapter 3 question 9
There is steric strain because the two unbonded C molecule on top are too close together which causes its substituents (2 bulky molecules) to hit each other. There is torsional strain because since the molecule has Carbon single bonds, it can rotate and thus become in the eclipsed conformation and h...

Re: Neo- vs. Tert-
neo- and tert- are sometimes used in iupac naming just to make things easier, but using just iupac would be correct as well

when there's a chair flip the only thing that happens is that all the axials become equitorials and equitorials become axials

Re: Numbering counterclockwise or clockwise
I have a related question - what if there is a functional group as well as a double bond? I know that the carbon attached to the functional group would be the first one but if the double bond isn't attached to that same first carbon, which was does the numbering go? Or does it not matter? A double ...

Lavelle said that he would never explicitly ask for common names, he said he with either just ask for the name (in which case you have the option of IUPAC or common) or just eh IUPAC.

Sorry, if Lavelle already mentioned it, but what was the average for the midterm?
Thanks!

Re: Quiz 2 Winter 2017
As for number 7, when do we know to use the rearranged integrated rate law and when to use the differential rate law? I think the differential rate law talks about the overall rate while the Integrated Rate Law talks about rate as a function of time (usually a particular moment in time). So,when ti...

Re: HW 14.5
yes, so because it is not balanced, you would have to balance it first. It would be: H+ + O3 -> O2 + H2O, which is a reduction half reaction.

Re: 2013 Midterm 8B
you can simplify it first. When you simplify it you get 0.02958xlog [Fe]0.015^2/0.015^2=-0.15. So now you have to get log alone so you divide it over and get
log[Fe]0.015^2/0.015^2=-5.07, and then you just solve it normally!
Hope that helps.

I think increasing temperature increases entropy because heat excites the molecules and causes more random movements.

I've downloaded silverlight multiple times for chrome and it never works, so I think the best option is Safari.

Re: Hw problem 1.13
Also, you might have left your answer in meters which is why you have the negative exponent. Multiply your answer by 1.0x10^9, and that should get your answer to nanometers.
