Drawing arrows for nucleophile/electrophile

p.151 of the Organic Chemistry textbook shows the reaction of H3CH2COH2 --> H3CH2COH + H+ my question is, why is it a double arrow? the H shared 1 electron and the C shared 1 electron, so technically, didnt the C already have an electron and it should be a half-headed arrow? clarification would be a...

Re: Quiz 2 Winter 2017

9 yes 11 no could you please explain #9? It has to do with enzymes and I don't really know anything about them. It is not possible to explain everything about enzymes, but I will try to explain why the answer is D. First of all, enzymes are catalysts, meaning they increase the reaction rates of che...

Problem 8

the answer you gave has 3 sig figs but when I look at the values given there is a 0.35 M... to my understanding, any 0 before a decimal does not count as a sig fig. Therefore, the answer should be 6.6 min not 6.06 min

please advise

Re: 14.9 and using G=-nFE

Online research also clarifies that the number on the formula sheet is wrong.

Dr. Lavelle... this might be something you bring up to the people at the Course Reader store

3.21 d and d^10 orbital rule [ENDORSED]

Give the ground state electron configuration: d)Ag+ if Ag is [Kr]4d^9 5s^2, then Ag+ is [Kr] 4d^9 5s^1 the solutions manual has the answer as [Kr] 4d^10 I understand the half full d^5 and full d^10 orbital rule, but to my understanding it is only for Cr and Cu... my TA did this example in discussion...
