Re: Former, latter, and respectively

Hi JBike, "Former" and "latter" form a pair, so let's tackle those first. If you mention two things in a row, "former" refers to the first thing and "latter" refers to the last thing. For example, if I say "The two factors of X and Y contribute to childho...

Re: Chemistry and Organic Chemistry Book: Rydberg Formula

Hi Xuyuanify, You're absolutely right, and we will fix that error in the next edition. The silver lining, though, is that for the MCAT, you can probably make a mistake like that without it mattering! The reason for that is because the absolute magnitude is the same either way -- that is, the same am...

Re: Study Plan CARS Error

Hi jpetrera, I believe we've replied to you through email as well, but just wanted to post this response in case anyone else has the same question. Like all other light-colored assignments, the "complete 2 passages" assignments are optional, so we've added them to the plan and you can comp...

Re: PSYCH FL 10

Hi lmnajarian, Thanks for the excellent question! You're right that these two factors seem similar, and in general, that's always a tricky aspect of groupthink, because the various factors work together to create the same outcome. The most important difference is that the administrator describes in ...

Re: NS is WRONG!!on CHEMISTRY QBANK 4 # 12

Hi PoincareConjecture,

You are correct -- but there's another error yet, because 20 x 10^-6 = 2 x 10^-5, not 2 x 10^-7. We'll fix this ASAP. Thanks for pointing this out!

Re: Chemistry and Organic Chemistry Page 6 Question

Hi jpetrera, Thanks for the question! You are seeing that correctly and we will make a note to fix it in the next edition. However, an interesting fact is that for the purposes of the MCAT, you can often set up the Rydberg equation in whichever way will make the math easier for you to do, because th...

Re: QBANK Biochem Proteins & Enzymes #11

Hi PoincareConjecture, Yes, this is a tricky question that draws on a less commonly known aspect of how enzymes work, although when you think about it, it's logical that they will have a very high affinity for the transition state. (The Wikipedia article on transition-state analogs is interesting re...

Re: Physics CR Chapter #6 Air resistance equation

Hi ashleyeyoung5, You are correct that there is generally a (1/2) term in the equation. It looks like what's happening here is that the coefficient value they give as 0.2 already takes that into account, because the drag coefficient of spherical objects in air is generally more like 0.4-0.5, so the ...

Re: Physics Ch4 Independent Question 5

Hi vgp1993, Excellent question! If I understand your reasoning correctly, that would result in an answer of 70 J, not 0 J, though, because you would still have to account for the 70 J of energy that the question describes as coming from out of the system. From the point of view of pure question-solv...

Re: Lesson 6 video 4

Hi Ariel, Before getting into a more detailed response, I think it might be useful to step back and make sure that the terminology is clear. I wasn't quite sure what you meant by "rotating" in the S configuration. Although we might mentally do some rotation to help us visualize the molecul...
