Re: 2000Q Book: General Chemistry #1344

Thanks for the question! So this table is showing the standard reduction potentials (i.e. how badly does each compound want to be reduced). Whichever compound has the highest reduction potential will also, by definition, be the best oxidizing agent, since a compound being reduced means it is oxidizi...

Re: Study plan

Thanks for the question! There are different approaches, to be sure, so you'll want to try to figure out what will work best for you and then make any necessary adjustments as you go. Typically, a recommended timetable for dedicated review is somewhere on the order of 3-4 months. With that timeline,...

Re: TLC/HPLC/RP-HPLC Question

Thanks for the question! Essentially, the mobile phase is what moves down through the column and the stationary phase is what's not moving (instead, it's sort of bound to the column). You can use these techniques to separate compounds based on each compound's affinity for a given phase. If a compoun...

Re: Typo? - Psyc/Socio (page 29) - MCAT BOOKS 2018 edition

Yep, definitely a typo. It should read "cell" instead of "call." I'll let the content team know and we'll make the change for the next edition of the books.

Thanks and good luck with your prep!

Re: FL 3 C/P Q52

Thanks for the question! We can basically do this because of the options that are present in the answer choices. If there were values like 9 J, 10 J, and 11 J, then we'd need to know exactly how much energy would be lost due to the imperfect elastic springs of the rabbit's legs. Since the answers ar...

Re: Chem review

Thanks for the question!

Positive values are used for temperature here because the formula in question requires us to use ∆T instead of a value for T. In first part of the example, the water is increasing from -20°C to 0°C which is a ∆T of +20°C.

I hope this helps clarify it and good luck!

Re: Chemistry concept Q

Increasing entropy means more disorder and would correspond with a positive ∆S value. If something becomes more ordered, then entropy would decrease and ∆S would be negative. Note, however, that we have to be finicky about what we're talking about when we say entropy is increasing. With a protein, f...

Re: NS FL2 B/B Q56

Thanks for the question! I think this is really a matter of degree. If we lyse the molecule, then it will certainly not work as intended. If we change out certain parts of the molecule then, yes, it of course might alter the function of that molecule, but is also might not! Likewise, if we remove al...
