Re: Le Chatelier's Principle

Increasing the amount of acetic acid will increase the raw amount of protons in solution (read: hydronium ions), but it will not increase the proportion that dissociate. In fact, it will decrease it as I add more and more acetic acid - the reaction environment becomes more acidic, making it harder, ...

Re: Calculating Total Electrons

14 valence electrons and 4 core electrons (2 on C, 2 on O), so 18 total. I am happy to check on what exactly the video says if you wouldn't mind telling me exactly which video we are talking about.

Re: Bio Qpack vol 2 #99

The answer is a little bit in the question: This would prevent the plant in question from assembling spindle tubules, a necessity for the separation of sister chromatids in mitosis

Re: Question about NSTP FL Exams

In the most transparent words: In general I would recommend sourcing from 3-5 first - and if you feel like it, give a C&P section from 7-10 a shot at some point. That is probably the best way to get passage practice. As for recommendations in general: If there are topics you are weak on, definitely ...

Re: MCAT Physics Chapter 2 Practice Passage

The counterclockwise torque has to be equal in magnitude to the clockwise torque. This is a condition necessary for rotational equilibrium. Rather than solving and arriving that exactly the conclusion this problem arrives at, let me outline the steps to solving this problem and then discuss a small ...

Re: Diffraction & Slit Experiments

Ask yourself: What would I expect to have happen by shining a light through a hole? Whatever that is, an elaborate banding pattern is probably not anywhere near the top of your choices. However, for a sufficiently small hole, monochromatic light (of a single wavelength) and the right kind of separat...

Re: NS FL 4 C/P 37

That is the solubility, expressed in grams per 1000 mL. Like all solubility, it does not refer to any physical quantity - it is just a property of the substance. On closer examination, feel free to ignore this question for now. The use of solubility constants is definitely MCAT relevant, and the est...

Re: Work and energy quiz

I'm going to guess it is the trigonometry that is tripping you up. A 30/60/90 right triangle, such as the cross-section of a wedge-shaped ramp, has sides 1/root3/2. If the ramp is 10 meters long, therefore the height is half that: 5 meters. (Or in mathematical notation (sin30)*10=5) So we arrive at ...

Re: Biochem Q Bank 7 # 3

Hey there! My apologies that this took a small eternity to get back to. I would frankly not over-emphasize the importance of this question right now. It is reasonably good, but I will have to put this up for discussion a bit as to how reasonable the insulin-inhibition perspective versus the empirica...
