<p>@Hawkace I think it’s because COOH is a carboxyl. Carboxyls are usually like that</p>
<p>I’m self-studying Psych and taking it tomorrow. I’m also self-studying Stats and taking it on Friday. I taking Chem and USH during the year and taking on Monday and next Wednesday respectively. </p>
<p>@KbbGrizzly Carboxyls are just like that? Does that mean that I have to review organic chem again? Ugh. </p>
<p>Wait…I thought O-chem wasn’t on this exam.</p>
<p>organic chem is only like 1 q on the mc…dont worry about it</p>
<p>@Hawkace lol its cause Carboxyl groups/Carboxylic acids are just always separately arranged. I don’t think organic chem is gonna be significant in this years exam tho
look at this

<p>@HawkAce same here! Psych is way more down my alley but I didn’t self study–I independent study through an online charter school though. My school’s Chemistry and Biology classes were way different from the AP’s I was pretty much stumbling around but it might have something to do with the fact that I took Bio and Chem back in 9th-10th so I may have forgotten everything…eh. Psych is really just about the terms no math or anything so as long as you have a good grasp on the subject itself you should be good :). Have you taken a practice exam yet? I took one a couple weeks ago with my class and I scored pretty well–it was provided by my teacher so I’m guessing it’s an official CollegeBoard one. I will warn you though that there are a lot of self-studying Psych students who get 1’s so study hard!</p>
<p>@xxx123456xxx Well, I didn’t take a full practice test, but I went through the MC, and I got a lot of questions right. Do you know if the FRQ’s are difficult or easy?</p>
<p>@KbbGrizzly do you know what subjects are going to be significant in this year’s exam? Like nuclear and etc? Because I want to know what to isolate–there are literally 70 videos and in total like 8 hours long. I don’t want to study something that might not even be significant on the test. I also noticed that the number of MCQ’s dropped from 75-60? According to my Princeton Review 2013.</p>
<p>@HawkAce yeah the MC is pretty easy. The FRQ, they aren’t hard per se. There are 2 FRQ essays on the test and you need to give a full detailed essay. It can be 3-5 paragraphs long, I think. You will be given a general topic, for example, conditioning and then they will ask you how to use the different methods of conditioning(i.e. : fixed ratio, modeling, shaping and etc.) Every topic/term has to have a different paragraph and you have to define every Psychology term or else you lose points. Also you should write at least 1 sentence in the introduction.</p>
<p>@xxx123456xxx mhm. mc dropped questions. The overall concept of this year’s revised test is that it’ll be more based on conceptual and analytic thinking. The most important concepts I would say are as always titrations (equilibrium…acid bases),
Gibbs free energy concepts, Thermodynamics, and they added emphasis on spectometry this year. For the frqs I would recommend knowing how La Chatelier’s principle works, common ion effects, VSEPR theory and being able to explain how things work rather than memorizing a bunch of things. There’s gonna be less math than last years exam.</p>
<p>Can someone explain 39 on the practice mc?</p>
<p>@10bio10 HCL and CH3NH2 have similar molar masses. The more similar the masses, the speed will be similar as well. So since those two have similar speeds at which they diffuse into the each other, they’ll meet up in the middle to create a solid. If one was heavier than the other, then the solid would be created way at the left or way at the right.</p>
<p>Thank You that makes sense @KbbGrizzly.</p>
<p>does anyone have the lab page? pm if you do please :D</p>
<p>For the FRQ’s, the reactions frq (like they say X is titrated with Y, write solution) is gone right? </p>
<p>Which type of labs other than titration, grav analysis, spect, can really be tested on FRQs? + which can have them ask us for procedure?</p>
<p>also: can anyone give a more in depth explanation for 54? I got it right, it just took a longer time than usual. MgO had a much higher BP due to the +2 and -2 charges of the separate elements, and both NaF and NaCL have +1 and +2</p>
<p>@jiggla As far as I know that FRQ is gone but now they are incorporating equations into other questions.</p>
<p>For #54, the force of attraction using coulombs law depends on the distance, and since Cl is larger than F, the distance is greater making the force of attraction smaller. Smaller force = lower b.p</p>
<p>could somone explain #60 on the practice test</p>
<p>For the first FRQ, is the Ba2+ + S04 2- yields BaSO4(s) the precipitation reaction or neutralization? A solid form so i thought it was precip. but apparently it isn’t?</p>
