Hello, since beginning undergrad I've been interested in MD/PhD, but due to the competitiveness of the MSTP programs I have always been concerned about the viability of these plans. Now that I'm applying in a month, I've done a lot of self reflection and I'm going to try to apply to some...

Hey SDN, I'm trying to just get some clarification on Melting point and Boiling Point properties between Ionic and Covalent/ Molecular bonds? I had a question thats asked for which had the highest Melting Point. Between NaF(s), NaI(s), NaBr(s),NaCl(s) answer: NaF -I get the fact that they're...

Hello everyone, So I know that I have to take two semesters of Ochem. I'm going abroad soon - but when I come back I have to do my capstone and complete some other hard courses. Personally, Organic Chemistry 1 - was really difficult, but I passed it. I have to take another semester of Organic...

I have an 8-book set of The Berkeley Review (TBR) MCAT review books, 2013 edition, that I am selling. I have 2 biology books, 2 organic chemistry books, 2 general chemistry books, and 2 physics books. There is some writing in the content review parts, but the practice sections are clean with no...

I am about to graduate college with a degree in chemistry, and I plan to apply to pharmacy schools this summer. Question: Is it reasonable to expect that one day I will be able to make money as a (retail) pharmacist part-time, and also teach chemistry at the college level? Background: My...

Hi! 1. I am looking for some clarification of the relationship between these concepts. hydrophobic/hydrophilic non-polar/polar negatively charged/positively charged acidic/basic I understand that a molecule can be any of the above. But I am wondering how these are related. From my current...

Can someone explain why the answer is A. The explanation says as the [C] of KI doubles so does O2. I don't see KI doubling in [C] and neither does O2 double in formation. For example, taking taking trial 2 and 3, the concentration goes from 0.060 to 0.090 does not double. And the formation of...

Hi! I was wondering what everyone's thoughts were on taking Organic Chemistry 1 and Organic Chemistry 2 in the summer ( during back to back sessions), such as taking Orgo 1 in session 1 and Orgo 2 in session 2 of the summer. The reason for me doing this is because a lot of the upper level...

Alright gentleman, Got a dilemma. Signing up for organic chem...only problem is my university has two. One set for Biology majors and another more in-depth for Chemistry majors. Which one do I take? If the chemistry major one isn't required for MD schools then I would like to take the one for...

“Removing water from H3PO4 (aq) + H2O (l) ⇌ H3O+ (aq) + H2PO4− (aq): Reaction shifts left. All concentrations would increase proportionately; because there are more products than reactants (and the stoichiometric coefficient is 1 for each reactant and product), the value of Q will increase.”...

Biology II w/lab Chemistry II w/lab Calculus I Microbiology

I've heard from some people that especially for chemistry, I should take as much as possible at my home institution. I have two classes worth of tuition credit for this summer and was thinking of taking a semester of chemistry (gen chem 1) and a semester of physics (physics 2), or two semesters...

Hi all, I'm pretty new here and this is my first post. Anyway, I need some advice, and it's a bit complicated but all advice is appreciated. I'm a freshman pre-med at a T-20 University (I would share the name, but I see people avoid doing that) and I've been struggling a bit. I got a B in my...

Hello everyone! I am wondering if anyone has taken Orgo 2 online through the University of New England. What would you suggest or recommend as preparation for the exams and labs? Thanks!

Hi guys, I wanted to get an input from anyone that has struggled with gen chem and orgo, and what resources they found that best worked for them? Been watching Chads Videos, as well as doing problems from destroyer, but in terms of starting from scratch and recognizing what ideally works, what...

While determining the s-character of an atom in a molecule, should I only pay attention to the hybridized orbitals? For example, in the following question, I knew that two orbitals were sp hybridized (and should have 50% s character) but I also accounted for the two unhybridized p-orbitals...

Im in achem and while the previous experiments have been individual labs, we are now doing group labs. The 2 other members are nice, but they keep on screwing up and causing us to start over or not finish in time. The first lab, one guy added in a wrong reagent (which he admits) in the middle of...

How important is it to be familiar with the more "esoteric" molecular geometries like "distorted tetrahedral" and "square pyramidal"? The Kaplan book doesn't really address them so I'm assuming they aren't particularly important but I just wanted a second opinion. Thanks!

So I was thinking, is it possible for me to take online gen chem 1 and 2 over the summer online in preparation for the rigor college will give me? I am aware that dental schools do not want to see that on my record, so I was thinking, could I take the course under my parents name instead? That...

thanks.

It's electronic configuration is: 1s2 2s2 2p6 3s2 3p6 4s1 3d5 So it technically only has one electron in the outermost (n=4) shell. However, the five 3d electrons do participate in bonding and I have heard of them being referred to as valence electrons. This may sound like a question of...

Hi guys, This may be a silly question, but I'm confused about the formula pKw=pKa+pKb (and I guess by extension Kw=Ka*Kb). My confusion came from an Examkrackers question asking "What is the pKb for HSO3-?" when given the pKa of H2SO3 (1.81) and pKa of HSO3- (6.91). The answer for the pKb of...

Hi Everyone! I am looking at taking some science pre-reqs for med school, to make sure I can handle them and also to (hopefully) boost my undergraduate gpa. Has anyone taken the following courses online through Athabasca, and, if so, what are your thoughts on them? BIOL 204 & 205 - Principles...

I wanted to take either biology or chemistry this semester but both courses were completely filled so my only option is to take biochemistry. I have never taken a chemistry or bio class. Would it be hard for me if i took biochemistry with no prior course knowledge of the information?

Bought the Dr. Collins for the January PCAT. It really helped me get the 90 percentile from 40 percentile the last time. Just send me a message if your are interested. Thanks

So my friend told me that she has been suffering with gen chem 1. She studies for days and knows how to do the problems but then the test comes and her brain shuts down. She forgets how to to finish the problems even though she learned the material already. Could orgo go better for her if she's...

Hello there. I know there are multiple threads out there with answers to questions that are similar to mine. However, I feel as though my situation is different and because of that, I could not seem to find a useful answer in any of the other threads. I am a freshman in College, and I am just...

Hi there! I am currently a freshman in college. For my undergrad University, I am not required two semesters of Calc, only one. I am thinking if I need to take calc II or if I will be fine not taking it for med school... Also, I am able to swap out the second semester of organic chemistry for...

So I am currently a freshman in college and I failed Chemistry 121. I want to know if it looks bad if I switch into Chemistry 111. Chemistry 121 is a fast pace course designed to do the traditional chemistry route in 3 classes instead of 4. Will I still be able to get into med school if there's...

Okay so I recently began studying for the DAT and plan on taking it Feb/March 2016. (haven't signed up yet). The books I have right now are: Cliff's AP Biology (PDF) DAT Destroyer '15 Math Destroyer '15. I have just gone over the biology section of DAT destroyer and have done 100 questions &...

Hey guys, Check out my blog to get help with chemistry and organic chemistry. www.coolchemtutor.com If you have a question you would like an answer and explanation to, you can snap a clear picture of it and send it to [email protected]. As soon as I answer it, I'll post it on my blog...

Is there a difference between polyatomic ions and polyprotic acids? I see that ions are ions and acids are acids but does polyatomic and polyprotic mean something different? Thanks!

Hi all, I'm about at my wits' end. I'm a freshman, and no matter how much I study, I never do well on my chemistry tests. I KNOW it's me, not the professor or the class, because, while many people fail the tests, there are always people who get in the low 90's, so I know I can do better if...

I don't know where to start.. Sooo I am currently about to finish my 5th semester at a community college. At the beginning of college I didn't really know what I wanted to do or felt extremely motivated to do well in school so I took my basic GE's and got Cs on almost everything. Last year I...

Hello, I am writing the Canadian DAT test in a few months. I have so far used Cliffs AP Bio and Ferralis Bio notes for biology review and DAT destroyer for bio and chem questions. I wanted to know if DAT destroyer is sufficient practice for the chem portion of the Canadian DAT. I know everyone...

Just out of curiosity, do med schools differentiate between engineering, chemistry, and other majors whose curricula would affect their science gpas? If so, how? I would imagine engineering, chemistry, physics and other physical sciences would have lower science gpas than health sciences.
