chemistry

Hi guys, I wanted to know what I should do in this situation. I have 3 weeks until DAT and my main focus has become the sciences, primarily the Chemistries. I have already gone through, Cliff bio book and will be done with the destroyer within the next 3 days . While I am doing Ok on Bio, it...

To give everyone an idea of my application (mind that I'm a rising junior): Kin major/bio minor cgpa: 3.90 prereq gpa: 3.82 PRACTICE GRE scores: 152V 157Q Experience: 60 hours outpatient, 10 hours inpatient (I have two years of undergrad left so I plan on getting a lot more in about 3 or 4 more...

Hey guys, I was reviewing formal charges and came across what I originally thought was a straightforward problem (thinking otherwise now). The question is asking me to determine the formal charge on nitrogen in the following molecule: CH3-CH=NH2 I have been using the equation [# of valence...

Sorry, posted this in the wrong forum. Disregard!

Hi All- I have been trolling these threads of late (as I am sure many people do) as I begin my journey as a pre-med student. To give you all some background- I am a 25 year old student (non-trad) that just graduated from University with a Bachelor of Arts in Psychology. I did very well in my...

"Which halide will undergo SN2 reaction most readily?" I understand that all 4 choices suck, but I was between B & C when choosing the "most ready to undergo SN2". This is because I thought that even though tertiary halide is generally the worst scenario for SN2 to occur, you still get some of...

Hi I am a junior in High School and I plan to major in Chemical Engineering, and with that degree I want to go to Pharmacy school afterwards and work at a company like Pfizer afterwards. Is the degree that I want compatible for what I want to do? or am I completely insane. I absolutely love...

Has anyone taken these class with these professors at UC Berkeley Extension? Could anyone comment on the quality of professor and level of difficulty? I can't seem to find any recent threads on this... Genetics (online) with Susan Parkinson Immunology (online) with Monica Ranes-Goldberg...

Hello everyone, so I am trying to figure out my schedule for the second summer session at my university. I am currently signed up for General Chemistry 2 with the lab, but really want to get the physics I lecture out of the way before the regular school year starts. Is taking both classes...

Would biophysical chemistry count as a second semester of inorganic chemistry?

Hi Guys, So I've been preparing for the DATs using Ari's DAT Bootcamp guide, which if you aren't familiar, is a month of review using Chad's videos and AP Bio and the remaining 6 weeks will focus on practice tests and getting familiar with the actual test (using his software). I'm done with the...

Hey! :) First Question-- I'm aware that Chad is in some sort of dispute with course saver, but his videos are still on the course saver website. I wanted to purchase a 30 day subscription for his videos on course saver-- and tried multiple times to make a purchase-- but the website wouldn't let...

A lot of med schools are moving towards core competencies, thank god, but a fair number of schools still have hard and fast requirements, including two semesters of general chemistry. At my college, gen chem is a one semester course. What are my options?

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...
