chemistry

confused about this one: If an acid is weak, thus giving off less particles, wouldn’t that make less of a difference on the boiling/freezing point? Because the vant Hoff factor would be a smaller number... Explanation says: “HClO would be the weakest acid thus giving the fewest particles...

The Kaplan book for Orgo mentions that the Gabriel synthesis uses a very bulky nucleophile (phthalimide) for the Sn2 reaction with diethylbromomalonate. The book mentions that "the bulkiness of the nucleophile creates steric hindrance, which prevents the substrate carbon from undergoing multiple...

Hello! I am a senior in high school and have always wanted to do nursing as my career because helping others is just extremely satisfying to me. However, I’ve also taken chemistry classes in the past year, and I’ve realized I also enjoy learning and doing chemistry. It has accomplished lots for...

I was wondering why histidine < lysine < arginine are in this order of increasing basicity, if histidine has a more stable conjugate acid (protonated form) due to resonance?

I just switched into the pre-med track (woohoo) and am now finding out that a lot of medical schools don’t accept AP credit (boohoo). Since my undergrad institution accepted the AP credit as General Chemistry 1 & 2, I went straight into Organic - did 2 semesters of that and then a semester of...

Question: In a sealed 1L container, 1 mole of nitrogen gas reacts with 3 moles of hydrogen gas to form 0.05 moles of NH3 at equilibrium. What is the Kc of the reaction? The balanced equation is N2 + 3H2 -> 2NH3 The solution says that we would have (1-x)M of N2 and (3-x)M of H2, to get the 0.05M...

If this is in the wrong place, please help me out! I'm currently in gen chem 2 through the University of New England online program. My score in the class is in the upper 70's. The professor says this is "above average" but won't tell me if there's a curve or not. If it's curved and I am in...

My book (Kaplan MCAT Gen Chem pg 27) says that for the sulfur atom in the sulfate ion, sulfur's 3s and 3p subshells can only contain 8 of these 12 electrons; the other 4 electrons have entered the sulfur atom's 3d subshell, which in elemental sulfur is empty. Why did "the other 4 electrons"...

Hello everyone! I am going to be a Junior in the Fall and will be taking Biochem I. At the college I attend, Biochem I is one of the toughest classes haha. I was wondering what advice you guys have for studying Biochem? Those of you that did well in it, what should I go in expecting? Lots of...

As a Year 12 student in the UK, I've been researching all the medical schools and their requirements for a few months already. But when I decided to do further research around January, I found out that some schools required Biology as a compulsory A-Level, as mine were Physics, Maths and...

I will be a junior in the Fall taking these courses: Genetics - 4 Biochemistry I - 3 Genetics Lab - 3 3 credits of research (not for a class, or even for a grade) and 3 credits of... Spanish maybe? Some easy course Would this look weird? It would still equate to 16 credits, but would it...

i was looking at the application and several schools require Inorganic chemistry? Is that their way of saying Gen Chem?

Just a quick question I know that the MCAT is more about UNDERSTANDING rather than MEMORIZING. However, do we have to memorize for formulas for Planck relation (E=hf) or angular momentum (L=nh/2pi). Yes, they are not too hard to memorize but I just want to know how much details I should know...

OK so... I took a Stats lab course and at the college I attend the course is labeled STA L. But it’s in the psychology department at the college I attend... so does it count? It’s one credit Also, for some psych courses the course code is PSB... does this count? And PCB is for genetics. Does...

So two semesters ago, I took Bio and the Lab. I got a D in Bio and a C- in the Lab. I’m retaking the Bio right now and it’s going well. Is it worth retaking the lab? I know that a C is required for many different med schools and I’ll surely retake the course but would it be OK to retake it at a...

I've taken biochem 1 at my university and received an A. I believe I have a pretty solid understanding of all the material in it. Should I take biochem 2 as well? Or would it be unnecessary? Any thoughts or opinions would be appreciated. Thanks.

Does the DAT emphasize more content from Gen Chem 1 or 2? And what do they generally provide for that section? Do they provide all the formulas or do you have to remember them? Solubility rules? Polyatomic ions etc.? Thanks.

So I’m having some trouble getting the full A in Bio courses. I’ll either get an A- or a B+. But was wondering how to really get that A? How do all of you do it? I average low A’s and high B's on the exams and do decently well overall in the coursework, but I always come up short with an A- or a...

Will I be able to get into dental school with a C in both gen. chem. 1 and 2? I'm worried that my grade in Gen. chem will prevent me from getting admitted into dental school. Should I just give up and choose a different career path?

Hi, I am currently a sophomore in college and have taken general chemistry, physics, English, psychology, sociology, mathematics, and some statistics courses. I will be taking biology and organic chemistry in my junior year, genetics the summer before my senior year, and taking the yearlong...

I’m a freshman majoring in biology hoping to go to med school or grad school. I just got an F on my second gen chem 1 exam, my first failed college exam. I got a C on the first one. My overall grade is a C because of the homework and there’s still 2 more exams left. I studied harder for this...

I have scoured the site and was unable to find some assistance, so I have to post this, I know it may be a little off topic and not entirely helpful to others, but I need some help. This is my second time taking Chemistry 2 and I just found out I failed the second test of 4, meaning I am not...

Are the graduate students and TAs in research known to be a little rude? I’m working in a lab and feel a little patronized. I could just be super sensitive but I was wondering if that was known to happen. The TA I’m working with just seemed a little dry. Note, I am not complaining. I’m still...

Hello everyone, I'm curious about the BCPM GPA. I understand that it is Biology, Chemistry, Physics and Mathematics but do Psychology courses count as well? I am a Neuroscience major, so naturally I have to take a lot of upper division Bios and Psychs. But I'm wondering because I am doing well...

Hello, Considering doing a BA in Chemistry ... Does it look unfavorable to not get a BS? Thank you so much

Since systems move from a low number number of states (lower entropy) to a high number of states (higher entropy)- following the second law of thermodynamics. How does the protein folding move from a high number of potential folding configurations to its theoretical local state follow the second...

I want to pursue an EMT certification. I was looking at some online. I found one at "RC Health Services". I was wondering if you guys found this to be legit? I find it to be very interesting. It is done online but could it be fraudulent? What do y'all think? Has anyone ever done this before...

I took Organic Chemistry 1 this last semester (with the lab) and received a D in the lecture component and a C- in the lab. I am re-registered for the lecture, but am wondering if it is really necessary to re-take the lab. While I understand re-taking it and getting any grade above the C- would...

Just wondering if any of you have seen Genetics as a prerequisite for MD schools? I did some research and it looks like it depends on the school so would it be a good idea to take it anyway? I don't have to decide this now, as I will probably be taking Genetics next Fall. Any advice or input...

Hi guys, I Feel like I have a solid background on all subjects the MCAT covers besides gen chem. I got C's in gen chem 1 and 2 (wasnt really motivated my freshman year). All other pre-reqs I got A's. I will dedicate about 3 months of self study to MCAT. How long would it take for me to get a...
