Re: grade worries
i am also reqlly worrried for grades because I don't know if anyone else had this problem but chem community was so hard to navigate for me. A couple of times I ended up on the Chem 14B section and so I just gave up on it for a while and now my anxiety about grades is starting to creep back up on me...

Re: unit conversions
does anyone have any useful tips for converting SI units for the final or is it just straight up practice makes perfect kind of thing ?

Re: Advice from a Medical Student [ENDORSED]
thank you so much for your advice! But as someone who is struggling in this class and fears that will not do good, do you have some tips on how to improve from here on forward?

Re: Chem 14B Enrollment
Definitely monitor the class as enrollment progresses because during my first enrollment it looked like the class was not going to be filled up but I used it anyways because I really wanted to and my other classes were not as essential. By the time the day my enrollment finished it was filled up. I ...

Re: Photoelectric effect [ENDORSED]
for part a, would you use some form of variation id c=(lambda)(frequency) ? This and the following question relates to the same metal used in a series of photoelectric experiments. A. If 3.607 x 10-19 J is required to remove an electron with zero kinetic energy from a metal surface, what would be th...

Re: How to calculate the kinetic energy, energy and frequenc [ENDORSED]
for part B, is there any particular reason why we should divide by Avogadro's number? I thought that the work function was the minimum amount needed to free the electron so that it would be a given? The steps to solve the problem are: 1. Use Ek = 1/2 mv^2 2. 2. Divide the total energy (work function...

Re: How to calculate the kinetic energy, energy and frequenc [ENDORSED]
So for part A, are there any additional steps to take after doing the 1/2 mv? Because I did that and I got a fairly large number that wasn't any of the options but I don't know where I went wrong. The steps to solve the problem are: 1. Use Ek = 1/2 mv^2 2. 2. Divide the total energy (work function) ...

Re: Step Up Sessions
Does anyone know if the host of step up sessions post the worksheets on chem community? I can't make the sessions but would still like the extra practice on my own

Re: studying for exams
is there a specific link where we could find additional problems to study for midterms or should the hw problems and textbook problems enough ?

Re: WK 1 Sapling #10
I also had questions about balancing that equation / assuming it was balanced. I googled 3‑methyl‑3‑hexanol, which I think just confused me more. But assuming it is balanced how were you guys able to tell? This might be repetitive sorry but I'm just trying to understand.
