CHEMISTRY COMMUNITY

505598869

Thank you for a great quarter of chemistry Dr. Lavelle!!!

505598869

The first thing I plan to do with my week off is get a haircut! It is self care time!

505598869

I am in the same situation and I do not think you can retake a class if you passed with a C..

505598869

What's done is done... after your test there is no point in stressing over your score.. it will come eventually.. in the meantime you should live your best life and not think about it

505598869

It should just be 14B material

505598869

I can not wait to be on campus!!!

505598869

Yes they are allowed

505598869

I would recommend Organic Chemistry Tutor on youtube! His videos really help me understand topics!

505598869

Thank you for this! This quarter has been crazy! Good luck to everyone!

505598869

I do not think there is a curve for this class.

505598869

Something that has been working for me is setting a timer for an hour (or less) and working until it rings and then giving myself a 15-30 min break and repeating that. This helps me stay focused and make the most of my time.

505598869

last quarter the final seemed much harder

505598869

I use my ipad to handwrite lecture notes using notability. However, I do not feel like my notes are beneficial. I never really use them after I write them. I like the idea soemone else mentions of typing the notes and hand writing the diagrams and I might try that.

505598869

Thank you! Just a little further! We can make it!

505598869

I honestly did not even know we had a week off for spring break. This is great!

505598869

I am nervous right now as a pre-med student because my chemistry grades are not that great and I don't know how that will effect me in the future...

505598869

Chem 14c, chem lab bl, and a media arts class

505598869

you can post in either section

505598869

I can't help but be nervous because after every test when I think I have done very well I have been wrong. And this time I didn't even feel like I did well..

505598869

I think ads long as you have 50 posts by the end of the quarter you will get full credit.

505598869

Congrats to everyone for getting through the week and Midterm 2! Time to relax!

505598869

Im taking chem14c and i am thinking about taking the chem lab bl but i am not sure...

505598869

Oh wow... praying for all my Texas people.

505598869

I don't think there will be a curve.

505598869

I didn't know wandavision was out already! I'll be watching that.

505598869

Im pretty sure 50% is a C

505598869

I am working but only on weekends so managing my time has not been too difficult.

505598869

Thank you Happy Valentines Day to you too!

505598869

I think it will be the bucks

505598869

The same thing happened to me... again.. I thought I did great on the test and ended up making a bunch of mistakes

505598869

Bridgerton was pretty good

505598869

I was wrong to bet against the bucks.

505598869

Thank you for sharing this.. this has really been a problem for me.

505598869

We did it! Wishing everyone the best!

505598869

Usually I spend at least 10 hours a week on chem.

505598869

I'm so nervous for my score but trying not to think about that right now.

505598869

Yeah, with the test over I can take a deep breath and relax now.

505598869

Last quarter I thought I did great on the first midterm and ended up missing easy problems. This time around I hope I did better.

505598869

I want to do good this quarter but my hopes ARGON... ahaha

505598869

Giveon has been a new favorite lately.

505598869

I'm glad I'm not alone with this.

505598869

My TA said that the test is during lecture on friday, and yes the TA's and possibly Lavelle will be on the call to proctor.

505598869

I would just do what works best for you whether that mean working on textbook problems a little each day or saving them until the end of the section. Personally I do them at the end of each section that way I know that I should have already heard from lectures everything I need to know to do the pro...

505598869

I have been enjoying reading lately. Sometimes I'll watch netflix if I have something good to watch.

505598869

Yes you do get credit even if you are not the first response.

505598869

I suggest focusing mainly on the outline problems and making sure you understand how to do them. Very similar problems are often on tests. UA sessions are helpful for a lot of people too.

505598869

Getting an A in chemistry

505598869

I would suggest studying, or doing practice problems immediately after watching lectures or discussions in order to put the new material to use and help it sink in.

505598869

Yes, temperature is the only thing that changes k.

505598869

The movie Soul on Disney plus was good!

505598869

I don't really watch much TV, but I just finished the Cobra Kai series on Netflix and it was pretty good.

505598869

Last quarter I think that every few weeks they would check how many total posts you have and just make sure you have at least 5 for each week of the quarter, but i am not sure so I suggest just keeping up with at least 5 per week.

505598869

The assignments are not always weekly, but it says on sapling when they are due.

505598869

I don't know if ALL the problems will come from the book, but I assume some will be either similar or straight out of the book.

505598869

My TA has stressed the importance of textbook problems, so I think knowing the textbook problems is the best way to prepare for the final.

505598869

Thank you for this! Good luck to you too!

505598869

Thank you!

505598869

Is there a way to contact Professor Lavelle directly? I don't see an email linked on ccle.

505598869

Hope you all had a good Thanksgiving!

505598869

I definitely find it more beneficial to do the assigned problems than the reading.

505598869

Textbook problems are my best friends at the moment... my only friends...

505598869

This is helpful. Thank you!

505598869

I'm doing well!

505598869

I stopped trying to read the textbook before starting the textbook problems from the outlines. At first I thought that we were supposed to read the chapters, but now I understand that it is almost never necessary and it is more beneficial to finish the problems rather than read. This is probably the...

505598869

After finishing my midterms I like to destress by finishing the essay assignment that I have not started before it is due at midnight.

505598869

I have to do well on midterm 2 I did horrible on the first one. I can't stop thinking about it. I need to know my score.

505598869

Another wise prophet once said, "It izz what it izz..."

505598869

You can use the one from the chem14a website.

505598869

Shrodinger equation is from the first midterm. It would not be on the second.

505598869

An easy way to find the number of valence electrons is by using the group that an atom is in. Group one atoms have 1 valence electron and those in group 8 (noble gases) have 8 valence. Do not count the d block while counting the groups.

505598869

I will be rewatching lectures, redoing textbook problems, and going to as many UA sessions as I can.

505598869

I ain't never seen two electrons with the same 4 quantum numbers. Always one of them gotta be different.

505598869

I think my hopes of getting an A in this class Argon at this point.

505598869

It would be nice to have people to study and work with. If anyone is part of a smaller study group with a group chat or group calls to work on homework and study let me know. I would like to join.

505598869

This is confusing, I have heard both that the class is curved and that it isn't.

505598869

Yes, I am stressed about my grade right now because I did very badly on the first midterm and now I have to save my grade. My TA says I have nothing to worry about, but I think she is just trying to be encouraging.

505598869

Yes, this midterm can include the rest of outline 2 and outline 3.

505598869

Yes, by now I think you should have received points for chem community participation.

505598869

I stayed home with family and started watching Cobra Kai on Netflix.

505598869

I fooled myself into thinking I had done great on the midterm... then I saw my score.

505598869

I am going to try going to more UA sessions. I feel like I must be missing out by not going.

505598869

I just want to get back on campus. I thought online classes might be ok, but I'm not enjoying it.

505598869

I did not do well on the midterm and I am very disappointed... I felt very good after taking the test and thought I had done well. I did a lot of studying and felt like I was well prepared for everything on the test. I do not know what I could have missed but now my goal is to figure out what went w...

505598869

Yes, it is possible but I do not think we will see much of that in this class.

505598869

Both the atomic and ionic radii increase down a group and decreases across a period.

505598869

m(l) depends on the value of l. If l=1, then m(l) can equal -1,0, or 1.
If l=2, then m(l) can equal -2,-1,0,1,2.

So if the problem says that n=2, l=1, m(l)= 1
then it would be referring specifically to the "2pz" state.

505598869

This means that there are five orbitals in a d sub-shell. Since we know that one orbital holds two electrons, and that a d sub-shell can contain up to ten electrons, we can say that ten divided by two is five. Therefore, there are five orbitals in the d sub-shell.

505598869

Atomic radii increase down a group and decrease across a period.

505598869

This is depends on the type of metal being used. Different metals will have a different threshold energy requirement for electrons to be removed.

505598869

wavelength(lambda) = planck's constant(h) / momentum(p)
p = mass x velocity
you can plug in mv for p in the wavelength equation and isolate v
you would end up with

v = h/m(lambda)

505598869

It depends on what units the problem asks for. You might have to convert depending on the answer choices when it is multiple choice.

505598869

I would use whatever numbers Dr. Lavelle gives us on his constants/equations sheet.

505598869

The DeBroglie Equation shows that objects with a very little mass have wavelike properties that are identifiable and measurable.

505598869

If the photons of the light reach the threshold energy level required to eject electrons from the metal surface, then increasing the intensity of the light will result in more electrons being ejected. However, if the photons do not reach the threshold energy requirement, the intensity of the light w...

505598869

Reagent is just another word for reactant. They are the same thing.

505598869

Yes that are the same. They both equal the amount of energy required from a photon to remove an electron from the metal surface.

505598869

Lavelle said that since it is more a physics topic than a chemistry one, we won't discuss it in depth.

505598869

You should try to find one on amazon.

505598869

I think lectures are going to be recorded and I like it because you can pause and rewind whenever you need to.

505598869

Chemistry jokes are Na funny.
