Does somwone have a chart/graphic they used to help memorize this?

Does anyone have a particular website/youtube channel/study site(something like quizlet or study blue) they want to plug?

The Arrhenius equation shows the temperature dependence of reaction rates: https://www.gstatic.com/education/formulas/images_long_sheet/arrhenius_equation.svg The textbook is showing how to derive van't Hoff equation from the Arrhenius equation by relating the temperature dependence of reaction rat...

Does anyone have an idea how important acids/bases will be on the final?

Mai V 4L

You should end up with the same result, i guess we just always try to pick out the easiest choice What makes it the easiest choice, like how do you know Sometimes some concentrations are easier to work with than others. For example, say trial 2 is just double trial 1 while the third trial is some r...

Mai V 4L

it is based on the size and how complicated the structure is. If there are two molecules of equally complex structure then the larger one has higher residual entropy bc more atoms=more electrons and electrons are always moving around so they have many different possible states. if its 2 diatomic mo...

If you are referring to Lyndon's review packet, then usually he tells a special code name that we can type into chemistry community and find the review packet under like "marshmallow" (it's different every quarter). You won't get an actual packet at the review session. Either you can prin...

IMG_0853 2.jpg I drew them out so that it's easier to visualize the 12 cis and the 3 trans in case anyone is also struggling like me; the above comment definitely helped me understand this problem a lot better, thank you so much! I circled the X so that it's easier to see how each molecule differs ...

Why is it not available? because it becomes disoredered? or exhaust?

IF they pass one out would anyone ming sharing an electronic copy for those not able to attend?

When reaction is irreversible free expansion, delta S total equals delta S of system, and delta S of surroundings is zero.

Quoting this so I can access it easily

Jacob Puchalski 1G wrote:The third law of thermodynamics is basically as the temperature reaches absolute zero (0 Kelvin) then entropy will also decrease to zero.

Can you please explain why

Mai V 4L

Will this be on the final exam formula sheet?

Brian J Cheng 1I wrote:Pretty sure some of the exams should have the solutions already on them as they can be student submissions of old exams

Sadly the bruinbank website has only blank copies online :-//

Mai V 4L

Also, if it becomes take home, when do you think they'll let us know??

Mai V 4L

Where'd you get your book from? Mine was loose leaf so maybe thats why I didn't get sapling access, not sure though

Mai V 4L

Was looking at the test bank old final and it hobestly didn't look too much like what I thought it would be

Mai V 4L

I felt the same. But I recommend watching videos to really instill the material covered in class so that you can apply them to solving problems. I also recommend doing the Sapling problems if you can because it builds you up to solving difficult questions. Ca you please share the link to these vide...

Mai V 4L

Does anyone have solutions from another source they think are pretty spotless?

Mai V 4L

Does anoyne know where to find the solutions for the exams in the test bank? THank you

Mai V 4L

Is the only place to get a copy at a session?

Mai V 4L

I made a google sheet with links to all my posts just helps to keep track of how many

Mai V 4L

Can someone please give me a quick rundown on this or send a link to a resource? thx

Mai V 4L

Does anybody have a good youtube video for explaining this?

Mai V 4L

Does anyone have any recommendations on digital flashcard websites/apps besides quizlet or study blue? Preferably something free that works on computers & mobile Thanks!

I found that this video gave a quick, comprehensive definition of amphoteric molecules with examples: https://www.youtube.com/watch?v=_t_4cCi8jiI

Thank you!!!!

Mai V 4L

an someone please give me a quick rundown on this or send a link to a resource? Thanks

Mai V 4L

Will the test focus more on the first or second half of the class? (take home final sounds kinda lit)

Mai V 4L

Thanks for the feedback! I'll try to just stick to K

K=Ae^-Ea/RT where A is the frequency factor or pre-exponential factor (indicates # collisions with correct orientation)

Thanks!!!

Mai V 4L

Can someone post an example of this notation pls

Mai V 4L

Can q be constant in this case?

Mai V 4L

This means q stays constant right?

Mai V 4L

Does anyone have a chart/trick for remembering this?

If anyone has any good examples from the book please share!

Will we have to know this on the final?

anyone got any tricks to remember these? having a hard time!

Do y'all think this will be on the final?

Can you elaborate please?

Mai V 4L

Will we have to define this on the final?

Mai V 4L

Will we need to be able to write the Arrhenius acid/base definitions on the final?

Can someone please share an example of a problem in which we'd have to exclude reactants/products not in the gas phase?

Mai V 4L

Piggybacking on OP, yeah how likely are we to find K that is "large" or "small" in the real world?

Mai V 4L

Hi all! When doing work for the test, let's say I forget to use a subscript at some point when I am calculating K, how much will that count against me? Also does anyone have any tips for remembering specific subscripts? Thx
