Where do we find the information about the plfs is it with the review session info?

do you know why this is the case?

allisoncarr1i

Does he add to this as we start learning more equations and concepts or is this all of the equations for the quarter?

allisoncarr1i

so does getting 50% of the points mean you will pass the class regardless of the class average?

allisoncarr1i

The slides should be online soon

I believe it was 80%

allisoncarr1i

Is lyndon's review on the list of review sessions on the website or is that separate?

allisoncarr1i

Homework problems and review sessions are the most helpful

allisoncarr1i

The review sessions started the saturday before week 10

allisoncarr1i

Does that line in the syllabus also mean that anyone who receives over 50% of the points will pass?

allisoncarr1i

No one has said anything about it yet but I'm sure when he does it it will be announced in lecture

allisoncarr1i

lower case k is the boltzmann constant and upper case K is the equilibrium constant

yes that is correct

yes only two tests for this quarter

allisoncarr1i

Jchellis 1I wrote:Was this covered in class? Or were we just expected to know it?

It was mentioned in the homework problems for this section.

allisoncarr1i

is there ever an instance where both would lose an electron?

Jchellis 1I wrote:What does the single line represent then? I thought the single line was the salt bridge?

the salt bridge is usually shown as a double line when we draw the figures

allisoncarr1i

Jchellis 1I wrote:Are significant figures something we are being graded on right now? It seems like he had been pretty relaxed about them recently.

They weren't worth anything on test 2 but i don't know if they will be for the final.

allisoncarr1i

I'm pretty sure you are allowed to turn in any problems from the syllabus as long as you haven't already done them.

allisoncarr1i

I believe the newer sections are more heavily emphasized on the final.

allisoncarr1i

Thank you so much this was very helpful!

allisoncarr1i

The approximation can only be used if K is very small.

allisoncarr1i

Any element that is in its liquid or solid form can be disregarded.

Hilda Sauceda 3C wrote:In sessions who does the questions step by step even if they seem obvious?

The step up sessions are best if you're looking for in depth explanations on every level of problem or concept even ones that might seem basic.

I believe the step up sessions aren't as rigid with sticking to a certain topic and will accommodate any questions you have.

allisoncarr1i

The first two outlines will be included on test one.

allisoncarr1i

Does anyone know why they are not included or is it not necessary to know why?

allisoncarr1i

K and Q must be equal which indicates that the reaction is occurring at the same rate forwards and backwards.

allisoncarr1i

The partial pressures and concentrations do not have to be at equilibrium for Q but they do for K. Other than that, it's the same equation.

Ashley P 4I wrote:You two are life savers, thank you for simplifying this. Lone Pairs= Base No lone pairs= Acid

Are there any exceptions for this or is it pretty reliable as a quick way to determine whether it is a base or acid?

allisoncarr1i

Amphiprotic substances can accept and donate protons, amphoteric substances can act as both an acid and a base. All amphiprotic compounds are amphoteric. A clue to determine if a substance is amphoteric is to first check if there are hydrogens/protons to donate in the substance. If not, the substan...

Is this due to the difficulty of breaking those bonds or for a different reason?

allisoncarr1i

It covers all concepts on the outlines on the website and includes questions from homework and his pre and post module assessments as well.

allisoncarr1i

Is it likely that concepts we have not been tested on before would be more likely to appear on the final?

allisoncarr1i

Can the evaluations be done after the deadline or are they no longer available?

allisoncarr1i

Jchellis 1I wrote:Is he going to emphasize the material after the midterm more or will it be more equal?

He has said in class that everything on all of the outlines is equally likely to show up on the final.

allisoncarr1i

So will everyone between 50% and 73% all get a C- regardless of their actual percentage?

allisoncarr1i

I haven't heard anything about specific final review sessions but the test 3 review sessions and step up workshops will definitely be useful resources for final prep.

allisoncarr1i

According to the announcements on the class website, test 3 will cover the end of Bonding from 3.12 (6 Ed.) and from 2D (7 Ed.); and all of Molecular Shape and Structure.

This would probably depend on your TA but since the Thursday and Friday discussions won't be meeting I doubt any of the TAs would have mandatory discussions that week.

allisoncarr1i

Some of the TAs have said that the midterm will be handed out after lecture on Wednesday/

allisoncarr1i

There are multiple step up programs and workshops as well as office hours that you might want to try before looking for an outside tutor who might not be as familiar with the specific material we need to know.

allisoncarr1i

They definitely would not schedule a make up exam for a class conflict and honestly it's probably too late for any accommodations to be made anyways sorry.

It might depend on the TA because pen was not required for some TAs on the previous tests.

Megan_Ervin_1l wrote:Are we doing any 7 problems we want that are listed? Or do the problems have to come from all sections?

We can do any 7 questions from the section(s) listed for the topic that week on the syllabus.

allisoncarr1i

Khan Academy is helpful for reinforcing the topics we discuss in class and is also useful for hearing the concepts described in a different way which I have found makes it easier to retain and understand the information.

allisoncarr1i

The video modules are much more helpful and understandable than the textbook.

allisoncarr1i

The TA is most likely just going to input all of the information at the end of the quarter but I'm sure you can ask or email them if you are curious about your grade throughout the quarter.

allisoncarr1i

It seems to be different for each TA based on what people in this forum are saying so you might want to double check with your TA or others in your section.

allisoncarr1i

I find it most effective to type notes in class so it is quick and can be accessed and sorted through easily on my google drive and then recopy the notes to help with retention.

allisoncarr1i

My TA said Sunday night but I know a lot of others have been saying Friday so it probably just depends on when each different TA is checking.

allisoncarr1i

For the in discussion tests it depends on the TA but for the exams I doubt he'd be strict on it as long as your writing is clear but you might want to ask someone who's taken the course before.

allisoncarr1i

They are given on the exams but it might be helpful to familiarize yourself with some of the more frequently used constants just as a time saving technique.

allisoncarr1i

Thank you so much for these! Is the difficulty level similar to what you'd expect from the exams in this course?

allisoncarr1i

All of the textbook solutions in the solution manual round up when dealing with calculations ending in 5 so I would definitely say that's the way to go.

allisoncarr1i

I would recommend taking advantage of the peer learning for brushing up on the subjects you are rusty on. For more in depth walk throughs and explanations Khan academy is extremely helpful.

allisoncarr1i

Do you have to sign up for the peer learning sessions or can you just show up during the hours listed?
