Matlynn Giles 2E

The anode will always be oxidized and the cathode will always be reduced

Matlynn Giles 2E

F is a nucleophile

Matlynn Giles 2E

This would cause third order reactions.

Matlynn Giles 2E

I am pretty sure it is because they used ln rather than using log.

Matlynn Giles 2E

reversible interactions have to have deltaS (uni)=0 so the deltaS of the surroundings is equal and opposite the deltaS of the system

Matlynn Giles 2E

Catalysts do not shift the equilibrium.

Matlynn Giles 2E

Go to reviews! SO HELPFUL!

Matlynn Giles 2E

Yes! Those are all state functions!

Matlynn Giles 2E

Can someone please elaborate on this?

Matlynn Giles 2E

A mug with a lid would be an example.

Matlynn Giles 2E

I'll be taking 14BL and 14C together next quarter.

Matlynn Giles 2E

amount of heat generated in a reversible process

Matlynn Giles 2E

I attempted this problem without using the list and it's virtually impossible.

Matlynn Giles 2E

H2O2 + 2OH- --> O2 + 2H2O + 2e- is how I did it!

Matlynn Giles 2E

Yes they do!

Matlynn Giles 2E

you should find the moles of Na2 by using moles of NaN3

Matlynn Giles 2E

both equations are used to find entropy, just in different ways

Matlynn Giles 2E

no units assigned to it!

Matlynn Giles 2E

two different things but an equation can relate the two!

Matlynn Giles 2E

number of ways of achieving a given energy state

Matlynn Giles 2E

I believe this has to do with the protons, neutrons, and electrons of the system.

Matlynn Giles 2E

I'm thinking jsut the names are different but no substainable difference

Matlynn Giles 2E

ender and exer for gibbs. endo and exo is for enthalpy

Matlynn Giles 2E

Has he posted an outline yet?

Matlynn Giles 2E

Does anyone have any advice if we should first pass 14c or not?

Matlynn Giles 2E

Wow this is so cool! I've definitely noticed it applying in real world too!

Matlynn Giles 2E

refer to the natural form of the element...

Matlynn Giles 2E

E- pushing down on piston
I- aganist piston

Matlynn Giles 2E

Isolated system!!!

Matlynn Giles 2E

Does anyone have any specific TA review sessions they reccomend?

Matlynn Giles 2E

What date is the final?

Matlynn Giles 2E

Because there is a loss of heat.

Matlynn Giles 2E

Anything less than 10^-5 you can use estimations for.

Matlynn Giles 2E

I would think we would just be using this equation for molarity and pressure.

Matlynn Giles 2E

Will work be on the midterm? I didn't think so but I was at a review session yesterday and someone mentioned it.

Matlynn Giles 2E

Do we know if the Midterm is all multiple choice again or will there be free response?

Matlynn Giles 2E

How long can we expect the midterm to be? how many questions

Matlynn Giles 2E

I had this same issue. It turned out to be a typo.

Matlynn Giles 2E

How do you know when to have a +X or a -X in an ice table?

Matlynn Giles 2E

On Sapling HW question #2 I have my Ka as .000429 with .142M of acid. Everytime I use the quadratic formula I recieve an error.

Matlynn Giles 2E

Do we always use HA yields H+ + A- when talking about a weak acid? What do we use for a weak base?

Matlynn Giles 2E

the concentration of no decreases by 2x! no and o increase by x

Matlynn Giles 2E

Q>K means that the ratio is higher than the equilibrium ratio.

Matlynn Giles 2E

The principle states that after heating the products, the reaction favors the reactants to restore equilbrium.

Matlynn Giles 2E

I believe he gives us constants as well as formulas on the exam.

Matlynn Giles 2E

I have attempted this problem 8 times and I keep coming up with the same answer (.61) and I am keep being told it's wrong. can anyone help? thanks!!

Matlynn Giles 2E

As the pressure increases the equilibrium will shift to the side with fewer moles

Matlynn Giles 2E

Pressure, Volume, # of moles, gas constant, temperature

Matlynn Giles 2E

The best way I've found to remember this is Q stands for quotient!

Matlynn Giles 2E

The reaction will shift as a way to react/adjust to changes!

Matlynn Giles 2E

The concentrations aren't the same, just the reactions!

Matlynn Giles 2E

I too generally always forget to divide by the moles of the contianer. Sometimes it helps to think because it's so small!

Matlynn Giles 2E

Can any explain protanation of strong acids and strong bases?

Matlynn Giles 2E

So the stronger the conjugate base, the weaker the stronger acid?

Matlynn Giles 2E

Do we have to memorize pKas or Kas of strong acids?

Matlynn Giles 2E

On the final will we be required to have a calculator to calculate for strong acids and strong bases?

Matlynn Giles 2E

IS any deriavtive of a strong acid, a strong acid?

Matlynn Giles 2E

Just because something is the same element does not mean they're the same! He talks about this in his lecture about chemothearpy. I believe it was Monday's lecture of week 9.

Matlynn Giles 2E

I would try looking at the ligand sheets or quizlets to help with naming ligands! Found it super helpful!

Matlynn Giles 2E

Dr. Lavelle may have said this but are there partial credit questions on the exam?

Matlynn Giles 2E

Hi! I have found that there are numerous quizlets to help memorize the ligands.

Matlynn Giles 2E

Will the final be similar to how the midterms were conducted? Will we need a secondary device to video?

Matlynn Giles 2E

Does anyone have a list of the UA sessions? Are they the same thing as step-ups. Not really sure what they are.

Matlynn Giles 2E

Will the Final be administered during Discussion like the previous two midterms?

Matlynn Giles 2E

I too have the same question/concern. Do we know if he'll be sending out a message to acknowledge this?

Matlynn Giles 2E

Does anyone know forsure if 14B midterms will be adminsitered during class time? Should we not have it overlap with another lecture?

Matlynn Giles 2E

Does anyone know how to get in personal contact with Dr. Lavelle? Looking to set up a 1-on-1 meeting. Thanks!

Matlynn Giles 2E

Does anyone know if 14CL is required for med school or just 14BL?

Matlynn Giles 2E

Do people usually take 14B and 14BL together or 14C and 14BL together? Any suggestions?

Matlynn Giles 2E

I would assume the scale has somewhat changed because you need such a low percentage to obtain a C.

Matlynn Giles 2E

If we didn't first pass 14B and all of the waitlists filled, will we still have an opportunity to take the course?

Matlynn Giles 2E

Will the final be the same style as the first two midterms?

Matlynn Giles 2E

I would assume it would be the same format as Midterm 1. I am going to attend his office hours this week so I can double check.

Matlynn Giles 2E

How do we know what atom to put in the center?

Matlynn Giles 2E

Are elements that reside in Group 13 electron dependent? Thanks!

Matlynn Giles 2E

What does the symbol that sort of looks like an S when we're referring to electronegativity stand for?

Matlynn Giles 2E

I'm a little confused how a molecule can be both ionic and covalent. Can someone elaborate on this for me? Thanks!

Matlynn Giles 2E

Does anyone know the breakdown of midterms and the final? How much percentage is the midterm and the final that contributes to our grades?

Matlynn Giles 2E

For the Heisenberg Equation do we use psi or psi squared?

Matlynn Giles 2E

Not sure if anyone's run into this problem but I'd thought I would share because it continuely happens to me. By using parantheses on everything you insert into your calculator, it really prevents errors. Especially in terms of determining if an exponenet should be negative or positive

Matlynn Giles 2E

Does anyone know how to see if we've been receieving points for posting on Chemistry Community? Thanks!

Matlynn Giles 2E

Do we know if Midterm 2 will be the same strcuture as Midterm 1? 12 multiple choice?

Matlynn Giles 2E

I am a little bit confused as the what p stands for in this equation and when to use it. Thanks!

Matlynn Giles 2E

I always find Khan Academy helpful especially when needing to review more basic concepts such as strong acids and bases. I also attended a Step-Up Session last week that was soooo helpful! Hope this helps!

Matlynn Giles 2E

I've been so stressed about school so this such a relief. It is so nice to see that someone is doing so well and so happy. Thanks so much for sharing! It means the world to us!

Matlynn Giles 2E

Do the 0's following the decimal place count as SigFigs? For example the 2 0's after the decimal in 20.00.

Matlynn Giles 2E

When will our final grades from the midterm be posted? Also, I heard someone say Lavelle may be offering partial credit? How would that be the case because they are multiple choice?

Matlynn Giles 2E

Hi! Me and a few other students are slightly concerned that we have a disadvantage in terms of Midterm 1. My discussion is on Tuesday whereas other students have discussions up until Friday. Those students have more time to study. Is there anyway to change the midterm that way all students in Chem 1...

Matlynn Giles 2E

For all of those asking about Black Body, I am pretty sure Dr. Lavelle said not to worry nor stress about it for the exam.

Matlynn Giles 2E

Did Dr. Lavelle ever say what we should use for Sig Figs? Will we get points marked off for using too many or too little? Thanks!

Matlynn Giles 2E

What is the structure of the midterm? Multiple Choice? Short Answer? All individual? Thanks!

Matlynn Giles 2E

Does anyone have any reccomendations for a camera? And are they reccomended or required? I have a 13-inch MacBook Pro. Thanks!

Matlynn Giles 2E

When solving for E, should we use E=pc or E=hv=h(c/wavelength)

Matlynn Giles 2E

What does keV stand for? I never heard it in the lecture but it was brought up in lab.

Matlynn Giles 2E

Would Gamma Rays, X-rays, or Ultraviolet Rays be stronger?

Matlynn Giles 2E

Can someone explain how to balance equations when there is an odd number of elements? Do we use a mixed number?

Matlynn Giles 2E

How would you determine if the empirical formula is actually the empirical and not the molecular?

Matlynn Giles 2E

Specifically for Dr. Lavelle's class, how many sig figs should we be using? To the right of the deciemal point, how high should we go up?

Matlynn Giles 2E

In number 10 of the Week 1 HW, I know Avogadro's Constant is needed to complete the problem but I am unsure how. Is there a way for someone to show me how? Thank you!

Matlynn Giles 2E

Will the formula Minitial x Vinitial = Mfinal x Vfinal be used for every dillution? I thought in highschool we learned different formulas but I can not remember.
