These are the ones that I found

Adiabatic Calorimeters.
Reaction Calorimeters.
Bomb Calorimeters (Constant Volume Calorimeters)
Constant Pressure Calorimeters.
Differential Scanning Calorimeters.

Usually atm is used!

405021651

I don't believe I've done any homework problems involving this but I am not sure yet:/

405021651

when K is less than 10^3

405021651

25 Celcius plus 273 to get the kelvin

405021651

The pKa is the -log(Ka)

405021651

It will be both outlines one and two!!!!!

405021651

I believe that there could be more than 3 but no more than 6 usually

405021651

because it is a pure liquid!!!!

405021651

Kp is dealing with the pressure not essentially the concentration like Kc is

405021651

Is this question in the 7th edition of the book?

405021651

All oure solids and liquids do not have to bee included I believe.

405021651

kg is in SI units , grams is not

405021651

The first bond is always a sigma and any bond thereafter is a pi bond

405021651

I would just count the number of electron densities

405021651

does a bigger radius mean a stronger acid or is it the other way around??

405021651

The molecular formula can still be divided down to get simpler values while the empirical can not be

405021651

yes! a double bond contains 1 sigma and 1 pi bond while a triple bond contains 1 sigma and 2 pi bonds so just add those up!!

405021651

count the number of electron densities then use "spppdd" and add one letter for each density. Ex. 1 region=s , 4 regions=sp^3, 5 regions=sp^3d

405021651

Bc the molecular shape of a square planer is octahedral with 90 degree angles then I believe thats why it should as well be 90 degrees

405021651

would the sigma bond be weaker one so therefor break first??

405021651

I believe its chapters 3.12-2.16 and 4.1-4.7 for the 6th edition in the book

405021651

Will it be only topics on outline 3?

405021651

The lone pair will take up more space so I believe its angle will increase while the other angles decrease

405021651

I believe It will be everything in outline 4

405021651

Lone pairs take up more space than a regular bond would take

405021651

Someone on a different post mentioned that it was on the week of November 19th and week 9 which is not making any sense now.

405021651

I'm sure more of the professors will post the slides so that will be helpful even without a bruin cast!!!!

405021651

Is there a group me for the group chat yet?*****

405021651

Is there a groupie group chat?

405021651

I believe that all of the charges on the atoms (not just the central atom) should be 0

405021651

I believe the number of bond that you should use is the number that would give you a 0 FC

405021651

A half octet also makes a stable atom?

405021651

Or will there be equal amount of questions from each outline?

405021651

Will there be more questions over outline #3?

405021651

But I have also seen different ranges of what is measurable or not but I would stick to that value from one of his videos

405021651

I believe that it was specifically mentioned that we should not use anything less than 10^-15

405021651

I do not believe he will ask us to memorize the shapes but we should understand them

405021651

I believe it is just everything on outline #2 so whatever information that includes

405021651

Thank you! So helpful

405021651

We will be given a formula sheet that will include those numbers!!

405021651

When will test 2 be?

405021651

I would stick to nothing less than 10^-15 because gamma rays= 10^-12 so he mentioned 10^-15 is safer than 10^-18

405021651

8 Questions for 40 mins? ahh

405021651

I think as long as we derive the answer we'll be fine but I'd use the one you're most comfortable with and for like tests just show your work regardless of the method

405021651

Thanks!
