They can be used interchangeably

Ronald Thompson 1F

Yes it is useful to know how to use them.

Ronald Thompson 1F

Usually around 8 but they will be multi-step problems.

Ronald Thompson 1F

There will most likely be a pretty fair distribution of content, but leaning more towards thermo and kinetics

Ronald Thompson 1F

They are checked but will not be super important. Just a couple points per problem

Ronald Thompson 1F

The deadline ends tomorrow for submissions. But I would assume you could post after the final as well

Ronald Thompson 1F

They increase the speed of a reaction

Ronald Thompson 1F

Agreed, the test was challenging

Ronald Thompson 1F

isolating t1/2 and halving A should get you the half life with some calculus.

Ronald Thompson 1F

He noted that we were ahead of schedule, so I would expect anything and everything to be covered in that regard.

Ronald Thompson 1F

It will likely tell you if it isn't clear

Ronald Thompson 1F

We wont be tested on that

Ronald Thompson 1F

Going over lecture notes, making sure I understand key concepts, and then just nailing homework problems.

Ronald Thompson 1F

If not given, which it usually is... us 25 degrees C or 298 K

Ronald Thompson 1F

Is it thermodynamics after the midterm or inclusive of all thermo?

Ronald Thompson 1F

Yes, It is.

Ronald Thompson 1F

q can also equal -w.

Ronald Thompson 1F

You will not need to solve integrations. Just know what equations you get from the integrations. Those are applicable to different questions and the circumstances

Ronald Thompson 1F

Check Lavelle's website for all updates, review times, and more

Ronald Thompson 1F

Is there a solutions guide as well?

Ronald Thompson 1F

You have to look at the number of different arrangements of atoms. Best way is to draw lewis structures

Ronald Thompson 1F

Steam at 100 degrees gives off a lot more heat, thus burns more. There is a chart in the textbook that explains it much better

Ronald Thompson 1F

For a final answer I believe you want to use atm unless otherwise stated. You might have to do some conversions (Torr to atm)

Ronald Thompson 1F

Focus on the processes behind the calorimeter example.

Ronald Thompson 1F

If we miss a week can we make it up the next week?

Ronald Thompson 1F

Look at the course website for the update/rundown

Ronald Thompson 1F

Yes, R is the same because it is a constant. It will be given on the constants and equations sheet

Ronald Thompson 1F

Yes, because strong acids dissociate completely

Ronald Thompson 1F

Sig Figs are less of a concern in 14b

Ronald Thompson 1F

We don't pay much attention to liquids and solids in this regard

Ronald Thompson 1F

Test 1 will cover Equilibuium and Acid and Base equilibrium as stated by the announcements

Ronald Thompson 1F

These will be important to memorize, as they do not show up on the constants and equations sheet.

Ronald Thompson 1F

The Process works in both directions depending on the moles of gas on either side.

Ronald Thompson 1F

I believe he just wants the hybridization of the central atom or whatever atoms he asks. However just incase wouldn't hurt to do a couple of practice problems

Ronald Thompson 1F

You can bond multiple atoms.

Ronald Thompson 1F

You would use an elements base name for prefix and suffix of coordination compound.

Ronald Thompson 1F

From what I have seen from two practice exams it is an even breakdown. Most will incorporate many topics into multi-step problems

Ronald Thompson 1F

It is best to be comfortable with both. It will only help

Ronald Thompson 1F

Arrows point to the atom with the negative charge.

Ronald Thompson 1F

Yes, the textbook if for both classes

Ronald Thompson 1F

Formal charge.

Ronald Thompson 1F

I believe for the purposes of this class the spread of the charges doesn't quite matter. I do not recall coming across a problem where the two possibilities have the same formal charge.

Ronald Thompson 1F

Count the total valence electrons and arrange them in a ways that satisfies the elements' octect.

Ronald Thompson 1F

Also try reaching out to past students who have taken the class

Ronald Thompson 1F

I would assume there would be different problems, but if not there's no hurt in the extra practice.

Ronald Thompson 1F

You could look up common bonds and try drawing them out yourself as practice.

Ronald Thompson 1F

Yes, having lower ionization makes it easier for them to gain or lose electrons.

Ronald Thompson 1F

You can also tell by where the atoms are on the periodic table.

Ronald Thompson 1F

Great explanation

Ronald Thompson 1F

10^5? I thought you would just convert from KJ to J?

Ronald Thompson 1F

There's also a list on the 14a quantum world breakdown detailing everything you will need to know how to do for the test.

Ronald Thompson 1F

I believe it is because the spin quantum number has a magnitude of 1/2 in either a positive or negative direction.

Ronald Thompson 1F

On his site I believe he has the sheet with all the equations he will give. To play it safe, if it isn't on the sheet you may want to try and remember it.

Ronald Thompson 1F

In class he used an example where the wavelength was measured at 1.64 x 10^-38m which is unmeasurable,
However an example with a wavelength of 1.4 x 10^-10m was

Ronald Thompson 1F

I believe he was reffering to measurable wavelike properties. If the calculated wavelength could be experimentally seen in a lab.

Ronald Thompson 1F

If done correctly, should I have gotten 5.92?
I also was not entirely sure how to implement Mi x Vi = Mf x Vf

Ronald Thompson 1F

Yes there can be more than one depending on each step of the reaction

Ronald Thompson 1F

Divide by the smallest value, then usually the decimals are close enough to whole numbers that it is best to just round. There are special cases however

Ronald Thompson 1F

Yes that is the way to go. However, if in a problem the molecular formula cannot be reduced then that is also the empirical formula.
