If asked on the final to draw the most stable conformation or the boat conformation, do we have to draw it in 3D with a small shading part?

When solving thermodynamic problems, does constant pressure mean an adiabatic system (q=0)?

What is the difference between tert- and neo-?

When being asked to name a compound, are we going to have to give the IUPAC and common name? Or, is just the IUPAC name okay? (For the final also?)

So for the rate constant of a first order reaction will the slope always turn out negative and then you k is the negative of the slope? What if the slope is positive would you still place a negative in front to get k? Does this only refer to first order reactions?

So what exactly is a mechanism? Is it just the way that you split the reaction into elementary steps?

Is the oxidizing agent the same as the one that is being oxidized? Same for reducing agents?

Will this equation be on quiz number one?

What is residual entropy? How is it different from normal entropy and how do you calculate it?
For example HW 9.75, where did Avogadro's number come from?

It seems like we are almost done with chapter 9 in the course reader, and Lavelle said up to the end of Friday's lecture, which was the start of Gibbs Free Energy, will be on the quiz. So when reading chapter 9 in the book, how much of the reading (sections) on Gibbs free energy will be on the quiz?

Q: Sulfur and Oxygen are best friends, but they lived far from each other. How did oxygen chat with his friend?

A: He used his Sulfone

Hi guys :) so I just wanted to add a link for a phase change graph. I thought it was pretty cool cause it has a few more details and is a bit more clear than the picture in the course reader (or if you do not have the course reader). So, here's the link: http://mrzimmerman.org/New%20Folder/HW/phases...

In the solutions manual, it says that the initial concentrations of HSO4- and H3O+ are 0.15 mol. How do we know that it was fully dissociated to the H3O+ rather than the other compound?

Corresponding to what Phu Mai 4G said, it can also be disregarded if x is less than 5% of the initial value.

The phrase ion is used at the end when you are naming an ion complex which like Rachel said is when the complex has a negative or positive charge. When it is just a coordination compound (neutral charge), you do not say ion after you write out the name.

Within the coordination sphere, you write the transition metal first. Afterwards, you write the anionic ligands followed by neutral ligands.

This is a question from Chapter 11 homework page 457 problem 11.37B. So it originally gives you the equation N2 + 3H2 -> 2NH3 and a K that is equal to 41 In part B, it asks you to find K for (1/2)N2 + (3/2)H2 -> NH3 I noticed that each coefficient had decreased by half, but the solution manual says ...

What is the difference between a formation constant and an equilibrium constant? Or are they the same thing? The textbook and course reader each use a different one.

When I am predicting the type of hybrid orbital for lets say H3O+, can I just say sp^3? Or do I have to say 2sp^3 because O is in the second period of the period table?

I know when you draw a resonance arrow between two structures it is just a double headed arrow, but how do you draw them if there are three structures? Is there a special way like almost forming a triangle between the three structures? Or, can you just draw them all side by side in no order?

So I know that H, Li,and Be are exceptions to the octet rule but is He also? The first lecture we began discussing lewis structures I remember Lavelle saying "H, He, Li,and Be," but the course reader only says three? Then two lectures later, he said it again... so yea? is He considered an ...

Okay, so I understood how to do the problem it was just once I reached the answer I got a different answer. I was not off by much but enough to get the answer wrong. It was just somewhere my sig figs messed up and resulted in the wrong number. After calculating the E=hv, I got 1.02 x 10^-9. I guess ...

In problems that give you the work function value, how am I able to tell whether there is an amount for kinetic energy or not (0)?

I believe the wave model demonstrated that light had only contained wave properties. Therefore, it did not involve the idea of quanta. The photoelectric effect, like Neil said, proved that light has wave and particle properties. It showed that if light had only wave properties, then electrons should...
