the answer key says c-o, but the explanation doesn't sound right. It says that since o is the smallest, but both n and c are smaller, so I really don't know.

Ahmet_Dikyurt_3L

Can someone explain 33b?

Ahmet_Dikyurt_3L

is donating or accepting proton same as donating and accepting h+?

Ahmet_Dikyurt_3L

Di-, tri-, and tetra- should be used for multiple monodentate ligands while bis-, tris-, tetrakis- would be used for for multiple polydentate ligands. What is a monodentate ligand and what's a polydentate ligand? I don't understand the difference. Monodentate ligands have one e- donor to bind with ...

Is this the last week of chemistry community questions, or do we have to ask questions during the finals week(even though our final is on a sunday)?

Ahmet_Dikyurt_3L

How do we get the square pyramidal shape?

Ahmet_Dikyurt_3L

What topics to study for Quiz 3?

Ahmet_Dikyurt_3L

Will the final be on everything we've learned since the beginning of the quarter or everything after midterm?

Ahmet_Dikyurt_3L

The hybridized and unhybridized bonds also help with the shape. Not the shape of the molecule per se but the shape including the electrons (lone pairs and shared)

Ahmet_Dikyurt_3L

Every bond consists of a sigma bond, but double or triple bonds have one sigma and rest pi bonds

This quarter, I didn't take any math class - including LS series - (3A, 30A, 32A), and for Chem 14B, they are requisites that are not enforced but has a warning. Can I still take Chem 14B, even though there is a warning, because I heard some people that you can still enroll in the class without the ...

I was looking through the notes and I wrote that single, double, and triple bonds are considered single regions of electron density in VSEPR model, but what does single regions mean in terms of electron density? I think a single region is just a bond (doesn't matter single, double, or triple bond) ...

Ahmet_Dikyurt_3L

Do double or triple bonds affect the shape or bond angles? I know that they are treated the same electron density, but does the angles change even a little?

Ahmet_Dikyurt_3L

Is it because the electrons are so small (er than atoms), they don't get to be part of the naming? Because I know that only atoms are used in the naming.

Ahmet_Dikyurt_3L

Some molecules or ions cannot be expressed by a single Lewis structure, so we must draw the resonance in order to show the variety and they are all correct.

Ahmet_Dikyurt_3L

The two or three examples given in class also included b and c

Ahmet_Dikyurt_3L

You should do the second half of Chapter 3, the most of first half was done last week

Ahmet_Dikyurt_3L

That is 3.19e but to answer your question, we need to look at Hund's Rule. We need to fill each orbital one by one, so: In d orbital, there are 5 orbitals, so the first 5 electrons go to each orbital, then the remaining 3 goes to the first 3 orbitals. The last two orbitals are left with a single ele...

Ahmet_Dikyurt_3L

What is the maximum number of electrons can an element with a d-orbital hold, since they can hold more than 8
Like Cl, and P

Ahmet_Dikyurt_3L

Heisenberg's Uncertainty Principle was created for very small masses, such as atoms and electrons. For example, in the example he gave us with sensors, the photons thrown changes the direction of an electron, but a photon cannot move you, or a baseball, or a fly.

Here's my work. What I did makes sense to me but I didn't know where to look for the solution so I don't know for sure that it's right. Hope it helps :)1.57Solution.JPG Hi, I couldn't understand how n2 = 7 I also looked it up online, and they also give n2 = 7 I used n2 = 7 in my homework as well bu...

Ahmet_Dikyurt_3L

Can someone explain spin ups and downs? And how they’re represented?

Ahmet_Dikyurt_3L

Is Helium in P-block or S-block? It appears on top of P-block with the noble gases, but has the electron configuration 1s2?

Ahmet_Dikyurt_3L

Wavelengths are lengths, so if there is a direction given, they could have a negative value but distance-wise no. It is the same for every length.
Example: You can say -10 meters east (10 meters west)
Example: You cannot say I walked -10 meters.
Same goes for wavelengths.

I have the 6th edition so all the pages and chapters are based on that.
De Broglie's equation is covered in 1.5 (pages 15-17)
Heisenberg's principle is covered in 1.6 (pages 17-19)
The exercises could be found on pages 25-29

Hello, I was wondering if all of his lectures on the same day are the same? I might have to miss my lecture and is it ok if I go to a different one for that day? If it is, could anyone write the lecture times? Thanks

Ahmet_Dikyurt_3L

Hello, my discussion session is on Friday, and I was wondering if we can turn in questions from Review of Chemical & Physical Principals (the fundamentals chapter), since the questions from The Quantum World are very difficult and there are only 4 questions before we get to the Atomic Spectra Se...

I think larger means higher frequency. Based on what I think, it should be C, but that is just what I think.

Ahmet_Dikyurt_3L

I know that frequency and intensity are different but that's not the question. A wave has a frequency (time needed) and a wavelength, so they are related to each other; The distance between peaks of a wave is its wavelength. Frequency (unit = hertz) is the number of waves that pass in a given time. ...

I know that in the tests, they are given to us, but will periodic tables be provided in the Mid-Term or the Final? Sorry to answer your question with another one.

Ahmet_Dikyurt_3L

I know that the homework is just 7 questions of our choice but I was wondering if we have to answer a question from every topic. For example, this week, there is E, F, G, H, L, and M, so do we have to do one from each or can I turn in all 7 from E.

Ahmet_Dikyurt_3L

Can someone explain how to write the formula of compounds. For example, in question E9 it asks you to write the formula for magnesium sulfate heptahydrate. You need to know the basic formulas. Some names give you clues such as ending with -ate or -ite means there is oxygen in the compound. There are...

Ahmet_Dikyurt_3L

The homework is just seven questions, but I still did most of them on my notebook, then chose the 7 that is correct for sure and write it on a separate sheet of paper. I think that helps me because I go and look over the questions I did, which is a great practice. But you don't need to do all the qu...

Ahmet_Dikyurt_3L

Usually, the question or the previous questions should give you an idea of how much you should round. When I round, I look at the previous questions and if they rounded to the nearest hundredth than I round to the nearest hundredth. If they do it to the thousandth than I do it to the thousandth, and...
