How are hydrogen atoms and hydronium ions the same?

Soyoung Park 1H

The size of the atoms/ molecules have to be taken into consideration as well, not just the forces.

Soyoung Park 1H

Yes you would multiply 6 by Avogadro's number so it would be 6 mol C x (6x6.022x10^23atoms/mol) which comes out to be 2.17x10^25 atoms.

Do we have to memorize all the 7 strong acids for the coming up final?

Soyoung Park 1H

Can someone explain what ligands are?

Soyoung Park 1H

Tetrahedral has 4 areas of electron density while square planar has 3, and they both have 0 lone pairs.

The greater the overlap, the higher probability the valence e- in between the nuclei which means stronger and shorter bonds.

Soyoung Park 1H

Adding onto that, you can study bond angles and the shape names:)

Soyoung Park 1H

Does hybridization relate to AX2 and AX3? What do these mean??

Soyoung Park 1H

Is the test over both outlines 3 and 4?

Soyoung Park 1H

What's the difference between bent and angular molecular shapes?

Soyoung Park 1H

Are we going to have problems where we have to calculate the strengths of bonds?

Soyoung Park 1H

So what is exactly VSEPR model?

Soyoung Park 1H

What does it mean to be a highly distorted e-?

Soyoung Park 1H

Do you always check for formal charges even for single bonds?

Soyoung Park 1H

How do you know what center atom is for the lewis structure?

Soyoung Park 1H

When do you use brackets around the lewis structures?

Soyoung Park 1H

As bonds increase, does energy increase? Also, are shared pairs stronger than lone pairs?

Soyoung Park 1H

What does having lowest energy e- configuration mean exactly?

Soyoung Park 1H

Does anyone know where to start drawing dots? For Chlorine for example, all sides have two dots except for the left one. I'm not sure of the order.

Soyoung Park 1H

The pictures that Professor Lavelle had on the presentation on Friday about d orbitals had cones and planes surrounding the orbitals while pictures in google images don't include them. What do they mean?

Soyoung Park 1H

When do you know to use the De Brogile equation? Will the questions always contain the words "De Brogile wavelength?"

Soyoung Park 1H

Will we only get questions related to Atomic Spectra and energy levels about the H-atom? Also what is the difference between the Ballmer series and Lyman series besides the region differences?

Soyoung Park 1H

What does a photon of energy mean?

Soyoung Park 1H

Do we have to memorize numbers such as c=3.00x10^8 m/s and planck's constant (h=6.63x10^-34Js) for the test?

Soyoung Park 1H

When do you use photoelectric effect equation? The equation says (E=hv)-(work function)=Ex. What does Ex mean and stand for?

Soyoung Park 1H

I was working on that problem too and I got wondering about the same thing! Can anyone help us out?

Soyoung Park 1H

Are the posts due on Saturday or Sunday of every week?

Soyoung Park 1H

Thank you so much! After reading your post, I am not as worried as before about the class!
