Question from final [ENDORSED]
For question 3 (I believe?) on the final, what would classic particles like dust do when sent through the slits?

SO2
Is the lewis structure for SO2 most stable with one or two double bonds? Different sources say different things

Re: R in PV=nRT [ENDORSED]
Is this the same as Reidberg's constant?

Re: convertine to partial pressure
The conversion equation is PV=nRT, where P=pressure (atm), V=volume(L), n=number moles, R= Reidberg's gas constant, and T= temperature(Kelvin)

Re: VSEPR and Electrons
In relation to the previous reply, since molecular geometry only considers the bonds, do you still indicate electron repulsion and modified bond angle? This confused me

4.45
Can someone walk me through question 4.45?
"Describe the structure of the formaldehyde molecule, CH2O, in terms of hybrid orbitals, bond angles, and sigma and pi bonds. The C atom is the central atom to which the other 3 atoms are attached."

Stability/ Midterm [ENDORSED]
If the Lewis structure I found for the compounds on the midterm had all formal charges equal to zero, was that the most stable? Is the structure with formal charges equal to zero the most stable in all cases, including radicals?

Midterm
What were the correct answers for the bond identifications (ionic, non polar, polar) on the midterm? I believe one molecule was KCl and another was N2 but I forget the third.

Re: Only certain central atoms have a full octet?
So should we always calculate formal charge before drawing the diagram or is this semi-unique?

3D shape Lewis Diagrams
When we are asked to draw a Lewis diagram, do we need to know how to draw the shaded, 3D version as well?

Would we be asked something like that, where the molecule we are given has an octet exception, on a test?

What exactly will test 3 cover? Which equations are the most relevant? There are some in the book we have ignored in class, thanks!

wait so if every element has a unique spectroscopy then how do our problems all coincide with the same spectrums/ do we need to memorize the spectrum lines (Laymen series etc)???

so you won't get marked down for interchanging them on the tests?
