What is the coordination compound and transition metal for Hemoglobin?

leilawilliams16

How do you determine the number of electrons for a transition metal in a coordination compound Lewis structure?

leilawilliams16

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

leilawilliams16

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

leilawilliams16

Is this the same as Reidberg's constant?

leilawilliams16

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)

leilawilliams16

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

leilawilliams16

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."

leilawilliams16

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?

leilawilliams16

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.

leilawilliams16

So should we always calculate formal charge before drawing the diagram or is this semi-unique?

leilawilliams16

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

leilawilliams16

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

leilawilliams16

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

leilawilliams16

can someone provide an example of how this principle is applied in an actual problem? I understand the concept but I haven't really understood how it translates to a real situation

leilawilliams16

when does h represent Planck's constant and when does it represent frequency? how do I differentiate

leilawilliams16

what exactly is the relationship between quantized energy and the n energy levels? I am a little confused

leilawilliams16

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)???

leilawilliams16

My high school chem teacher did not stress this!!!! please explain SOS

leilawilliams16

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