1. ### General Solutions to a Linear System

According to this, http://upload.wikimedia.org/math/5/8/2/582b41cd88284564c46e711cbbca55fa.png http://en.wikipedia.org/wiki/System_of_linear_equations#Homogeneous_systems A general solution to some linear system is a particular solution (P) + a homogeneous solution (H) My question: is...
2. ### SP Carbon Orbitals

It seems like they are both sp2 to to me :O
3. ### Valid Resonance Structure?

So my 2nd structure isn't valid because that would mean the carbon would have 5 bonds? (another carbon, the double and 2 hydrogens) ? If that's right it seems the hydrogen is still there?
4. ### Valid Resonance Structure?

So why is the 2nd step of my resonance structure invalid, then?
5. ### Valid Resonance Structure?

So even though we remove a H, for purposes of bonds we pretend it is still there? Is what I said above correct? Thanks
6. ### SP Carbon Orbitals

When the hydrogens/protons are removed, leaving C-, can someone please tell me what and why the SP orbitals of these two carbons are? http://img30.imageshack.us/img30/5333/40529044.jpg [Broken] Thanks.
7. ### Valid Resonance Structure?

Thanks. My question was because of this: I was wondering if you made the C have a negative formal charge, if that was the same thing as pulling off a hydrogen/proton. But I guess the negative charge is because of another electron around the atom, not the loss of a hydrogen, which would mean...
8. ### Valid Resonance Structure?

I know it doesn't show all the places, I'm asking if that is ONE of them. I don't think it is, since wouldn't that mean the carbon would have 5 bonds? (another carbon, the double and 2 hydrogens) ?
9. ### Valid Resonance Structure?

It's a way of showing more than one lewis structure where they are sort of moving in and out of each
10. ### What's the sp orbital of this carbon?

Domains = things the atom is bonded to where "things" are: single pairs, lone pairs, double bonds Is that what you meant? So the carbon is sp2 right?
11. ### What's the sp orbital of this carbon?

Never learned that
12. ### Valid Resonance Structure?

Not to be rude, but I would love it if you could answer my question even briefly. I know what resonance is, I can assure you of that. :)
13. ### Valid Resonance Structure?

is mine just not valid because it violates the octet rule since there are H's involved as well?
14. ### What's the sp orbital of this carbon?

It is possible, it's from my book. Since it has a double bond, it's sp2 i think? I just don't know if the - formal charge affects that.
15. ### What's the sp orbital of this carbon?

Meant to upload this one, sorry. is it sp2? sp3?... http://img198.imageshack.us/img198/5062/92513846.jpg [Broken]
