I always use "I Bring Clay For Our New House" to remember the naturally occuring homonuclear diatomic molecules, that takes you up and over forming the 7 shape that K9-47G was mentioning

And generally the term "diatomic molecule" is ambiguous, it could mean either two identical atoms or two different atoms.

I was cleaning some glassware in the lab today with methanol and got some on my hands. I had just put fresh nail polish on that morning and after the exposure to the methanol, there was a white film all over my nails. It comes off with a bit of scratching but I was just wondering if any of you knew what was causing this.

Have any of you had a professor that told you, and the entire class, on several occasions "This will not be on your exam" only to make at least a quarter of the final exam exactly on what he told you he would not put on it?

I had that happen to me this morning for my organic chemistry exam, and I just wanted to know if this prof's just a jerk, or if this stuff happens more often than I think.

I actually haven't heard of that textbook, sorry hornet!

I am currently using Carey for my orgo class, and hate that book. The prof is constantly correcting it, and its in a very illogical order! I've heard people say some decent things about Hornback's textbook... you can always look into that. All I know for sure is to stay away from Carey, its a trainwreck.

For pchem, I enjoy Silbey, Alberty et al's Physical Chemistry book. Its a little dry, but its good.

1. Age? 19

2. Gender? Female

3. Where do you live? New Brunswick, Canada

4. Natural Hair Colour? Brown with some red in the summer

5. Natural Eye Colour? Brown

6. Do you dye your hair(what color)? Or what do you want your hair color to be?(you don't have to pick a different color)

I have dyed it before (golden brown). I would like my hair to be a darker, chestnut colour brown

7. Do you have colored contacts? Or what color would you prefer your eyes to be?(you don't have to pick a different color)

Just clear contacts, and I like the brown

8. Heritage? Not too sure, but there's some French, and some Brittish, and a little German

We're using Stewart 5ed, it's a pretty good book, lots of example questions

But they can't test their grandfather, so they can't assume he was bloodtype I(A)i. If Coral Rehdd's aunts aren't related by blood then his/her grandfather may not be I(A)i.

I know, all I said was that its possible.

Actually, its quite possible...

Its a case of multiple alleles (you can find this in any 1st year Biology textbook). It works pretty much the same as dominant/resessive genes, except there are a few more possibilites. You have I(A), I(B), and i. If you have type A blood, you could either be I(A)I(A) or I(A)i, same for type B. If you're type AB, then you have I(A)I(B), and if you're an O, you have ii

Now, in order for you to have aunts that are type O and type A blood, and for your mother to have type B blood, your grandmother must have had I(B)i, and your grandfather I(A)i. Now if you work out the punnet square, you get 4 different possibilities, I(A)I(B), I(A)i, I(B)i, or ii; type AB, A, B, or O.

So assuming your grandfather was I(A)i, then your family's blood types work out just fine (as any blood type is possible for your grandparents' children), and your aunt likely wasn't adopted. Hope this helps!

They offer a free online physics textbook, its a pretty good site so definitely check it out!

I was doing my thermo chem assignment, and I got completely stuck on this question, can anyone help please?

"Calculate the second virial coefficient of methane at 300K and 400K from its Van der Waals constants given that a(CH4) = 2.283 L²·bar/mol² and b(CH4) = 0.04278 L/mol."

I've always heard it pronounced de broig-lee (g as in go), and I'm pretty sure its you-ler

This one's better and more catchy

Cellular Modular Interactive-odular

Wow, that sounds incredible.. however I'm in the same boat as the other two, no money

(a) change of mass over change in time, (dx/dt) = ax (where a is the constant)

Now all you have to do is solve that DE and part (b) should work itself out
