Whatever happened to this awesome thread? I haven't seen anyone use the quiz topic in about a year.

First:
Haydn spent most of his career working for what Hungarian noble family?

Esterhazy.

What island was Napoleon exiled to? I actually always forget this one, but now I think I remember.

Some Meditteerrraaeeaaann island.
Elba? i think.

Yes, Elba.

How many republic have been seen in France?

fivveeeee

Wrong. It's OVER NINE THOUSANDDDDDDDDDD





okay, maybe it was five.


New Question:
Who ruled first: Louis-Phillipe, or Napoleon III?

Louis?
Its a guess. Blah

Louis is right.
And now since all I can ask about is chem,
What is a pi bond? (is this actually going to be in the curriculum?)

End-on-end overlap of orbitals... I think.

What two conditions make the ideal gases less ideal?

as in when do they form bonds?
Under extreme energy and pressure.

also, this is a pi bond, because I wasn't sure about your answer

Yeah, that's what I meant by the overlap.

For my question I was looking for low temperatures and high pressures. Due to increased interaction between the molecules.

ah, I had forgotten that. It's your question again.

Name an ion Barium can form a precipitate with

Any Halogen?

No.

Aw. Darn my lack of chemistry

I think sulfate would work

Sulfate's good (it's one of the most "famous" precipitates)

none, we're too hardcore for that smurf.

No-one asked a question, so I guess I'll go. What is a resonance structure?

Meh, can't really describe it, but an example would be
X-R=X
X=R-X

Different depictions of a molecule that doesn't have traditional single or double bonds. It's something like benzene, where it has two possible configurations of single and double bonds, but actually has uniform bonds throughout the molecule that don't follow those rules.

That's a better answer than mine, your turn to ask a question

Hmm... yeah, I got nothing, I was just testing myself because I have my Chem AP test coming up. Someone else can take it.

What's the most stable conformation of a cyclohexane? (Name or description will do)

Well, it's a circle (hence cyclo), has six carbons (Hex)
Let,s see, it will have 6 hydrogens, and every other bond in the circle (between carbons) will be double bonds.

(I'm not going to ask questions, but I'm answering these because I have a chem final soon so I'm studying here)

Isn't Benzene a cyclohexane?

No, a cyclohexane is just six carbons in a ring with 2 hydrogens on each carbon. So its formula is C6H12. The trick to the question was that basic cycloalkanes (cyclopropane, cyclobutane, cyclopentane) are simple rings (triangle, square, pentagon, respectively). Cyclohexane is weird because it conforms to a 'chair' formation.

Benzene is definitely not a cyclohexane, because it has 3 double bonds (or 6 intermediate single-double bonds, if you will). Cyclohexane is really just an alkane, so it can't have any double bonds/resonance structures.

Someone else can ask, now.

Okay, just for clarification. Would benzene be a cyclohexene?

How about a French Revolution question?

In 1793, which French king was executed?

Louis XVI

What was a peculiar hobby of Louis XVI?

locksmith, hunting.

no.

Yeah, I was referring to the locks. Hunting wasn't really all that peculiar in eighteenth century France.

BUT YOU KNOW
Moving along.

Which child was Marie-Antoinette in her family? (like, the number i.e. first, second... so on)

She was the 15th, I think. But only 8 or 9 of her older siblings reached hood.

I think?

I don't know exactly how many of her siblings reached adulthood, but yeah she was the fifteenth.

15th?

What are some major characteristics of roccoco art?

What are some major characteristics of roccoco art? (like at least 3)

decorative.Rich people. Cool colors.

also, pastel colors, oil on canvas, ornate out the wazoo. Correct! ask a question!

I'm stealing the question from Vid and asking another chem question (sorry)

"In another universe the physical laws are almost identical to ours except that there are three spin states allowed for electrons rather than two. How many elements constitute the second row of the periodic table in this universe?"
A) 3 B]8 C)12 D)18

(This is on a practice test for my chem final.)

Ummmm B?

No, it's C. The second energy level contains an s orbital and three p orbitals; each one could hold three electrons, so it would take twelve elements to fill them all up.

Thank you, I was wondering what the logic behind the question was. I suppose it's your turn to ask a question.

Which of the following will form a precipitate in water?
A. Lithium hydroxide
B. Magnesium chloride
C. Silver bromide
D. Ammonium carbonate

(Made this one up myself...had to refresh my memory on solubility rules though )

Grr, I never memorized those rules....
I think it's A.... That's mostly a guess though.

*thinks briefly about looking over notes on solubility*

Forget it. It will be bad enough tomorrow when we quiz over molarity/molality. Not hard, but not very enjoyable either.
