The Periodic Table

There are a number of experimental factors which you haven't detailed. Did your daughter use same amount of pop rocks for volume of liquid? Was the temperature of the liquids the same? What was the experimental error in timing for each liquid? I assume no stirring. But I'm also unsure about the size distribution of the pop rocks. Could an abnormally large pop rock been with the milk? // Off the cuff I'd guess the milk was taken from the fridge and was much colder than the other fluids. — MaxW 22 mins ago

@Kurzd Welcome to Periodic Table chatroom

Kurzd

@Mithoron What do we do here?

Just talk about chem?

Mithoron

01:57

@Kurzd You can read earlier stuff here or in transcript - you can talk about anything unless it's not okay with others. Sometimes chemistry but there's quite a bit of joking and etc

Kurzd

Does this count as joking?
"Should I ping you more <at>Jan?
That's another PPCG thing <at>Jan.
Thought you should know <at>Jan."

My point is, it's a bit...uh...like, inappropriate?

Mithoron

@Kurzd Hahaha xD

Well, this place is useful for users so they can get to know each other better and talk as they like, more freely than in comments under questions or answers.

Although it might sometimes get too free ;)

Kurzd

02:14

I know two SE chats. In both, experienced users use @'s even when the chat is effectively 1-on-1 with me. Is it bad practice not to?

Has anything too bad happened?

Mithoron

@Kurzd Hmm, it shouldn't be used too much, cause this sound can be annoying. Well it's late here, bye!

Pop Rocks

Pop Rocks is a carbonated candy with ingredients including sugar, lactose (milk sugar), corn syrup, and flavoring. It differs from typical hard candy in that it creates a fizzy reaction when it dissolves in one's mouth. == Background and historyEdit == The concept was patented by General Foods research chemist William A. Mitchell in 1957. The candy was first offered to the public in 1975. In 1983, General Foods withdrew the product owing to its lack of success in the marketplace and to its relatively short shelf life. Distribution was initially controlled to ensure freshness; but with its...

Good evening, @Ϻ.Λ.Ʀ.!

I don't understand why we multiply Oxygen's oxidation number by 7 and not by 2 in the equaion used to find Cr's oxidation..

There are two Oxygen atoms in the formula.

@CopperKettle Eh, typo.

Hullo @Duzzy! Welcome to the Table!

CopperKettle

I wonder why O is hybridized in Methanol. It can connect to H and to C without hybridizing, through sigma bonds..

Ϻ.Λ.Ʀ.

@CopperKettle It can?

CopperKettle

@Ϻ.Λ.Ʀ. It has 2 non-paired electrons in p-orbitals, so why not?

It can't, probably, but I'm overlooking why.

Ϻ.Λ.Ʀ.

@CopperKettle Well, I always realized I should first determine geometry, then hybridization; so I can't answer why something may or may not hybridize.

Ron knows lotsa hybridization.

@Mith may also help.

CopperKettle

20:34

@Ϻ.Λ.Ʀ. It must hybridize because there're four "branches" branching off it?

With two of these, lone pairs.

Ϻ.Λ.Ʀ.

@CopperKettle Aha.

But as I told you before, hybridization doesn't really happen.

CopperKettle

Yes, I remembered that!

@CopperKettle Many questions spring up, and that's what I don't like about these dots and lines.

Jan

Nope, still 5-8-5, not upvoting (yet) =C — Jan Jan 18 at 14:12

@CopperKettle It's because oxygen is too small to actually bind two substituents with p-orbitals only.

Mithoron

@Ϻ.Λ.Ʀ. Geometry suggests sort of sp3 - angle more similar to that for sp3, but it's not necessarily true. If unhybridised it should be ~120 - more than there is.

Jan

@Mithoron No, ~90°

Mithoron

@Jan Oh, right.

Jan

The water molecule that is often given as a prime example of VSEPR, is in fact a carefully balanced-out compromise between as short as possible O-H bonds, an s-component of the lone pair as high as possible with the hydrogens spaced out as far as possible. In H2S, there is no real problem, the hydrogens are far enough apart as is and the ideal p-orbital bonding-angle of 90° is assumed.

And nothing changes if you go from water to methanol.

Q: Why does microwaving napalm make it nonflammable?

In this video, microwaving napalm made it nonflammable. What caused this to happen? I assume its some sort of chemical reaction, could someone explain? I understand some chemistry, but a not-too-technical answer would be appreciated.

@Mithoron Microwaving napalm makes it nonflammable 'cause we won't be there anymore to see it burn.

@Ϻ.Λ.Ʀ. XD

duzzy

Let's see... Google... "Hybridization is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties. Hybridization is also an expansion of the valence bond theory." Hmm...

Ϻ.Λ.Ʀ.

@duzzy Also, hybridization doesn't happen in real life, and is purely a mathematical concept.

@Jan Water may be unhybridised - www1.lsbu.ac.uk/water/water_molecule.html

Ϻ.Λ.Ʀ.

Details. Pfft

Jan

@Mithoron What they write is effectively a contradiction in itself.

The increase in bond angle 'due to steric strain' means that oxygen must hybridise to follow the hydrogens' paths.

pentavalentcarbon

@Ϻ.Λ.Ʀ. That doesn't seem very nice.

Ϻ.Λ.Ʀ.

@pentavalentcarbon The fact that meta.chem is boring sometimes?

Or the fact that I was just joking?

@Martin-マーチン, can you add your comment here chemistry.stackexchange.com/questions/43484/… as an actual answer so I can give you credit for it?

@Ϻ.Λ.Ʀ. After all these years I'm still terrible at jokes on the internet, sorry...

Ϻ.Λ.Ʀ.

@pentavalentcarbon I understand how bad it looks out of context.

When you write, people don't know what your intention or intonation was.

So stuff happens sometimes.

Question was just that does it exist in crude oil in this form besides C6H6 — Elmir 9 mins ago

Uh, guys, what are they talking about?

Mithoron

@Ϻ.Λ.Ʀ. This is real nonsense

@Jan Have seen somewhere that lone pairs are perpendicular to each other as if unhybridised

Jan

@Mithoron They are. One is perpendicular to the HOH-plane. The other is in the plane and is parallel to the HOH-angle bisector.

But don't tell me that that points towards non-hybridisation in any way.

Anyone still here btw? @mith? @Ϻ.Λ.Ʀ.? @NotMaitotoxin? @Mart?

Mithoron

21:57

@Jan Then what hybridization would it supposed to be?

Jan

sp(1.7) or so.

One lone pair is definitely a pure p, but the other orbitals are not clear at all.

The second lone pair contains a considerable p-component; it looks closer to p than to sp2.

Serial (Bad) Weddings

Serial (Bad) Weddings (French: Qu'est-ce qu'on a fait au Bon Dieu?) is a French comedy film directed by Philippe de Chauveron released in 2014. == PlotEdit == Claude Verneuil, a Gaullist notary, and his wife Marie, a Catholic bourgeois from Chinon, are parents of four daughters: Isabelle, Odile, Ségolène, and Laure. The three eldest are already married to men, each one of a different religion and a different ethnic origin: Isabelle married Rashid Ben Assem, an Algerian Muslim lawyer, Odile married David Benichou, a Sephardi Jew entrepreneur, and Ségolène married Chao Ling, a Han Chinese banker...
