@Martin-マーチン however "zu recht" would be translated ... xD

9:03 AM

@pH13 actually... dunno

to law

I also had to think twice, with what reason I am going to close it

@Martin-マーチン Close it as "unclear what you're asking" because we don't know enough chemistry to know what HHO is.

We expect more avid askers like you to tag responsibly, form an appropriate title, format the post well and type the question since images aren't searchable. Please don't let us down. — inɒzɘmɒЯ.A.M 12 mins ago

i closed it as opinion based, mainly because the existence of hho is an opinion

"Urgent exam question" so that's the reason behind the LQ posts that user posts these days.

@inɒzɘmɒЯ.A.M ??? -> (╯°□°）╯︵ ┻━┻

@Martin-マーチン At least I didn't call that dump dump.

Who's the other one you're throwing?

whoever is here to be thrown ;)

that would be me :P

@ph1 isn't it great, that for a three-parameter functional you have to specify six parameters.... 3, 2, 1, mind blown O.o

@skillpatrol sorry about that then

┬─┬ ノ( ^_^ノ)

np pal

:-)

@Martin-マーチン in the b3 part there are only 3, HF, Slater and Exlocal

the lyp brings the other two

and the sixth parameter is the stupid 1 or 0 ^^

btw, have you guys used the new "highlights" option at the top of the chat page yet?

High . . . lights?

what?

Q: Custom-defined functionals in Gaussian 09

9:16 AM

1

As stated before I want to try out custom-defined functionals. Besides the question about B3LYP itself, there is another related question. Short excerpt: $$\text{XC-Functional}=a E_x^\text{local}+(1-a)E_x^\text{HF}+b E_x^\text{non-local}+c E_c^\text{non-local}+(1-c) E_c^\text{local}$$ T...

computational-chemistry software

@pH13 looking at your mmmmmnnnmnmnmnmnnnnmnmnmnmnmnmnmnnnnnmmmmmmnnnmmmmmm is an eye sore.

I think I figured out how the program selects the "highlights." It uses a combination of starred messages and if there are no starred messages then it uses the specific user requesting for highlights @ messages to highlight.

@inɒzɘmɒЯ.A.M please write gaussian that there input is ugly

@pH13 gaussian that there input is ugly

whatever I code for others has a beautiful and easy to use input

@pH13 Thanks for the laughs.

@bon I respectfully disagree.

No it's not it's a matter of personal interest. I just thought of this and thought it looked interesting — billmann 1 min ago

Maybe it's not HW, but huh?

9:44 AM

@inɒzɘmɒЯ.A.M *sigh*

@Martin-マーチン Why?

o/ @inɒzɘmɒЯ.A.M

this is one of the cases where you could read a book about it

Him, not me. ಠ_ಠ

is it hw?

mayhaps

9:45 AM

@pH13 @pH1: rightly so ;)

Unless you mean I should've read a book about pro forma comments.

@Jan He. Is. Not. Acidic. Stop calling him that.

it's at least such a question where you are like... ohhh too lazy to think about it

I'm not alone @inɒzɘmɒЯ.A.M ;p

@Jan He's a mod, thus he's allowed to call people anything he wants, even if it changes their chemical properties.

remember, calling me acidic makes me sour

9:47 AM

@ph1+12 does that ping?

It does.

@Martin-マーチン indeed

@pH10 doesn't though?

pH 0/0 is undefined

:-)

@skillpatrol Nothing is undefined in pH.

It's just that "Henderson-Hasslebalch fails".

9:51 AM

are you saying 0 is undefined in pH?

Yes, but -3 isn't.

pH(1/0) =?

@pH13 whooo

@Martin-マーチン are you a whoooooo- ~~girl~~ boy?

10:07 AM

Whooooooooooooooo's a whooooooo-boy? D=

whoooo-hoooo-hooooo

well... i gotta go now... another birthday tonight, see y'all

@Martin-マーチン have fun

later pal

@mith it would have been more helpful had you edited the title to read nitrite rather than nitrate (III). It took me a good minute to understand what you meant and that OP’s question actually was valid. — Jan 21 secs ago

12:18 PM

The concentration of the solvent is $55.5~\mathrm{M}$ approximately, I can tell you that. — Jan 21 secs ago

Dawww, he edited the question =C

Loong

@Jan was someone confusing solute with solvent?

@Loong Yeah xD

ok

A: Why does aluminum have a lower first ionization energy than magnesium?

4:26 PM

what do you guys think about this answer

4

The easiest way to explain it is that $\ce{Al}$ has one unpaired electron in it's highest energy orbital ($\mathrm{3p}$), and $\ce{Mg}$'s highest energy orbital ($\mathrm{3s}$) the electrons are paired. It is energetically favorable for all the electrons in an orbital to be paired, which means th...

Looks correct to me …

goes against everything I know... (which is not much, but still)

stabilisation is derived from electrons with parallel spins in different orbitals... if it was so favourable for everything to be paired, then there would be no high-spin transition metal complexes

4:45 PM

Maybe it's not well put ...

For aluminium, the highest-energy electron is in an otherwise unoccupied orbital, so the energy to remove it is rather low. Only one p orbital occupied is a degenerate state and thus unfavourable. (Compare with oxygen's ionisation energy which is less than nitrogens; 1 paired electron in the p orbitals i.e. degenerate again.)

On the other hand, neon, helium and magnesium have rather high ionisation energies because they have completely filled orbitals. The state of being completely filled should be more favourable than being completely filled but one electron.

Which is also the reason why $\ce{K3[Fe(CN)6]}$ is a good oxidising agent: $\ce{K4[Fe(CN)6]}$ has all the orbitals of one energy level completely filled.

@ortho, in case you didn't see it.

thanks for the explanation @Jan

Makes somewhat more sense this way.

Also part of the explanation of Jahn-Teller, btway.

yeah

I remember that haha

Distortion of the octahedron by lengthening the z-axis means that discrete energy levels are either filled or half-filled.

Guyses I might or might not be able to be in chem in the next two days. Just saying.

Day of Ashura

The Day of Ashura (Arabic: عاشوراء‎ ʻĀshūrā’ , colloquially: /ʕa(ː)ˈʃuːra/; Urdu: عاشورا‎; Persian: عاشورا‎‎ /ʕɒːʃuːˈɾɒ/; Turkish: Aşure Günü) is on the tenth day of Muharram in the Islamic calendar and marks the climax of the Remembrance of Muharram. Shiite celebrations of the Day of Ashura have traditionally included rituals which have been condemned by many religious authorities recently under the claim that such practices are wrong or unislamic. This day is commemorated by Sunni Muslims (who refer to it as The Day of Atonement) as the day on which the Israelites were freed from the Pharaoh...

BTW @Mith @anyone else don't believe what you see about Ashura rituals on the Net. It's just means to destroy the image of shiite rituals and the beliefs behind it. :(

8:19 PM

@inɒzɘmɒЯ.A.M Stuffs on the net shouldn't be believed anyway. See HHO.

@inɒzɘmɒЯ.A.M Does that mean, you're not here for TRE tomorrow? D=

@Jan Yeah, most probably.

Another reason for the world to end D=

Number one was me making a green salad as part of my dinner tonight D=

@Mart leading TRE tomorrow lies on your German, responsible hands.

@Jan Number two is @Mart leading TRE tomorrow.

@inɒzɘmɒЯ.A.M @Mart will bring us all sausages and TRE will be a sausage party! \o/

@Mith @Jan @Ortho @Wytha @Bon @Wild and @anyone else who will participate in tomorrow's TRE please heed @Mart or who he points out to be the leader in tomorrow's TRE. I will at best be able to watch from afar what you guyses are doing.

And @Mart, I think it's time for Episode 2 - Tag Focus. i.e. focus on one/two/three tags in each TRE and polish them by ridding them from where they shouldn't be and applying them where they should be. @Mart I'd recommend getting rid of the workload on esters and smell.

8:31 PM

Do we have no broad single tags left? I would have thought inorganic-chemistry or physical-chemistry would have been the next prime targets …

@Jan Tomorrow's TRE may well be a continue to Episode 1. "Reaction-mechanism", "everyday-chem", "inorganic-chem" and many other tags could be nice next targets.

Ah, good ^^ Me no likes serious changes =3

However, I see a more urgent need in heeding esters, carbohydrates, smell and some other new ones. \cc @Mart

But if you all want, you can continue with Episode 1. Look, I'm not the boss in the next TRE, do as you wish. :)

Just don't waste time sitting on and thinking what you should do. That 90 minutes is precious.

But procrastination is one of my special skills D=

Not here. ಠ_ಠ

Mithoron

Pfft, my whole activity here may be considered procrastination

@Mithoron Pssshht, people might find out that the same is true for me =O

Anders MB

I should study for an exam. Why am I on Chemistry SE??

@AndersMB At least you can argue that that is a reason (assuming a chemistry exam) ;)
