The Periodic Table

Well, my theory is that you only really learn through reading. Since you're the one controlling the reading's pace, but they're the one controlling the video's.

DHMO

do you stress on "ir" or "rep" in "irrep"?

@Rubisco my theory is that books cost money

user116211

You should try Herstein Topics in Algebra; it acts as a good introduction to abstract algebra @DHMO.

DHMO

@MAFIA36790 sure

Is there an infinite number of generalized point groups?

By generalized point groups I mean that C2v C3v C4v ... count as one

orthocresol

@Rubisco Amen to that, I hate watching videos.

So I was watching a video about the ionic product of water on YouTube and in the comments section, I saw this:

user228700

user228700

But in my textbook, they have included water too, to calculate $K_w$! Look:

Wildcat

11:20 AM

@DHMO It is possible that a molecule have a 7-fold rotational axis.

DHMO

@Wildcat cycloheptane?

I dont think it is

user228700

Oh, crap, no, they haven't. And OK, @JR said before that the activity of water is 1 so alright, OK, never mind me. Sorry :P

DHMO

@Wildcat maybe we need (c7h7)+

Wildcat

@DHMO maybe something awkward like this :D

cause I could not come up with a real-world example

DHMO

@Wildcat what about c7v? i thought c7h7+ is real

Wildcat

11:25 AM

@DHMO It might be real, but I'm not sure about its geometry anyway.

And what's the point?

I mean, nature is almost entirely asymmetric.

DHMO

sure

Wildcat

So, yeah there some simple small molecule which are highly symmetric.

But that is all to it.

And besides, nuclei are in constant motion.

And besides, the whole notion of a molecular geometry is an approximation.

DHMO

sure

molecules are stretching all the time

Wildcat

So, I don't quite understand why do you even bother with SALC?

Do you need it for a job?

DHMO

to construct LCAO?

no

user228700

11:28 AM

Actually, no. In the context of that picture that I uploaded, can anyone please quickly tell me the difference b/w writing $H_2O$ (l) and $H_2O$ (aq)..?

Wildcat

If not, ignore it.

@DHMO you don't need to symmetry adapt LCAO

DHMO

@Wildcat thats such a good news to me

then how?

Wildcat

You can just completely ignore the symmetry of a molecule.

Unless you absolutely need it.

DHMO

@Wildcat then how do i find the coefficients?

Wildcat

@DHMO you don't, programs do.

Rubisco

11:30 AM

I need molecular symmetry for my grandchildren

DHMO

@Wildcat how do programs do it?

Wildcat

@DHMO they solve special equations

DHMO

such as?

Wildcat

All in all, different LCAO results in different energies of a molecule.

Programs find one particular combination that results in the minimum energy.

Well, that's not the whole story. :D

DHMO

user228700

No? OK :-(

orthocresol

@DHMO The tropylium ion is D7h.

Wildcat

(aq) simply means that the corresponding substance is dissolved in water, i.e. is a part of an aqueous solutin

orthocresol

@KaumudiHarikumar that picture is OK at simplistic level, but really, it should use activities, not concentrations.

trying to rationalise something at the simplistic level, only leads to more problems.

DHMO

@orthocresol thanks

orthocresol

11:47 AM

@Wildcat was a good summary, ;)

DHMO

> To make the harder things simple, first you need to make the simple things harder.

Now, can someone come up with 15 resonance structure of H2?

orthocresol

@KaumudiHarikumar Anyway, whether you write (l) or (aq) does not affect the ionic product. The water does not care what you call it - it only cares that its activity is 1, or pretty darn close to 1.

It's not possible that the way I, or you, write the equation, can change what's going on in the system. So, those post hoc justifications in the comments are off-track.

The idea is that, $$K_w = \frac{a_{\ce{H+}}\cdot a_{\ce{OH-}}}{a_{\ce{H2O}}}$$

Rubisco

Well, that's what I thought

orthocresol

But $a_{\ce{H2O}} = 1$, so you drop it from the equation, and therefore this simplifies to

Rubisco

But I thought maybe it's a creepy foreign high school thing

orthocresol

11:53 AM

$$K_w = a_{\ce{H+}}a_{\ce{OH-}}$$

and because the activity, numerically, is approximated by the concentration, at a lower level, this is often simplified to $K_w = [\ce{H+}][\ce{OH-}]$.

(Yes, Loong, I was lazy to type \mathrm{w}.)

Would the 1s orbital of He be different from that of H?

Orbitals in He are not derived by solving SE for He.'

Their existence is an assumption.

Then they solve meta.SE

Russell's paradox

In the foundations of mathematics, Russell's paradox (also known as Russell's antinomy), discovered by Bertrand Russell in 1901, showed that some attempted formalizations of the naive set theory created by Georg Cantor led to a contradiction. The same paradox had been discovered a year before by Ernst Zermelo but he did not publish the idea, which remained known only to Hilbert, Husserl, and other members of the University of Göttingen. According to naive set theory, any definable collection is a set. Let R be the set of all sets that are not members of themselves. If R is not a member of itself...

Spherical cow

A spherical cow is a humorous metaphor for highly simplified scientific models of complex real life phenomena. The implication is that theoretical physicists will often reduce a problem to the simplest form they can imagine in order to make calculations more feasible, even though such simplification may hinder the model's application to reality. The concept is so commonly known that it is sometimes referred to in scientific discourse without the need for further explanation. == Details == The phrase comes from a joke that spoofs the simplifying assumptions that are sometimes used in theoretical...

user116211

That's why the weak version of Schema of Comprehension i.e., Axiom of Separation is followed:

> If $P$ is a property, then for any $X,$ there exists a set $Y= \{x\in X: P(x)\}\,.$

See, the set is pre-defined, as is done in the form of $X$ here.
