Q: Why do comments cost 50 reputation, but answers don't cost anything

Seems to me like this is broken: If I don't have an answer, I shouldn't be posting one, but that is the only way to ask a question or get clarification. Also, why should I be able to answer anything if I have no reputation? What good is my word?

Holy shit I never knew! I'm just gonna put bounties instead of comments from now on

@hBy2Py honestly, I don't know what to say...

i can only thank you for your kind words...

@GaurangTandon so you did say something for his kind words

I don't think there's a good enough body gesture for a thank you

Oh man, Dave's got a point though

Changing 2 to 2 and 4 to 4 is hellishly nitpickish

I imagine @Gau found out he can edit posts, then he went crazy with the red, googly eyes spinning and a frantic laugh

HEEERE'S EDITORRR!!!

@GaurangTandon @AvnishKabaj Are we supposed to learn pH ranges for all indicators?

I wouldn't wanna be in Gau's shoes right now

Act in good faith . . . Do exactly like trusted users and mods say . . . End up being yelled at. Well, not yelled at, but been grumpiered through

Yay, I invented English

Avnish Kabaj

@M.A.R. What happened is Dave still grumpy?

M.A.R.

I wouldn't wanna be yelled at.

. . . WHY THE HELL DID YOU DO 1250 EDITS IN COUPLE OF WEEKS?

@AvnishKabaj nah, I am being rudely awakened

Realizing I wouldn't wanna be in his shoes. They're tiny, baby shoes

Avnish Kabaj

@M.A.R. I wonder what a grumpy M.A.R looks like

M.A.R.

Also, I hate an inactive chat. Had to spew something

@AvnishKabaj GET OFF MY LAWN

Avnish Kabaj

@M.A.R. shizzzz this is your chat

@M.A.R. ha, I was just collecting interesting many posts to read and learn new stuff; I edited them simultaneously as I read them; look at the humongous favorites list I generated - chemistry.stackexchange.com/users/5026/… that's not to count the many chrome bookmarks I have, phew...

i think this break will give me the necessary time to cleanup my bookmarked stuff

@M.A.R. I did not have a better way to say that, and it's almost exactly what I feel...

Can someone please help me enable chem jax?

I have asked it three/ four times here

Whenever I type $\ce{}$ in chat, it is displayed in red

Gaurang Tandon

@Abcd idk

Abcd

(I am using the website, not the mobile app)

M.A.R.

16:39

@Abcd you have loaded MathJax without mhchem

Abcd

@M.A.R. So how do I get mhchem

Gaurang Tandon

@M.A.R. so, \require{mhchem}?

M.A.R.

@Abcd make a bookmark of Mart's code in the answer to how to enable MathJax meta post

Drag it every time you wanna turn it on

@GaurangTandon that didn't seem to work last time I tried

Which was two years ago, I think

Gaurang Tandon

M.A.R.

Oooh, this one instead actually

A: How can I enable MathJax in chat?

Update 2017-05-01 The MathJax CDN retired and the javascript-URL idea is not so easy any more, because of browser security. (Chrome stips away any leading javascript: when pasting into the URL line. SE modified the javascript: link so that it does not work.) So here is my take. I modified the ...

$\ce{chemjax <=> enabled}$

M.A.R.

Stappit it's annoying

Abcd

not enabled yet..

M.A.R.

I cussed quite a number of times before getting it right.

It didn't break after that, though

My laptop broke sooner

Abcd

$\ce{Hi -> Bye}$

Woah! Done!

[pings organic chemists] do you guys use this site anymore? organic-chemistry.org

i mean, the letter requesting donations is more than five years old

organic-chemistry.org/info/letter.htm

that means the founder either should've got the amount of money he requested (and remove the letter) or have abandoned the site due to lack of money

this site turns up in every single google search i make, and it's UI is like that of 2008

very very disturbing

M.A.R.

16:54

Ha, it uses that bright red color . . . Pink! Right.

Gaurang Tandon

no offence, but that site almost feels like a 13yo kid just beginning to learn CSS styling

for those coloring reasons, exactly

M.A.R.

@GaurangTandon maybe he discovered the perfect unbreakable polymer, earned billions and now lives on the International Space Station.

Gaurang Tandon

i meant styling, not content, the latter I think is probably awesome, but I don't know

@M.A.R. hehe, who knows :P

M.A.R.

I've read content from there before

I can't remember whether it was good though

Which means it wasn't too bad.

My autocorrect loves wad and hates was.

Gaurang Tandon

@M.A.R. hold on the word, it should give you an option to delete the prediction (assuming swiftkey)

Q: which atom's better at forming coordination?

in [Fe(CO)5] both C and O can form the coordination bond with Fe but why Carbon atom forming the bond instead of Oxygen arom which has lone paired electrons?

coordination-compounds

I tend to think of @ortho as a foretelling parrot.

Alright @Secret, I read your explanation in the transcript and understood most of it. I saw the dissociation constants here

Now, as far as Option iii) and iv) are considered, I'd like to ask you if we can use Fajan's rules? $\ce{Ca(CN)_2}$ has more covalent character than $\ce{KCN}$, so it would dissociate less in aqueous medium.

Hence, the final order we get is:

$(ii)<(i)<(v)<(iv)<(iii) \space{} (\text{option 2})$

Can you suggest what you've tried so far and why it didn't solve your problem? — ericksonla 6 mins ago

It has a warm and fuzzy feeling to seeing someone you don't even know remind an asker about the homework policy

Like Logan watching Laura slash some throats

So cute

BTW, Logan is an awesome movie. Go watch it.

A: Correlation between 1H and 13C shifts - coincidence or not?

Apart from other specific effects, chemical shift is a function of electron density around the nucleus, so it is reasonable that proton shits roughly correlate with those of the attached carbon.
