4:59 AM

@PH13 Yeah.

5:50 AM

So tempted to answer with "yes" chemistry.stackexchange.com/questions/35001/…

inɒzɘmɒЯ.A.M

@chipbuster I don't even know if they really know what an isomer is.

the questioner confuses me

inɒzɘmɒЯ.A.M

It's like saying C6H12 turned to C6H12. Is it a chemical or physical change?

sometimes asks some quite decent questions

sometimes they're a total mess

inɒzɘmɒЯ.A.M

Correction: They're a total mess, unless proven otherwise.

Q: Why Can't Carbon Have Tetrabonds?

Carbon has 4 valence electrons, so it means that it can have a total of four (covalent) bonds, right? (Tell me if I'm wrong) IF that's the case why can't Carbon share four bonds, such as with another Carbon atom? $\text{C}_2$ I have recently learned of the Uncertainty Principle, and the orientat...

Just look at how much fluff I edited outta that.

AND, they're Indian, which makes matters worse.

5:55 AM

ah yes

and it always bugs me when people BOLD ITALICIZE CAPS THAT THIS IS NOT A DUPLICATE

yelling something doesn't make it true

inɒzɘmɒЯ.A.M

GOOD THING THEY DON'T KNOW THEY CAN MAKE USE OF UNICODE CHARS, LIKE THIS: ლ(ಠ益ಠლ)

Q: Formation of esters. Which way is better?

Esters can be formed by 02 ways,( there can be more than 02 ways,but according to the syllabus I'm studying,it is just 02) Mixing alcohol with carboxylic acid in the presence of sulfuric acid Mixing alcohol with acid chloride. My question is which method is better to form an ester?I mean which...

organic-chemistry esters

ESTERS CAN BE FORMED BY 02 WAYS, not 2 ways.

I...have never seen that before

o.0'

I mean, I have, in auto-formatted texts

but never when a human is writing like that

oh, high school student

inɒzɘmɒЯ.A.M

Must be. We're taught to be robots.

6:04 AM

robots eh?

I was taught to be a zombie

I wonder if there are any ninja/pirate schools of chemistry out there

Q: Should we not use MathJax in Tag Wiki excerpts?

While going though the new tags, I spotted, that the esters was created, which eventually brought me back to the endeavour of tagging functional groups in general. (Should we create tags for common functional groups?) While I was editing a couple of questions, to include nitro-compounds, I noti...

12:14 PM

Can someone help me with my chemistry project? I have to write about "the acidity of fruits and vegetables" but I am not getting any idea about what to write in the introduction

write everything first and as the last thing, write the introduction

and never, ever start with "Once upon a time..."

would be funny

it was, but my supervisor was not amused

@PH13 thanks, ok I will write the intro after everything. What should I write after the intro section?

12:20 PM

@Kartik I don't know ... make an approximate list of contents, arrange them logically and then try to write your text :)

but at first, write what you think is important. don't think too much about every sentence, write it. after that you can always change things and rearrange things.

@Kartik make a table like this (in German)

@PH13 Can you just tell me the name of the sections ... I will be able to write the text myself.

@Kartik how should I know how your sections are named?

@Loong Thanks for the table. But actually I am finding problems in finding content for the text

@PH13 I have not yet started the project. I am just asking you to suggest some sections

@Loong you will soon get an Enlightened badge and you're welcome ;)

12:23 PM

ask google, ask wikipedia and find stuff that is related to the acidity fruit and vegetable

then think of what could be interesting or important to know about it

@Kartik that is part of your work - you need to decide what sections would be relevant - research first and then work out the sections

I will not do this for you, as no one else would probably do that here

@PH13 I have already done that but google doesnt give me anything related to chemistry

search harder

Ok then I will try to do it.

12:25 PM

@Kartik my google tells me another story

@PH13 What did you search for?

my google tells me another story too, probably has been conferring with PH13's google

lmgtfy.com/?q=acidity+of+fruits+and+vegetables

lol

@santiago Thank you! That explains why I suddenly feel so enlightened. :-)

12:26 PM

@Loong great answer!

anyway good people, I must go to bed and dream of weird and wondrous things

@santiago That is just copy/paste from the Blue Book.

@Loong but it is a good copy/paste!

@santiago vampires and badges?

@Loong yes, and badges wearing vampires....oh wait...

homework vampires

12:30 PM

@santiago asked 100 homework questions without getting any answer

@Loong lol and me taunting with comments

anyways, I am going to bed

@santiago good night

12:46 PM

@Kartik maybe this is a little helpful

@PH13 Thanks a lot.

I have found out some sites and started writing the content.

sounds good

@PH13 Right now this is my table of contents: 1. Intro 2. Definition of acid (Arrhenius and Bronsted) 3. Various methods for checking for the presence of acids (Taste, ph paper, etc.) 4. Types of acids present in fruits 5. Types of acids in vegetables 6. Comparision of acidity of fruits vs vegetables 7. Uses and dangers of these acids 8. Closure

Is it fine?

sounds good

what do you think should the 7. Uses and dangers of these acids section be about?

@PH13 Like what kind of diseases these may cause and how they are useful like salicylic acid can be used to make medicines but some other acid may be harmful

12:59 PM

in which fruits or vegetables do you find salicylic acid? I think that sth like oxalic acid is a better point

@PH13 Ok, I will search for that also

1:15 PM

Hi!

hi

For fruits citric and ascorbic acids are rather more important ;)

when you get kidney stones, think again of oxalic acid

1:30 PM

do me a favor and tell me if the symbol for Angstrom renders on your respective browsers - see chemistry.stackexchange.com/questions/35014/…

and hello @PH13, @Kartik, @Mithoron

@ToddMinehardt Hi

hi @Kartik, how's it going?

hi @ToddMinehardt

hey @PH13

user image

1:32 PM

excellent

@ToddMinehardt unicode is a nice workaround

don't get, why there is no \AA

@ToddMinehardt Its looking fine but the circle is a little small

(On chrome)

@PH13 i know, that drives me nuts

@Kartik - ok, better than nothing

FYI, it's $\unicode{xC5}$ to get that character

I saw it after clicking on edit :D

alternatively, you can go with x212B

cool

or $\overset{\circ}{\rm A}$, but that will render depending on a person's locale, so i think the unicode way is probably best for a worldwide audience

1:36 PM

@ToddMinehardt they are slightly different :D

@ToddMinehardt I think that the unicode one will vary more

@PH13 - yeah, i know. be nice if \AA worked...

@ToddMinehardt I'd love to have that ...

it's an open issue with MathJax, apparently - that's where i got the unicode solution

@Kartik - is the unicode glyph dependent on your locale? i suppose it is...

@ToddMinehardt What is locale?

1:40 PM

more or less what your browser settings say your default languages/fonts are

so it might not be UTF-8, and could be Cyrillic, or something like that

you can set how your browser gets stuff from the server that sends the page to you -

obviously, depending on your native language/alphabet/etc., this will vary

for me, it's en, en-gb (english, then english-great britain). for @PH13, it might be de, en-gb (german, english-great britain). and so on.

@ToddMinehardt might be ... where do I find this? ^^

depends on your browser - but see this w3.org/International/questions/qa-lang-priorities.en.php

should be [de]

typically buried in the settings somewhere

right, [de]

i use Chrome, and use UTF-8 under the Encoding tab

(that said, that's a character set encoding and not locale)

@PH13 on Chrome, in Settings, it's under Language and Input Settings

@ToddMinehardt I think I found it and it is [de]:)

1:52 PM

cool

2:23 PM

By the way, I am aware that the ångström is still widely used by crystallographers; however, I would prefer to use proper SI units. The use of the ångström as the spectroscopic unit of length was abandoned by the BIPM in 1960.

2:34 PM

@Loong I think not only by crystallographers but also by the comp chem community

@ToddMinehardt don't hide

@PH13 That’s understandable, since chemical bond lengths lie in the range of a few ångströms.

@Loong it's also always good to be backward compatible

user image

@PH13 Sure, don’t get me wrong: Certainly, you should be able to understand and to work with ‘ångström’.

2:54 PM

present :)

hi @Loong

i see there's a unit discussion

@ToddMinehardt would you mind help me with python stuff?

@ToddMinehardt hi

the fafoom thing? or other?

@ToddMinehardt yes, I want to add another wrapper to use it with orca

(sure @PH13 if i can)

2:56 PM

I will open a chatroom for this

@inɒzɘmɒЯ.A.M the one in the background

@ToddMinehardt My biggest remorse is that \rule doesn't work. :(((

so forget "suspiciously similar", this question is a blatant copy-pasta

inɒzɘmɒЯ.A.M

@PH13 I thought you were the beautiful ~~girl~~ base that the protagonist is gonna win.

@inɒzɘmɒЯ.A.M only in your dreams

oh, and congratz on yearling, @inɒzɘmɒЯ.A.M

5:39 PM

@ToddMinehardt Hah! Are you on mobile?

@inɒzɘmɒЯ.A.M which app do you use for chatting here?

inɒzɘmɒЯ.A.M

@PH13 Chrome

AKA I hardly chat on mobile.

@inɒzɘmɒЯ.A.M ok ... I searched for an app in the app store

inɒzɘmɒЯ.A.M

@PH13 Support the devs and install it!

@inɒzɘmɒЯ.A.M I've done that ^^ but I was wondering if you might have found a better one

inɒzɘmɒЯ.A.M

5:49 PM

Better than the official app is the full site.

the SE-app does not support chat, afaik

I use ChatSEy

inɒzɘmɒЯ.A.M

Who's that?

that the app

for the chat

inɒzɘmɒЯ.A.M

WHATEVER.

I hate anything SE on mobile.

^^

better than nothing

I'm Enlightened! :D

inɒzɘmɒЯ.A.M

5:56 PM

Oh?

Congrats!

But I'm double-enlightened. ᕙ(⇀‸↼‶)ᕗ

:O u sooooo strong

@inɒzɘmɒЯ.A.M - i'm on a regular browser (workstation) not mobile

chrome

inɒzɘmɒЯ.A.M

So why didn't you edit your message?

easier to take the low road :)

inɒzɘmɒЯ.A.M

Yes @Todd.

Hover over a chat message, a down-arrow appears.

Click it.

6:04 PM

@inɒzɘmɒЯ.A.M - thanks!

inɒzɘmɒЯ.A.M

No problem.

SE stuff is really confusing, because other than very basic functions of the site, there are no FAQs.

yes, it's a pretty steep learning curve in that regard

inɒzɘmɒЯ.A.M

So when you're a more established user than a passer-by, it's either that you ask someone how to do something, or you just have no idea about it.

6:25 PM

@ToddMinehardt Yep, UT :D

inɒzɘmɒЯ.A.M

@Todd you need to freak out now.

hey cool - i was there from 1991-1999 (and still live here/work here)

any idea who you'll work for?

ha @inɒzɘmɒЯ.A.M

I'm actually in the computer science department

hopefully doing comp bio work

statistical methods on proteins

ah, ok - nice. great program there...

hope it'll be fun

inɒzɘmɒЯ.A.M

6:29 PM

It's always proteins. Famous last words

well, "fun"

i got into proteins after grad school - seemed fun to me

i imagine the field has progressed greatly since i've been in it

7:29 PM

@bon Your tag wiki only describes carboxylate esters. I think esters includes more than that.

inɒzɘmɒЯ.A.M

And look at me, having that tab open for two hours, and procrastinating making a wiki.

lol

inɒzɘmɒЯ.A.M

\o

@Loong Does it? I think there may need to be a meta discussion about this. I hadn't considered other types of esters

8:08 PM

hmmm almost at 4k

@bon Don't get me wrong; I clicked "approve".

@Loong Someone can always improve it to add other types of esters. I'm gonna make a meta post to sort out the scope of the tag

8:20 PM

@bon Maybe we can borrow something from goldbook.iupac.org/E02219.html

inɒzɘmɒЯ.A.M

@santiago If we were a beta, I would've said damn you!, but since we're not in beta, congrats!

lol

@bon But first we need another user with 5000 rep to accept your work.

inɒzɘmɒЯ.A.M

@bon Sigh if only more users joined chat.

Maybe it's cursed.

Q: Scope of esters tag

Since esters has now been created I set about writing a tag wiki for it. I have only included carboxylate esters in the scope of the tag but @Loong pointed out that there are other types of esters (orthoesters as well as many inorganic ones - phosphate, chromate to name a few) as well.

Also what happened to your big meta post I heard about

@bon OK. Good point. I was looking for clear cases of "esters questions" – not just questions that mention the word "ester" somewhere.

So there goes your poll @Bon. Now everyone (aka @PH13 @Loong @Bon @Todd @San @Nicolau) in chat, please vote up the poll that you see fit.

@inɒzɘmɒЯ.A.M I didn't notice about that nitroglycerin question. Technically it isn't a nitro compound so it shouldn't have the tag but we're getting into messy territory now
