Hey M.A.R I know u but u don't know me...OK let's keep it secret

Ok tell me if Na can reduce KCl

Anybody may be

M.A.R.

@Assassinsunity oh crap, an assassin knows me

Assassins unity

Ya ,I have eyes on everybody

Can Na reduce KCl ,if Yes then why? Contradiction K comes below Na,so K is more electropositive than Na

@gannex can you answer above question

M.A.R.

@Assassinsunity it's not just about electronegativities

Which is higher in the electrochemical series?

Assassins unity

09:23

@M.A.R. the reduction potential of Na is less negative than K

M.A.R.

@Assassinsunity then you have your answer. Under standard conditions, the reduction can't happen

Q: Transition state optimisation on the surface of periclase

I want to model a reaction catalysed by periclase ($\ce{MgO}$) using DFT. I have a good guess on the transition state (TS) of the reaction that goes in gas phase/solvent (produced using MOPAC). The proposal for this reaction goes by the Eley–Rideal mechanism and I have a good guess on how the re...

Q: Is there a term for a procedure in which the chromatography column is washed with 20% alcohol

From a method description in a Russian document: After the chromatographic analysis is complete, the column is flushed with at least 2-3 volumes of water at a rate of 0.4 ml/min. The column is then mothballed (?) by washing it with at least 10-15 volumes of 20% alcohol at a rate slowly declin...

It was originally posted by @CowperKettle on Bio.SE, where I answered it.

Q: The Amazing Migration of an English terminology question to Russian Language Stack Exchange

I've just discovered that my question asking about an English term that an English biotechnitian would use was migrated to, of all possible SEs, the Russian Language SE. This is just to register my amazement at this decision. I've very little free time right now. Let me cite a comment left by...

Maybe it was not a good question. So just kill it then or block it. Why migrate to RUSSIAN SE? O_O

Okay.. busy

Jan

Considering joining Biology just to upvote that meta post …

hBy2Py

I think it was a perfectly fine question. On the border between Bio.SE and Chem.SE.

ELU is probably the most ideal place, but I guess they don't have enough scientists over there and thus get cranky with science questions.

Loong

@hBy2Py Apparently, the migration to Russian Language was rejected. The question is now back on Biology.

hBy2Py

Ahhhhh. Didn't even think to look back on Bio.SE.

hi...

That's why I hate migrating...

Jan

Apparantly, migration on Biology is a community decision? There were five names in the post history …?

Martin - マーチン

only do it if it helps, some people just think out of sight out of mind

Loong

@Jan If multiple users vote to close as off-topic with different reasons, only one reason is shown when the question is finally closed.

Jan

13:57

@Loong Post migrated away to russian.stackexchange.com by AliceD, David, another 'Homo sapien', kmm, WYSIWYG♦.

Martin - マーチン

@Jan It shows all names that put a CV vote on it.

Loong

Yes, all close voters appear in that list, although only WYSIWYG has voted "off topic, belongs to Siberia Stackexchange".

Jan

That probably makes the most sense … Although it does make it look like five people said ~~banish to Siberia~~ give this post a one way ticket to an interesting and novel destination.

Martin - マーチン

I don't think biology has migration paths, especially not to russian

Loong

@Jan We have a similar problem when some users vote to close as "homework" and then others vote to close as "unclear". The result looks like all users voted to close as "unclear".

Jan

14:06

Unless the majority voted homework/generic off-topic, in which case the unclear votes are subsumed.

But that’s ‘okay’ since it’s just different close reasons. Migration was planted in a different area of my brain, no direct connection …

Martin - マーチン

well... in order to migrate a closed post, you have to reopen it first. The mechanics are meh.

Jan

I would star that post for ‘The mechanics are meh.’ xD

Sir Cumference

Quick question, why is fire usually associated with plasma?

M.A.R.

@SirCumference Because people feel it's easier to explain by relating it to plasma

Sir Cumference

@M.A.R. Uh, how?

They're two different things

M.A.R.

The reason something is usually a popular pop culture explanation is it's the stupidest explanation scientifically

Sir Cumference

That's true...but I don't follow the logic

M.A.R.

20:20

The logic is that there's no logic

Sir Cumference

Wait what

How does that work

Loong

@SirCumference Is it?

Sir Cumference

@Loong Well, yeah, that's why most people think the Sun is a ball of fire

M.A.R.

Try explaining to someone that believes they only got their blue eyes from their blue-eyed mom that both parents had a role in it

Sir Cumference

@M.A.R. Well at least it's half true to say they got their blue eyes from their mom.

I can't find anything relating fire to plasma

M.A.R.

20:25

@SirCumference "Ahh, I remember from school that matter can only be solid, liquid and gas. So what's fire? It's not a normal gas, and not liquid or solid either. Wow, there's this thing only scientists know about called plasma, and I don't know what it is. Fire must be it."

Loong

@SirCumference I can see why people think the Sun is a ball of fire. But that does not necessarily lead to the conclusion that fire is a plasma.

M.A.R.

I remember one of the top Google hits searching for ''is fire . . .'' was ''is fire alive''

There's no limit to how stupid people can be

Sir Cumference

@Loong Well, first we get questions like this

21

Q: Why there is no smoke around the Sun?

Where there is fire, there is always smoke. So why there isn't any smoke near the Sun?

sun

Here it is

...the hell?

M.A.R.

As much as the education school offers is crappy, it solidifies the concepts it aims to well.

@SirCumference Add http

Sir Cumference

Ugh, wrong link

M.A.R.

20:27

Love its title

Sir Cumference

@M.A.R. Read the abstract

Loong

@M.A.R. Fire is alive. It can undergo metabolism (breath and consume food), can grow, adapt to its environment, respond to stimuli, and reproduce. ;-)

M.A.R.

I guess it's really a pain in the A for astronomers to deal with pseudoscience

Chemists are one of the luckiest in that regard

Sir Cumference

^

M.A.R.

@Loong That was too philosophical for me to handle. I might crash in the next moment

Loong

20:29

sorry

Sir Cumference

@M.A.R. Chemists might be safe from pseudoscience, but astronomers will go out of their way to annoy chemists

Like this image

M.A.R.

@SirCumference You can try

@SirCumference Well, neon can prolly be a metal if you push it hard enough

Sir Cumference

@M.A.R. Astronomers call any element above helium a metal

M.A.R.

Carbon has already a hard time deciding whether to be a metal or not

Sir Cumference

That's why "metallicity" refers to the abundance of elements heavier than helium in a star

M.A.R.

20:31

Well, it doesn't annoy me. I have seen more annoying things right in my school, coming out of the mouths of friends and non-friends alike

Loong

@SirCumference Astronomers really work with elements up to Cn?

Sir Cumference

Then again, astronomers usually call plasmas "gases". They rarely differentiate them.

M.A.R.

SO NICE TRY, MWAHHA

Sir Cumference

@M.A.R. I feel like this would be solved if high schools just explained what a darn plasma is

Loong

@SirCumference That's ok.

M.A.R.

20:33

@Loong Up to Og

Sir Cumference

@Loong Only up to 94, theoretically :P

Artificial ones aren't relevant

Loong

@M.A.R. I don't think the r-process can make Og.

Sir Cumference

^

M.A.R.

Oh, can it make Cn?

I thought we were aiming for the highest Z element possible.

Sir Cumference

@M.A.R. Huh? No, that doesn't appear in nature

M.A.R.

20:35

@SirCumference Well, what do astroers have to do with Cn then?

Sir Cumference

IIRC the highest element to appear in nature is 94, plutonium. Any higher are artificial, any lower are natural as well.

@M.A.R. Nothing, he was joking :P

M.A.R.

WELL WHY DO YOU have to ruin MY joke? !!flip

Chemobot

ʕ ⊃･ ◡ ･ ʔ⊃︵┻━┻

Sir Cumference

But in seriousness, I feel like so many problems would be solved if high schools taught plasmas

Loong

I was talking about Cn because it's the last element in the above-mentioned picture.

Sir Cumference

20:37

@Loong Jeez, you recognize where Cn is?

M.A.R.

@SirCumference I don't think any problems would be solved

Sir Cumference

@M.A.R. Some of my friends argued that fire could exist underwater because it's a plasma

M.A.R.

The current global problem is lack of scientific and critical thinking, not lack of knowledge per se

Sir Cumference

I don't even know what that's supposed to mean

@Loong Here's a better (though not entirely accurate) pic

hBy2Py

@SirCumference Because it's not.

Sir Cumference

20:38

@hBy2Py I know, that's the point I'm making

I'm still wondering why plasma is usually associated with fire, and vice versa

hBy2Py

@SirCumference Probably because they both emit a lot of light (at least, in popular conceptions), and most other matter doesn't.

Sir Cumference

@hBy2Py Uh, most matter doesn't radiate visible light or...?

hBy2Py

@SirCumference If you get it hot enough, yes.

But the filament of a light bulb is neither fire, nor plasma.

Sir Cumference

Yeah, I was confused why you said "most matter doesn't emit light"

Loong

@SirCumference Yes. And if they don't simply say that plasma is another state of matter like solid, liquid, and gas.

hBy2Py

20:41

But at the level of knowledge that most people associate fire and plasma, there isn't knowledge that hot matter almost always emits light.

Sir Cumference

@hBy2Py But they're only related by one thing. They both emit light.

hBy2Py

@SirCumference I'm not trying to say it's a good connection to be making. :-)

It's just an easy, if fallacious, connection to draw.

M.A.R.

@SirCumference Which is usually enough

Your amazement amazes me

Sir Cumference

@Loong Oh come on, I've had no problems teaching to third graders what a plasma is

hBy2Py

@SirCumference But you understand it.

M.A.R.

20:42

The masses don't know and don't want to know what siencez looks like

hBy2Py

Probably some of the people trying to explain it, don't.

Sir Cumference

@M.A.R. That's...surprisingly true

hBy2Py

And fire/plasma is the best thing they can come up with.

Sir Cumference

Most people think the Big Bang was an explosion in the middle of space that created everything

M.A.R.

They only need to be skeptical about frigging scientists working for all the evil corporations and governments

Sir Cumference

20:43

@hBy2Py But...but...they're so loosely connected

M.A.R.

Especially after Dawn of the planet of the ~~Apes~~ orange-haired squirrels

hBy2Py

@SirCumference Dude, read up on the history of chemistry

M.A.R.

And I love that movie

Sir Cumference

@M.A.R. I have heard people say that they don't trust any scientists or government

hBy2Py

You will be amazed at some of the theories people argued strenuously in favor of.

Sir Cumference

20:44

@hBy2Py But, how does that relate to fire being plasma?

M.A.R.

@SirCumference Yeah, global warming is a myth to get some funding for poor homeless scientists

Sir Cumference

@M.A.R. And all science is a myth created by big governments

Loong

@hBy2Py so … phlogiston is a plasma? ;-)

hBy2Py

@M.A.R. Relationships between things/phenomena were frequently drawn on pure observational evidence -- often because that's the only data they had.

Sir Cumference

@Loong So is aether (in the physical/astronomical sense)

M.A.R.

20:45

@Loong No no, only when it's reacting with air

Sir Cumference

Didn't realize aether was a legit thing in chemistry

hBy2Py

@Loong Hehe - phlogiston is electron holes.

Or... is that right? Hm.

Sir Cumference

So wait, where were we?

Oh yeah, pop science misconceptions

hBy2Py

When you don't have a grasp of the necessary underlying theories/models, whether due to incomplete education or to the simple fact that they haven't been figured out yet, you try to make sense of things, and make connections between things, based on what evidence you have.

M.A.R.

@SirCumference Your font tells me you get nervous a lot

Sir Cumference

20:48

M.A.R.

And wake up, sheeple. Vaccines cause autism.

hBy2Py

If you asked a fire-plasmagon what the state of matter of a light bulb filament is, they might seriously consider for a time that it might be plasma.

M.A.R.

@SirCumference Wow, they managed to disprove all science

Sir Cumference

@M.A.R. They followed with this

M.A.R.

-1 not long enough

Sir Cumference

20:50

@hBy2Py You don't need to know the underlying theories or models to remember that fire is a chemical reaction, and plasma is a state of matter

Just knowing that is good enough

M.A.R.

It's so hard to find good trolls these days.

Every idiot has access to teh interwebz

Sir Cumference

@M.A.R. That's why we get questions like this too

And honest question, can anyone tell me whether this is nonsense or not?

I'm 99% certain it is
