I am looking to measure something with .1mg/.0001g accuracy. Anyone have any idea where I could go to temporarily use a scale like this? The scales on amazon are rather expensive. Please ping me thanks!

Paying would be okay

@Hexacoordinate-C well almost

@hBy2Py the conspiracy runs deep

@GaurangTandon yes, you're alive!

let's see what all happened here this fortnight

Q: How to determine the angle between non-bonding electron pairs?

Is there a way to determine the angle between non-bonding electron pairs that aren't obvious? Take $\ce{H2S}$ for example: The two non-bonding electron pairs would be at the yellow end of this molecule, but I am curious as to what the angle is between them? Is there even a way to tell?

oh oh that meta post...

Honestly though, as long as the message is correct and actionable, I don't care whether the person is a meta.SE troll, or a relatively new user of Chem.SE. I think I agree with penta here, the only major flaw in that meta post is that it is too vague to be actionable. There aren't just enough stats at the moment to prove if we actually get a lot of off topic unsalvageable questions or if we are actually more strict than necessary.

A better way to put the message across would have been as in Recent close statistics - with a clear message and some definite questions.

though the lack of definite statistics really troubles my mind. @M.A.R.ಠ_ಠ it's definitely not a "molehill". the fact that more than half of the questions that our site gets actually don't belong to our site should indeed be cause for concern

honestly, I find Martin's answer really vague. "Hence I also think there are plenty a many unwarranted closures or at least ambiguous ones. ... I think some more leniency would benefit us." is sort of what peterh was also suggesting

@peterh If you're really concerned and really think that there's something wrong with having such a high close rate then stick around for a month or two go edit stuff, make yourself seen, be a part of the community. Then voice your concerns because right now you're just somebody who ran some numbers and saw that chem SE has the highest closed/deleted ratio and thinks that it is not okay. Nobody likes to sit around and closevote for the sake of it. — Avnish Kabaj 9 mins ago

This isn't rude or anything right?

@AvnishKabaj I don't think there was any point in engaging with the OP any further

@pentavalentcarbon thanks for your reply on that repo. just went through it, and you've raised some really interesting points. I would probably take some time to write a proper response to that, and reconsider my stance on what I was proposing

> Nobody likes to sit around and closevote for the sake of it.

I think they do...

Gaurang Tandon

^^^ reviewing close votes often makes me feel: "why would people want to close this question as X?", and the lack of any comments definitely makes it feel like that...

pentavalentcarbon

Time to check the queues...

Gaurang Tandon

Are there some problems? — thoraz 24 secs ago

yeah, actually too many...

pentavalentcarbon

loads

I don't remember what I wrote, I'll have to reread it

ok...I feel like I could have gotten to the point quicker, but I remember now

Oh @GaurangTandon You are back, how is it going?

I have to convert cyclopentanol's -OH to -D (deuterium).
I have this method:
Alcohol + HBr to install Bromine in place of -OH and then reduction using $\ce{LiAlD4}$, how feasible is this process?

@Abcd I would suggest PBr3, then make a Grignard and quench with D2O

M.A.R. ಠ_ಠ

20:56

@AvnishKabaj it's certainly not rude, but it might be anything. Hmm, maybe it's anything

@GaurangTandon If you wanna feed the troll, be my guest

I'd rather have the discussion with someone who has actually good intentions

orthocresol

I raised this point several months ago. However, people seem to not think it’s a problem.

M.A.R. ಠ_ಠ

@GaurangTandon I didn't say the issue he brought is a molehill. Anything you say, whether you disagree with him or not, here's gonna reply with "your site is suffocating". How will that result in constructive discussion, I dunno

@orthocresol too much crap?

orthocresol

Yes, there are lots of bad questions of late. Most of them seem to be of the homework variety. At some point it may stabilize and people will ask good questions. One can hope. — Jon Custer Nov 13 '17 at 20:20

i.e., “let’s wait for the situation to improve without doing anything”.

M.A.R. ಠ_ಠ

Hmm, I think that's because the fix requires some inspired and persistent effort

orthocresol

But as I said in a comment, it’s really two problems in one.

M.A.R. ಠ_ಠ

21:02

Ya know, TRE-like investment

orthocresol

First is that the average question that comes in is not great. Second is that we close stuff that doesn’t really need to be closed.

Yeah, I agree. It’s not a quick fix.

M.A.R. ಠ_ಠ

We didn't have the investment then, but we might now with the new guys

Unfortunately, I won't be able to invest much until after transplant

Which is in almost a month and half if things go as planned

Would somebody help me with the following paragraph? ' The pressure of air at your mouth would be about 1 atm (...) The pressure of water trying to squeeze the air out of you is about 1.3 atm [10-foot down the water]. Your diaphragm is not strong enough to overcome the squeezing and fill your lungs with air. ' Why does he says it would not be possible to inhalate?'

user280247

It's an extract from this post: chemistry.stackexchange.com/questions/61406/…

user280247

I think I don't understand it, cause it argues we cant inhalate when pressure is 1.3 atm, being that the diving has a oxygen supply at 1.4 atm, so, for me, It will be possible to inhalate.
