The Periodic Table

I don't understand the use of the word "ions". The manganese is not in the free ionic form, isn't it?

It's part of MnO4.

@CowperKettle It says manganate, not manganese.

@IͶΔ I see. Thank you!

@pH13 - you deleted your question on the mathematica SE, but I had already worked out how to do it. Maybe you did as well, but here is the code I came up with: pastebin.com/raw/VWdpx6eG

1:01 PM

@JasonB Thank you very much. I deleted the question as I found further information that made me think if my question is based on a wrong assumption and I didn't want to make someone think about a problem that might not exist.

@user36790 hihi, unfortunately I've got to go off already

Anyway, the purpose of this chat room is to annoy @IͶΔ so..

@IͶΔ O.O

A: What *is* a 'homework question'?

4:22 PM

After being awfully quiet about this for a long time, I think it's time to give this another push. What is a 'homework question'? I don't know. And I don't want to know. I really think it is the wrong question to ask. The term itself comes with the perception that it is an assignment, see Wikip...

Dang it man. This is the moderator attitude I love.

@IͶΔ: I hate HW questions that seek like check my work, how to do this; have no idea

Q: What should be done with "Is my calculation correct ?"-type questions?

Is my calculation correct type-questions.

I see many questions where the OP just asks whether his or her calculation is correct . These type of questions will most likely not be helpful to the majority . The questions pertain to a specific numerical calculation or to a specific application of a formula which the OP thinks might be wrong ...

Q: Should any check-my-work questions be made on topic?

It's long overdue that I make this post revisiting our policy on "check-my-work" questions. These are questions, often (but not necessarily) homework-like, that present a complete mathematical or logical derivation and ask whether it's correct. Historically our homework policy has rendered check...

Q: Why don't we just ban homework altogether?

This site gets a lot of low-quality homework questions. Since I ignored the homework tag a few months ago, my experience of the site has been much more pleasant. The current homework policy is nice, but the questions that actually obey it are few. I think this is because if you've put the effort...

discussion homework

Kicks @User2 for bringing something from meta.physics

user116211

@IͶΔ relevance o.O

Physics is a different concept and moderating a site about physics is different.

I don't think we should be that aggressively exclusionist unless we have to in a far far future.

user116211

@IͶΔ If you go to math SE, then you'd be amazed at how many HW questions come but they aren't frowned at.

4:36 PM

Not really

@user36790 Math.SE is a trashcan, I know. :)

user116211

HW should be asking about specific concepts like how it happened; the book asks this; but why should it happen like that; that would be quite good question.

user116211

In a word, they shouldn't be localised

@user36790 Sometimes.

@user36790 They removed the "too localized" CV reason a while ago from SO since it was being abused.

Its loss is prevalent though.

user116211

@IͶΔ oh, didn't know that.

And everyone from back then missed it.

@pH13 I upvoted that comment just for you.

7:05 PM

great

I appreciate that

@IͶΔ did you read his question?

7:37 PM

@pH13 Nope

I just saw it.

Well, an 100k'er SO user sure knows how to post properly.

@IͶΔ it's about the idea itself ^^

It's way smarter than some ideas I've seen in Sci-fi. Ask @Mith

Q: Does human sex matter when dealing with chemical products?

Not exactly sure where this question fits. But, it is common to see products like shaving cream, razor blades, hair removal products, vitamins - all of which are marketed in 2 major categories, for men and for women. From a chemistry standpoint (as I assume any difference will be firmly found i...

@CowperKettle trashcan

Being a gentleman, I would not name the place where it fits.

There could be some vitamins more suitable for pregnant women.

But razor blades..

I never knew copper can be so gentle.

8:15 PM

that might probably fit to healthcare, no?

Since I'm Cowper for a while. (0:

also lotions and cremes, etc, are different for men and women ... so I think this might not fit to chem.se but it's not a bad question

@pH13 Dunno.

I don't think we have a womenvsmen.SE.
