This should be a (hopefully) simple style sheet change. Meta is already doing it, and other sites are also. The effect is generally subtle and I approve of subtle: $\color{magenta}{\text{I fully support subtle variations of hot pink}}$.

This doesn't look right. $\mathrm{|{}^1H|}$ $\mathrm{|{}^1H|}$ and $\mathrm{|\ce{^1H}|}$ $\mathrm{|\ce{^1H}|}$ should give the same result. They don't. $\mathrm{|{}^1H|}$ $\mathrm{|\ce{^1H}|}$ I'll debug this further. Please don't use workarounds like \! because things will look weird after an update. (Hmm, StackExchange hasn't updated MathJax for 3 years.) ...

As a workaround, you could use $\ce{$0.5$\,H2O}$ to get $\ce{$0.5$\,H2O}$

It's not a bug. I don't know how the system determines what suggestions to show there, but it is completely different for me (logged in/out, different devices). It almost seems to be random. [...] it's been deprecated for a long time [...] Let's not forget, the homework tag is deprecated as a result of our meta discussions. The system itself doesn't ...

Loong hit this earlier than me. status-by-design Sometimes when you put the computer to sleep, or are on mobile, or do whatever else so you pass the client based restriction of not being able to add the answer after the question was closed, you can still post your answer for as long as 4 hours after the question being closed, because the server still ...

The documentation you linked is for mhchem v 4.01 (dated 23 April 2015). It is likely that Chemistry.SE uses an older version of the package that renders charge differently. Also note that Chemistry.SE uses the MathJax filter to process math mode $\LaTeX$ (including mhchem) and the problem could be in MathJax. For example, MathJax converts $\ce{SO4^2-}$ into ...

Or you can use $\ce{1/2\,H2O}$ to get $\ce{1/2\,H2O}$.

This bug was caused by /sites route in the stackexchange api not returning MHChemMathJax in markdown_extensions due to configuration changes for the mhchem 3.0 upgrade. The fix is already rolled out, so the apps should be rendering mhchem after a restart. However, the apps are using embedded mathjax & mhchem .js files. We'll need to update the apps in ...

Based on your questions you seem to have a misconception as to the purpose of closing a question. Please read What does it mean if a question is "closed"? first, then come back to this. Why would I close my own question? I imagine this is a rare scenario, but it is sometimes used, e.g. when the asker finds a duplicate of their own question after ...

This issue has been solved since mid of 2016. $\ce{0.5H2O}$ renders as $\ce{0.5H2O}$. Short background: MathJax is NOT LaTeX. MathJax is a complete re-implementation of LaTeX using the same input syntax. Almost the same, with fine differences. The same applied to mhchem. The behavior of LaTeX/mhchem (written by me) was re-created for MathJax (by the ...

This was indeed confusing. I have tweaked it a bit and that's how it looks now, hopefully it's more clear:

Yep! This is because we haven't made the entire site responsive yet. It's not a bug so much as still on our to-do list. It's part of why we've asked Help us improve the user profile and settings on Meta Stack Exchange. We're going to have to revamp the user profiles to make them work in responsive design, but we also want to know what you all feel would be ...

Thanks! Some of the things are already fixed on my harddrive (the "undefined" error), but not published yet. The others, I take as valid input for my todo list. For now, 10^-10 can be written as e-10, but I'll support explicit exponents. What does $8.001 \pm 0.005~\mathrm{nm}$ mean? Shouldn't it rather read $(8.001 \pm 0.005)~\mathrm{nm}$? I am not sure if ...

Unfortunately the app uses a different version than the website. That does include the recent updates to mhchem, especially the \pu{...} command. While \dfrac can and should be avoided in general, that is not really true for the mhchem updates, as we would lose all the recent development discussed on meta. We'll have to see and wait how the developers ...

thanks for reporting. This is indeed because of black top bar becoming taller. Fix is waiting in repo for next build, so you should be able to see it in next couple hours.

MathJax/mhchem 3.0.6 should fix the issues. It supports all standard uncertaincy notations as listed at https://chemistry.stackexchange.com/a/58667/24052. It will take a week or so to make its way to here. You can test this not-yet-released version at the bottom of https://mhchem.github.io/MathJax-mhchem/

I think I can shed some light in here. Note that my timeline for this question is a bit more extensive. First the question was closed. Then the OP edited the question a few hours later which caused it to enter the reopen review queue. This review was completed with "leave closed". After that the question gained a reopen vote, which again caused it to enter ...

The question is unanswered in the sense of stack exchange: it does not have an answer with a score higher than zero. You can see that the answer by oscar has a score of -1, so it does not count. (The deletion probably came later than the newsletter was sent, we would have to know the time when it was composed to compare, so it still shows up there.)

I think this is intended, it's just slightly bad wording. What it says is: This is a favourite question (click again to undo) I interpret this as saying, if you click this button it will be a favourite question and if you click it again it will be unfavourited. I agree that this is possibly not the best way of expressing it, particularly if you are not a ...

This answer seems to suggest there are no ads on Chemistry (except for the sidebar) and the privilege is therefore hidden: The privilege exists everywhere. But on most sites, it's hidden and notifications for earning it are suppressed. Doesn't make much sense to tell folks about a privilege that doesn't actually do anything. Here is another answer which ...

You'll need a so-called positive question record for the Curious badge and related badges. A positive question record means you don't have too many closed, downvoted or deleted questions, overall. The formula is (total questions - negative questions - closed - deleted)/total questions ≥ 0.5` Questions that have been downvoted and closed and deleted count ...

According to this post on MetaSE, the issue has been discovered and a solution is enroute. From Marc Gravell, an SE staff member, Sorry about that. What happened here: the favorites/ignored feature is implemented client-side; a UI tweak changed the DOM in a way that broke the jQuery selector, meaning that it no longer found the tag data. I've put a PR ...

This has happened to me too. The closest I found on mother meta is this post: Old first post reviews on sites without audits enabled There's something similar on meta.SO: Old first posts in first posts queue So Shog's answer basically says that when either a user's first post gets deleted a user's reputation is dramatically affected due to bounties, spam ...

I will look into it a bit further, but it appears as though the help page is interpreting the <=> symbol as an HTML tag, and is therefore not rendering it properly.

Indeed, there was a missing MathJax extension. This will be fixed in the next update to the iOS app in the Appstore.

This feature is poorly documented on meta, so rather than waiting 6 to 8 weeks for documentation to arrive here is the full documentation: Users who have the access review queue priviledge but not the editing priviledge (A.k.a. $x < 2~\mathrm{krep}$; $x$ being the user’s reputation) These users do not see that orange box. Users with the editing ...
