I have a question, How to nullify hydrogen sulphide smell with human friendly chemical? Thanks

reactivity

Why's this too broad?

Did they pull out support for aligned equations

My profile description isn't working and sometime back when I tried to align the equations on the main site that didn't work either

@mhchem isn't pingable here anymore :/

Anyway, something is odd with the my triple bonds. The vertical spacing between the three vertical lines is not uniform. Here's a screenshot:

This is at 100% zoom level on Chrome 67 Win 10. Notice that in the above screenshot, only \huge has the correct vertical spacing.

Can any mod (@Loong, are you there?) please super-ping mhchem? Thanks

@AvnishKabaj that's odd, I can't get it to work either. I guess & is not allowed inside \mathrm{}. So, you should replace that \mathrm{} with \ce{}, and it works!

@GaurangTandon "three horizontal lines" facepalm

@GaurangTandon \ce{} wasn't working so I switched to mathrm

@AvnishKabaj ah, I see. Use this then:

\begin{align}
\text{Av} &\rightarrow \text{Uv}\\
\text{Ni} &\rightarrow \text{Knee}\\
\text{Sh} &\rightarrow \text{Sh}\\
\text{Ka} &\rightarrow \text{Kuh}\\
\text{Baj} &\rightarrow \text{Badge}\\
\end{align}

\ce isn't enabled for all SE sites, probably why it didn't work

@GaurangTandon thaaaaaanks

Thaaaaaanks

sure, np

That worked just right

@harambe you would need to add the exact steps that you used to reach the final values. Until you add those steps, I cannot help much :(

Q: Mixture with 2 turning points

4:14 PM

50 mL of two weak acids HA 0.08M and 0.12M and respectively pka1=4.2 and pka2=8.4 are mixed and valorated with NaOH 0.2M. How to find the pH at the two equivalence points?

acid-base

another conceptual question that probably would have to be closed... :(

@GaurangTandon done

@harambe now this is an interesting question! :)

Don't know what they are asking about tbh.

Maybe P-V graph for gas A
