Biology and Chemistry have the mhchem MathJax extension enabled, which makes it easier to write chemical species and reactions. Should this extension be enabled here? I imagine that it will be useful for some questions in geochemistry, at minimum.

It's now possible describe stratospheric ozone with equations:
$$ \ce{O2 ->[\text{uv light}] 2 O}\\ \ce{O2 + O -> O3} $$
Some helpful information:
- A guide on the basics of mhchem.
- Resist the urge to overuse $\TeX$.
Other than that... enjoy!

List of questions that would benefit from mhchem:
- Peak phosphorus - what are the sinks?
- What would happen if we could revert $\mathrm{CO}_2$ production but took it too far?
- How were we able to measure carbon dioxide levels in earlier climates?
- How does radiogenic argon-40 get into the atmosphere? (features a reaction)
- How does one create petroleum/crude oil for future generations?
- What is the mechanism behind changes in oxidation state (of iron, for example) as magma rises?
- What makes the conditions at the core/mantle boundary ideal for aluminum to combine with other elements besides oxygen?
- What is it about ancient craton geology that results in associated kimberlite pipes containing economic diamond deposits?
- What's the difference between the upper & lower mantle? (features a reaction)
(Please edit this answer with any other questions that would benefit from mhchem.)

3$\begingroup$ Examples are good. It would also be helpful to have examples where chemical reactions (more than just naming molecules) being written would improve the posts. Once we get a few more examples I'll make sure a CM sees this. $\endgroup$– caseyMay 23, 2014 at 0:55
