Sorry that I wasn't clear. On the call, we discussed the need for both ChemFormula and ChemEquation subjects. I wondered if both were necessary, and so someone (via screen share) drew an example where both were needed. The example I think was an equilibrium equation where at least one of the formula involved using the single/double bond notation that overloads equals/double bond and minus/single bond. So "=" appeared that was used both ways; I'm not sure if there was also a "-" used both ways, but some example that used both in the two different senses would be even better than an example that used only one symbol both ways (note: the ion notation isn't really an overload as its meaning is clear in the superscript position of an element).  None of the examples in Elane's link (https://docs.moodle.org/38/en/Chemistry_notation_using_mhchem<https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.moodle.org_38_en_Chemistry-5Fnotation-5Fusing-5Fmhchem&d=DwMFaQ&c=7ypwAowFJ8v-mw8AB-SdSueVQgSDL4HiiSaLK01W8HA&r=YiYALifqdGEodVD1FsQilY_ldzZTpIdTA4hktnLgJSM&m=E64KFNfhibL0juLr5mjJmzNbWjZ3TJlE2mSa8_8Sk8Q&s=fiFp0d0pIvX4xRKdKX1TpSdp0xs5eqBrVjX31CEn2Qg&e=>) do that. I like to use "real" examples rather than ones that don't make sense, and my Chemistry knowledge is too rusty to remember bonds, hence my request.

Thanks,

    Neil

Hi, Neil,



We can give you examples, but I’d have no idea how to do it in MathML.



Our group is meeting today and, hopefully, we can come up with something.



Dan

________________________________

On the last call, someone had a nice example of chemical formulas using single/double bonds inside of a chemistry expression. Can someone send an example to me either via TeX or (preferably) MathML? The MathML CG is going to write up some examples of where adding semantics helps AT and that is a good example outside of the math domain.



Thanks,



    Neil
