Typesetting chemical reaction equations

Typesetting chemical reaction equations

[Tayebe Bagheri]

I need the reaction of NTG with limestone.

Typesetting chemical reaction equations

[Ville Voipio]

I would need to typeset some rather simple reaction equations. I do not 
need the structural capabilities of PPCHTeX, just something simpler. The 
thing I am writing has something to do with physical chemistry, so I 
need mathematical equations, as well.

Of course, the natural way to do this:

\placeformula
\startformula
   \rm
   NH_3(g) + H^+(aq.) + Cl^-(aq.) \rightarrow NH_4^+(aq.) + Cl^-(aq.)
\stopformula

This gives rather pleasant-looking results. However, is this the right 
(i.e. kosher) way of doing things, or do I run into trouble at some 
later point with this? What are you chemists using?

And how do I switch off the equation numbering for the chemical 
reactions (I'd like to have the mathematical formulae still numbered)?

TIA,

- Ville

\usemodule[chemic]

\placeformula[-]
\startformula
   \chemical{NH_3(g),+,H^+(aq.),+,Cl^-(aq.),->,NH_4^+(aq.),+,Cl^-(aq.)}
\stopformula

Graag gedaan 

btw, this is documented in the ppchtex manual

Stupid me. Just by leaving the \placeformula out. (Maybe I should go and 
get something to eat, my brain seems to be in some sort of energy-saving 
mode.)

By the way, is there a simple way to have two separate numbering 
schemes? If I wanted to have chemical formulae numbered with 1,2,3,4... 
and maths with i, ii, iii, iv, ... , how should I do it? It must be 
documented with \placeformula, but is \placeformula documented anywhere 
apart from the code itself? (Yes, I am lazy.)

well, i can make a \defineformulaplacement; remind me
