\startchemicalformula
not
\startformula
\startchemicalformula
\chemical{2H_2}
\chemical{PLUS}
\chemical{O_2}
\chemical{GIVES}
\chemical{2H_2O}
\stopchemicalformula
Also, the shorthand "+" for "PLUS", "->" for "GIVES", etc.
seems to be interpreted only inline, not in displayed chemical formula
mode.
I am working (with Hans) to correct the mkiv chemical code,
which has been completely re-written (from ppchTeX macros).
Also working on a new manual, at the same time...
