You typed in your TeX-file:

   \placeformula
   \startformula
   \chemical{2H_2}{hydrogen}
   \chemical{PLUS}
   \chemical{O_2}{oxygen}
   \chemical{GIVES}{heat}
   \chemical{2H_2O}{water}
   \stopformula

The \placeformula and \start..\stopformula are ConTeXt commands. In LaTeX
they have no meaning.

Try in stead:

$$
   \chemical{2H_2}{hydrogen}
   \chemical{PLUS}
   \chemical{O_2}{oxygen}
   \chemical{GIVES}{heat}
   \chemical{2H_2O}{water}
$$
