We can also write the names of substances underneath them by using a ! and two pairs of parentheses. This code:
\begin{Verbatim}[]
\ch{!( sodium )( $2n$ Na ) + !( chlorine )( $n$ Cl2 ) -> !( s
odium\ chloride )( $2n$ NaCl )}
\end{Verbatim}
gives us this example:
\vspace{\baselineskip}
\noindent{}\ch{!( sodium )( $2n$ Na ) + !( chlorine )( $n$ Cl2 ) -> !( sodium\ chloride )( $2n$ NaCl )}
\vspace{\baselineskip}
Notice that we had to use spaces inside the parentheses so that the package will know how to format these separate types of input. Also, because a space delineates different inputs, in order to get that space in ``sodium chloride'' we had to escape the space with a backward slash.
Again, there are lots of options to customize the output. Here's one with fractions: Again, there are lots of options to customize the output. Here's one with fractions:
\begin{Verbatim}[] \begin{Verbatim}[]
\ch{3/2} \ch{3/2} (vertical fraction) \quad

Like I said, this one operates a lot like \texttt{mhchem}. If \texttt{mhchem} works for you, there's no need to look further. But if you need more control over the appearance of your formulas and equations, \texttt{chemformula} will give you a lot of that control.
