### Placing Text Between Equations

Hi everyone! First post. I'm very new to LaTeX and just started a couple of days ago. I'm trying to write a series of equations and I want to place text between them, but when I put the text in math mode it numbers it like an equation. If I put the text outside of the math mode I get a huge gap between the text and equations. For example:

\begin{align}
eqn1 \\[10pt]
eqn2
\end{align}
\begin{center}
or
\end{center}
\begin{align}
eqn3
\end{align}

I'm guessing the spacing has something to do with the template I downloaded. Any help would be great! Thanks!

Are you searching for \intertext{}?

\documentclass{article}\usepackage{mathtools}\begin{document} \begin{align}eqn1 \\[10pt]eqn2\\\intertext{\centering text}eqn3\end{align}  \end{document}

Yes, that works great, but is there a way to shorten the distance between the text and equations? It's still obnoxiously large. Thank you for the reply, by the way!

can you show some example code that produces obnoxiously large spacing? I only get the usual above and below display skip in my example.

The attached picture is what it looks like. It might be the same spacing between each line, but it doesn't look right that the second and third equations are so far apart.

Sorry is that enough code? I'm not exactly sure how to use this forum either...

Your output looks just as it should. If you really want to reduce the space:

\documentclass[review]{elsarticle} \usepackage{lineno,hyperref,upgreek,graphicx,chemformula,subfig}\modulolinenumbers[5] \begin{document}  \begin{align}\ch{Ce + H_2 -> CeH_2}, \qquad \qquad \Delta &G_{rxn}^\circ=-115 kJ/mol \\[10pt]\ch{CeH_2 + 2.5Cl_2 -> CeCl_3 + 2HCl}, \qquad \qquad \Delta &G_{rxn}^\circ=-1007 kJ/mol\\[-40pt]\intertext{\centering or \vskip-20pt}\ch{CeH_2 + 1.5Cl_2 -> CeCl_3 + H_2}, \qquad \qquad \Delta &G_{rxn}^\circ=-812 kJ/mol\end{align} \end{document}

Perfect! I didn't know you could put negative values in spacing. Thank you so much!

You should try \shortintertext of package mathtools first.
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.
