I have a small problem with arrows. I need a `\rightarrow`

with a `\Delta`

on it. Can you help me, please? I use the chemistry package `\usepackage[version=3]{mhchem}`

.

# [Tex/LaTex] Rightarrow with a Delta on it (for use with the mhchem package)

## Best Answer

`mhchem`

's formulas implicitly use math mode so you can use`\Delta`

directly. The syntax inside`mhchem`

's`\ce{}`

macro for a right arrow is:where both arguments are optional and

`above`

and`below`

are placed in math mode. (`mhchem`

also loads`amsmath`

by the way.)The

`mhchem`

manual actually has an example for this :)
