Canvas Equation Editor Tips: Chemistry

Find your school's Canvas URL

To find your school or institution's Canvas URL, begin typing the name of your school/institution. Results will appear after you type at least 3 characters. For best results be as specific as possible. If you can't find your school, try using any part of your school's name or searching for your school district or state. You may also need to search for the school using the acronym or full name, for example "USU" and "Utah State University".

Canvas Equation Editor Tips: Chemistry

This document details how to write chemical formulas and equations using the Advanced View of the Canvas Equation Editor.


Writing Chemical Formulas

You can use the advanced view in the equation editor to write chemical formulas. For formula writing, use _ (underscore) for subscripts and ^ (carat) for superscripts. If there is more than one character in the subscript or superscript, wrap the characters with braces { }. If you’d like your chemical formulas without the italics, use advanced view and \text{ } to enclose the elements.

\text{Al}_3(\text{SO}_4)_2


Writing Scientific Notation

There are two ways to write the times symbol: \times and \cdot. Use ^ for exponents. If the exponent contains more than one character, place the exponent text in braces { }. Use \text{ } wrapped around units to remove the italicization. Use \space to place space between numbers and units.

Writing Chemical Equations

To write chemical equations, you’ll need to use a variety of reaction arrows. Here’s a short list of arrows that can be used in the advanced view of the equation editor.

Using the advanced view, we can write equations like the following examples. You may wish to use \space to provide space between quantities and chemical formulas. If you want to remove the italicized elements, it is usually easier to write the formula first, and then go through and insert \text{ } around all the elements in the formula.
