WebAssign allows you to display chemical formulas as images. This feature is useful for displaying chemical compounds, electron configurations, reactions, and nuclear isotopes. The full power of randomizing variables and numbers is retained in generating the chemical formulas. Functions are entered as plain text. Subscripts are implied and superscripts must be preceded by a caret (^).

When students are required to input an answer in WebAssign, they can preview their answer using the same method.

To try out this feature, type in your chemical formula in the box.
