# What is an example where heating a substance provides a mixture of its constituent elements?

Feb 20, 2016

You might have to be a bit more specific, but I can give 1 example where the heating of a compound gives an elemental mixture, that of cinnabar.

#### Explanation:

Cinnabar is bright red mercuric sulfide. Heating decomposes this material to give mercury metal and sulfur.

$H g S \left(s\right) + \Delta \rightarrow H g \left(l\right) + S \left(s\right)$

The mercury metal may be collected by decantation, and then redistillation.
