What chemicals won't mix together?
<|assistant|>
Some chemicals don't mix because they can become highly reactive when combined. Examples of chemicals that do not react well together include: sodium and chlorine, hydrogen and chlorine, and nitrogen and fluorine. Additionally, some metal elements, such as iron and magnesium, should not be in the same container or tank due to the risk of sparks or chemical reactions that can lead to an explosion.
