Question about Science & Laboratory
I suggest taking some chemistry courses if you are really interested as there are far too many combinations that can be dangerous. Peroxides, Perchlorates, Nitrates the list is too long to enumerate. if you don't know what you're doing then don't do it until you do.

I actually just did a lesson on this with my students. When the chemical hand warmer is removed from the outer packet and exposed to oxygen, it produces an exothermic chemical reaction, which is a reaction that gives off heat. The result of this reaction is iron oxide or rust.
