are correct. 2FeCl 3 2FeCl 2 + Cl 2. The chemical reactions we have described are only a tiny sampling of the infinite number of chemical reactions possible. Combination reactions can also take place when an element reacts with a compound to form a new compound composed of a larger number of atoms.
