Here's why:
* Organic compounds typically contain carbon atoms bonded to hydrogen atoms, often along with oxygen, nitrogen, and other elements. They are often complex molecules derived from living organisms.
* Inorganic compounds are made up of elements other than carbon and hydrogen, or of simple carbon-containing compounds like carbon dioxide (CO₂).
Calcium chloride is a salt formed from the reaction of a metal (calcium) and a nonmetal (chlorine), fitting the definition of an inorganic compound.
