Which of the following is not sublimable?
Dry ice
Calcium chloride
Ammonium chloride

Calcium chloride

Explanation:

Sublimation is the process whereby a solid substance is converted to gas when heat is applied. Solid normally gets converted to the liquid phase before reaching the gaseous phase but these substances gets converted from solid straight to gas
