CaCO 3 (s). CaO(s) + CO 2 (g). This reaction is reversible; calcium oxide will react with carbon dioxide to form calcium carbonate. The reaction is driven to the right by flushing carbon dioxide from the mixture as it is released.The production of calcium oxide from limestone is one of the oldest chemical transformations produced by man.aCO 3 (s).
