Outline the limestone cycle including the relevant equations.
Calcium carbonate undergoes thermal decomposition to form calcium oxide and carbon dioxide.
Calcium Oxide (CaO) can undergo an exothermique réaction with water to product Calcium Hydroxide, also known as slaked lime, Ca(OH)2.
The final regeneration step involves the reaction of slaked lime with Carbon dioxide to form the Calcium Carbonate (limestone) once more.
