CaO can be used as a drying agent. One such application occurs when water is added to dry concrete or cement. The reaction that occurs isSubstanceCaO(s) + H2O(l) = Ca(OH)2(s)
The product is commonly called slaked lime.Assuming standard temperature, calculate for this reaction using table from the table below.
