Calcium Oxide

This is accomplished by heating the material to about 825 176 C a process called calcination or lime burning to liberate a molecule of CO 2 leaving quicklime This process is reversible since once the quicklime product has cooled it immediately begins to absorb carbon dioxide from the air until after enough time it is completely converted back to calcium carbonate...
