Lab# Thermal Decomposition of Calcium Carbonate

In addition when heated above 840°C calcium carbonate decomposes releasing carbon dioxide gas and leaving behind calcium oxide a white solid The thermal decomposition of calcium carbonate to lime is one of the oldest chemical reactions known For several thousand years lime has been used in mortar a paste of lime sand and water to cement stones to one another in buildings walls
