Calcium carbonate is heat at very high temperatures (near 1000°C) and it decomposes into Calcium oxide and Carbon dioxide:
CaCO3 --Δ--> CaO + CO2
When water is added to Calcium oxide, the Calcium hydroxide is formed:
CaO + H2O ----> Ca(OH)2
This can be again converted back to Calcium carbonate, by blowing Carbon dioxide through the solution. The white precipitate is Calcium carbonate:
Ca(OH)2 + CO2 ----> CaCO3 + H2O

∙ 12y agoThis one's easy--just apply sufficient heat to CaCO3 to cleave the molecule, forming CaO and CO2. The process is commonly used for manufacture of quicklime, cement, etc. The process has been utilized for cement manufacture for at least 2000 years.

Ca(OH)2 + CO2 --> CaCO3 + H2O

How do you measure the amount of carbonate in a rock?
hydrochloric acid + calcium carbonate ▬▬► calcium chloride + carbon dioxide + water
What happen when carbon dioxide gas is passed though lime water which compound is formed?
Calcium bicarbonate and calcium carbonate.
What is the equation for heating calcium carbonate?
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
Does calcium carbonate thermally decompse?

What happens to calcium carbonate when heated?
It decomposes into calcium oxide and carbon dioxide
What is formed when calcium carbonate decomposes?
quicklime (calcium oxide) is formed when calcium carbonate decomposes, as well as releasing carbon dioxide
Calcium carbonate is heated to from calcium oxide and carbon dioxide well balanced equation?
