CaCO3(s) ==heat==> CaO(s)+CO2(g)
The correct chemical expression you need is NOT 'heated' , but 'Thermal Decomposition'.
Calcium carbonate when heated to about 900 oC ( red glowing heat) will undergo thermal decomposition , to form calcium oxide((quick)lime) and carbon dioxide.
Visually, you don't see anything. Calcium carbonate is white in coliur as is Calcium Oxide. You do not see carbon dioxide being given off.
The only way to check is by weighing the mass of calcium carbonate. Heat it. Re-weigh when cool. It shoulk be of less weight. The difference being the mass of CO2 liberated, which you cannot weigh.

What is heated with calcium carbonate to make cement?
calcium carbonate :)
How can you distinguish calcium carbonate from other deposits?
The chemical formula of calcium carbonate is CaCO3. It emits CO2 when heated. This gas tuns lime water into milky white when reacted.
When solid calcium carbonate is heated what is form?
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
What does Calcium Carbonate Decomposes To Form?
CaCo3 heated & gives CaO+Co2
What happen when lead carbonate is heated?
carbonate reactions when heated
Calcium carbonate is heated to from calcium oxide and carbon dioxide well balanced equation?
Calcium carbonate is heated to from calcium oxide and carbon dioxide as illustrated by the chemical equation CaCO3(s) ===> CaO(s) + CO2(g).
Calcium carbonate heated to from calcium oxide and carbon dioxide well balanced equation?
Calcium carbonate heated to form calcium oxide and carbon dioxide as shown by the equation CaCO3(s) → CaO(s) + CO2(g).
Balanced equation of calcium carbonate while heated?
Ca(ClO3)2 ---> CaCl2 + 3O2 is the balanced equation when calcium chlorate is heated.

When solid calcium carbonate is heated what is form?
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
When calcium carbonate is heated what does it make?
milk =]
What happens to calcium carbonate when heated?
It decomposes into calcium oxide and carbon dioxide
What substances are created when calcium carbonate is heated very strongly in an open crucible?
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
When calcium carbonate is heated what gas is given off?
carbon dioxide is produced when it is heated
What happens when calcium lactate is heated?
calcium carbonate, acetaldehyde and 2-hydroxy propanal
What is the substance that is heated with calcium carbonate to make cement?
carbondioxide
