The burning splint is extinguished by the carbon dioxide given off from the calcium carbonate.
CaCO3 --heat--> CaO + CO2
==================================================
It decomposes into calcium oxide and carbon dioxide
Here is the reaction:CaCO3(s) ==heat==> CaO(s) + CO2(g) So, when calcium carbonate is heated, you get calcium oxide and carbon dioxide gas.
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
calcium carbonate, acetaldehyde and 2-hydroxy propanal

Limestone, which contains calcium carbonate, is heated in a kiln to produce lime. This lime is a key ingredient in the production of cement when mixed with other materials such as sand and water.
When calcium carbonate is heated, it breaks down by thermal decomposition to carbon dioxide & calcium oxide (quicklime). Here is the word equation: Calcium carbonate --> Calcium oxide + Carbon dioxide Here is the chemical equation: CaCO3 (s) --> CaO (s) + CO2 (g)
The reaction of calcium carbonate being heated into calcium oxide and carbon dioxide is an endothermic reaction because it requires the input of energy to break the bonds in the calcium carbonate molecule and form the products.
carbon dioxide is produced when it is heated
Calcium carbonate heated to form calcium oxide and carbon dioxide as shown by the equation CaCO3(s) → CaO(s) + CO2(g).
Calcium carbonate is heated to from calcium oxide and carbon dioxide as illustrated by the chemical equation CaCO3(s) ===> CaO(s) + CO2(g).
