carbondioxide
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.
calcium carbonate (limestone)
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
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.
It decomposes into calcium oxide and carbon dioxide
carbon dioxide is produced when it is heated
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)
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).
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
