Carbon dioxide makes lime water milky.
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
When calcium carbonate is heated, it undergoes thermal decomposition to produce calcium oxide and carbon dioxide. This reaction releases the carbon that was originally part of the calcium carbonate as carbon dioxide gas.
carbon dioxide is produced when it is heated
It decomposes into calcium oxide and carbon dioxide
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).
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.
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
It decomposes into calcium oxide and carbon dioxide...
Calcium Carbonate + Heat ------------ Calcium Oxide + Carbon Dioxide
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)
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.
