What happens to the solidity of calcium carbonate is heated?

Answer 1

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)

Answer 2

When calcium carbonate is heated, it undergoes thermal decomposition to produce calcium oxide (quicklime) and carbon dioxide gas. This process occurs around 825°C and the solid calcium carbonate breaks down into a solid and a gas.

Answer 3

Calcium Carbonate, when heated, compleatly decomposes to make Calcium Oxide and Carbon Dioxide. CaCo3----->CaO + CO2

Answer 4

all metal carbonates give their oxides & CO2 except alkali metals (K,Na).

Answer 5

It becomes calcium oxide and because smaller and is less hard

Answer 6

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.
