When calcium carbonate is heated it is changed into calcium oxide and carbon dioxide.
Explanation:
- the main energy for the decomposition reaction usually comes from heat and it is known as thermal decomposition. We should first take calcium carbonate crystals. Then it is exposed to heat suddenly , we can find that the fumes of carbon dioxide is coming out.
- Calcium oxide can be seen as the precipitate which occurs at the bottom of the frame the balance chemical reaction of the equation is given below
CaCO3(s) → CaO + CO2(g)
To know more about thermal decomposition,
decomposition brought about by heat is known as thermal .
