Which is the correct set of products formed when calcium carbonate is heated?
Answer and explanation
Correct answer: Calcium oxide and carbon dioxide
On heating, calcium carbonate undergoes thermal decomposition to form calcium oxide and carbon dioxide:
\(\mathrm{CaCO_3 \xrightarrow{\Delta} CaO + CO_2}\).
Therefore, option A is correct. Option B is incorrect because calcium hydroxide and oxygen are not the products formed by heating calcium carbonate.
