Answer 2

When calcium carbonate is heated, it decomposes to give__calcium oxide___ and __carbon dioxide ___.

• Calcium carbonate on heating decomposes to calcium oxide and carbon dioxide.
• The balanced reaction is as follows-
• $CaCO_3\rightarrow CaO+CO_2$.
• One mole of calcium carbonate on heating produces one mole of calcium oxide along with one mole of carbon dioxide gas.
• Thus on heating, the products of calcium carbonate are calcium oxide and carbon dioxide gas.
