Question

During the thermal decomposition of calcium carbonate one product is obtained which is used by plants to make their food . name this product?​

Answer 1

Answer:

CO2

Explanation:

Calcium Carbonate = CaCO3

After thermal decomposition;

CaCO3 + Heat ====== CO2 + CaO

Here CO2 and CaO are product in which Carbon dioxide (CO2) is used by plants to make food.

Answer 2

Carbon dioxide is the product of the thermal decomposition of calcium carbonate which is used by plants to make their food.

• When calcium carbonate is decomposed,two chemical products are formed - calcium oxide and carbon dioxide gas.

CaCO3 + ∆ -----> CaO + CO2

• Now,the calcium oxide is not necessary for the food making process of the plants or the photosynthesis.

• But, carbon dioxide gas is widely used in the photosynthesis of the plants.

• So, carbon dioxide gas is the product of the thermal decomposition of calcium carbonate which is necessary for the photosynthesis of the plants.
