Question

compound X decomposes to form compound Y and CO2 gas. compound Y is used in manufacturing of cement.
(a) name the compound X and Y.
(b) write the chemical equation for this reaction.

Answer 1

compound y is CaO
compound x is CaCO3
CaCO3---> CaO+CO2

Answer 2

(a) Name of the compounds X and Y are Calcium Carbonate $\bold{\left(\mathrm{CaCO}_{3}\right)}$ and Calcium Oxide (CaO)

(b) The chemical equation for this reaction is as follows:

$\bold{\mathrm{CaCO}_{3} \rightarrow \mathrm{CaO}+\mathrm{CO}_{2}}$

From the reaction, Calcium oxide and carbon dioxide are produced.

Calcium carbonate is used in heavy construction work. Calcium oxide is in diverse ways.

It finds application in medicine, agriculture (as insecticides), in steel and paper manufacturing and in chemical experiments for performing tests involving precipitation or dehydration.
