Question

Find x in the following equation
x+2H2o -----y+2H2 solutions Y is treated with carbon dioxide to produce white turbidity

​

Answer 1

Answer:

The thermal decomposition of calcium carbonate (X) gives calcium oxide and carbon dioxide.

CaCO3(X)→CaO+CO2

The hydrolysis of calcium oxide gives calcium hydroxide (Y).

CaO+H2O→Ca(OH)2(Y)

Calcium hydroxide reacts with carbon dioxide to form soluble bicarbonate (Z).

Ca(OH)2(Y)+2CO2→Ca(HCO3)2(Z)

On boiling, calcium bicarbonate decomposes to form calcium carbonate, water and carbon dioxide.

Ca(HCO3)2(Z)BoilingCaCO3(X)+H2O+CO2
