Question

The white solid compound A decomposes quite rapidly on heating in the presence of a black substance X to form a solid compound B and a gas C. When an aqueous solution of compound B is reacted with silver nitrate solution, then a white precipitate of silver chloride is obtained along with potassium nitrate solution. Gas C does not burn itself but helps to burn other things.
What is gas C?

Solution

$2 K C l O_{3} + M n O_{2} ⟶ 2 K C l + 3 O_{2}$
Compound A=Potassium chlorate
Compound B=Potassium chloride
Gas C=Oxygen
Black substance X=Manganese dioxide
General name of substance X=catalyst
$M n O_{2}$ acts as a catalyst in decomposition.
