Vedclass · Answer

(B) The thermal decomposition of sodium oxide $(Na_2O)$ at $400 \ ^oC$ is given by the reaction:$2Na_2O ightleftharpoons Na_2O_2 + 2Na$Here,$A$ is sodium peroxide $(Na_2O_2)$.Sodium peroxide reacts with sulfur dioxide $(SO_2)$ to form sodium sulfate $(Na_2SO_4)$:$Na_2O_2 + SO_2 	o Na_2SO_4$Sodium peroxide reacts with carbon monoxide $(CO)$ to form sodium carbonate $(Na_2CO_3)$:$Na_2O_2 + CO 	o Na_2CO_3$Thus,$A$ is $Na_2O_2$.

$2Na_2O \overset{400 \ ^oC}{\rightleftharpoons} A + 2Na$
$A + SO_2 \to Na_2SO_4$
$A + CO \to Na_2CO_3$
In the above reaction,$A$ is:
