Question

$A + H_2O \to NaOH$
$A +B \xrightarrow[{at\, 25^{\circ}c}]{H_2O} NaOH + O_2$
$B$ is used
for oxygenation in submarines $A$ and $B$ are respectively:

• A. $Na _{2} O _{2}$ and $N _{2} O$
• B. $2 Na _{2} O$ and $Na _{2} O _{2}$
• C. $Na _{2} O _{2}$ and $O _{2}$
• D. $Na _{2} O$ and $O _{2}$

Answer 1

Answer: (B)

$Na_2O + H_2O \to 2NaOH$
$Na_2O + Na_2O_2 \xrightarrow[{at 25^{\circ}c}]{H_2O} NaOH + O_2 \uparrow$
