Na2O + H2O → 2NaOH Na2O + Na2O2 xrightarrow[at 25°c]H2O NaOH + O2 uparrow

Q. $A + H_{2} O \to N a O H$
$A + B H_{2} O a t 2 5^{\circ} c N a O H + O_{2}$
$B$ is used
for oxygenation in submarines $A$ and $B$ are respectively:

$N a_{2} O_{2}$ and $N_{2} O$

$2 N a_{2} O$ and $N a_{2} O_{2}$

$N a_{2} O_{2}$ and $O_{2}$

$N a_{2} O$ and $O_{2}$

$N a_{2} O + H_{2} O \to 2 N a O H$
$N a_{2} O + N a_{2} O_{2} H_{2} O a t 2 5^{\circ} c N a O H + O_{2} ↑$
