Solution

$Reaction of sodium peroxide (N a_{2} O_{2}) with water$

When sodium peroxide is dissolved in water, it is readily hydrolyzed to form sodium hydroxide and hydrogen peroxide.

Involved reaction: $N a_{2} O_{2} (s) + H_{2} O (l) \to N a O H (a q) + H_{2} O_{2} (a q)$

Balanced reaction:

$2 N a_{2} O_{2} (s) + 2 H_{2} O (l) \to 4 N a O H (a q) + H_{2} O_{2} (a q)$

Hence, in above reaction all the atoms are equal on both the sides, so our chemical reaction is well balanced.

$Final answer:$
Balanced reaction:

$2 N a_{2} O_{2} (s) + 2 H_{2} O (l) \to 4 N a O H (a q) + H_{2} O_{2} (a q)$

$Reaction of Potassium superoxide (K O_{2}) with water$

When potassium superoxide reacts with the water the products formed are the potassium hydroxide, oxygen, and hydrogen peroxide.

Involved reaction: $K O_{2} (s) + H_{2} O (l) \to K O H (a q) + H_{2} O_{2} (a q) + O_{2} (g)$

Balanced reaction: $2 K O_{2} (s) + 2 H_{2} O (l) \to 2 K O H (a q) + H_{2} O_{2} (a q) + O_{2} (g)$

Hence, in above reaction all the atoms are equal on both the sides, so our chemical reaction is well balanced.

$Final answer :$
Balanced reaction:
$2 K O_{2} (s) + 2 H_{2} O (l) \to 2 K O H (a q) + H_{2} O_{2} (a q) + O_{2} (g)$

$Reaction of Sodium oxide (N a_{2} O) with carbon dioxide (C O_{2})$

Sodium oxide $(N a_{2} O)$ react with carbon dioxide $(C O_{2})$ to produce sodium carbonate $(N a_{2} C O_{3})$ . This reaction takes place at a temperature of $450 - 550^{\circ} C$

Involved reaction: $N a_{2} O (s) + C O_{2} (g) \to N a_{2} C O_{3} (s)$

Balanced reaction:
$N a_{2} O (s) + C O_{2} (g) \to N a_{2} C O_{3} (s)$

Hence, in above reaction all the atoms are equal on both the sides, so our chemical reaction is well balanced.

$Final answer:$
Balanced reaction:
$N a_{2} O (s) + C O_{2} (g) \to N a_{2} C O_{3} (s)$
