Complete the following equations :
(i) `Na_(2)O_2+ 2H_(2) O to (W) +H_(2)O_(2)`
(ii) `2KO_(2)+2H_(2)O to (X) +(Y) +O_(2)`
(iii) `Na_(2) O+ CO_(2)to (Z).`

Options

A. `{:(W, X , Y , Z) , (4Na , K_(2)O , H_(2)O_(2) , Na_(2)CO_(3)):}`
B. `{:(W, X , Y , Z) , (4Na , K_(2)O , H_(2)O_(2) , Na_(2)CO_(3)):}`
C. `{:(W, X , Y , Z) , (4NaOH , 2KOH , H_(2)O , Na_(2)O_(2)):}`
D. `{:(W, X , Y , Z) , (2NaOH , 2KOH , H_(2)O_(2) , Na_(2)CO_(3)):}`

Answer

D

Explanation

`Na_(2)O_(2)+ 2H_(2)O to underset((W))(2NaOH)+ H_(2)O_(2)`
`2KO_(2)+ 2H_(2)O to underset((X))(2KOH)+ underset((Y))(H_(2)O_(2))+ O_(2)`
`Na_(2) O+CO_(2) to underset((Z))(Na_(2) CO_(3))`
