Complete the following equations :
(i) `P_(4)+H_(2)Orarr`
(ii) `XeF_(4)+O_(2)F_(2)rarr`

Explanation

Direct reaction is not possible. The medium should be either acidic or basic.
Acidic Medium :
`2P_(4)+12H_(2)Orarr 4PH_(3)+4HPO_(3)^(2-)+8H^(+)`
Basic Medium :
`2P_(4)+4H_(2)O+8OH^(-)rarr 4PH_(3)+4HPO_(3)^(2-)`
(i) `P_(4)+H_(2)Orarr"no reaction"`
(ii) `XeF_(4)+O_(2)F_(2)rarr XeF_(6)+O_(2)`
