(a) Complete the following chemical reaction equations :
(i) `P_(4) + SO_(2)Cl_(2) rarr`
(ii) `XeF_(6) + H_(2)O rarr`
(b) Predict the shape and the asked angle (`90^(@)` or mor or less) in each of the following cases :
(i) `SO_(3)^(2-)` and the angle `O-S-O`
(ii) `ClF_(3)` and the angle`F-Cl-F`
(iii) `XeF_(2)` and the angle `F - Xe - F`

Explanation

(a) (i) `P_(4) + 8SO_(2)Cl_(2) rarr 4PCl_(3) + 4SO_(2) + PS_(2)Cl_(2)`
(ii) `XeF_(6) + H_(2)O rarr 2HF + XeOF_(4)`
(b) (i) Structure :

Shapeof `SO_(3^(2-))` pyramidal.
Bond angle `rarr` More than `180^(@)`.
(ii) Strucutre:

`ClF_(3) rarr` Bent T - shape Bond angle = More than `90^(@)`.
(iii) Structure
