Complete the following chemical equations :
(i) `Ca_(3)P_(2)(s) + H_(2)O(l) rarr.........`
(ii) `Cu^(2+)(aq) + underset(("excess"))(NH_(3)(aq))rarr.........`
(iii) `F_(2)(g) + H_(2)O(l) rarr ..........`

Explanation

(i) `Ca_(3)P_(2)(s) + H_(2)O(l)rarr3Ca(OH)_(2)(aq)+2PH_(3)(g)`
OR
`Ca_(3)P_(2)+ 6H_(2)Orarr3Ca(OH)_(2)+2PH_(3)`
(ii) `underset("blue ")(Cu^(2+))(aq)+4NH_(3)(aq)iffunderset("deep blue")([Cu(NH_(3))_(4)])^(2+)(aq)`
(iii) `2F_(2)(g) + 2H_(2)O(l) rarr 4H^(+)(aq) + 4F^(-)(aq) + O_(2)(g)`
