Question

Complete the following
(i) `PbS(s)+H_(2)O_(2)(aq) to ` (ii) `MnO_(4)^(-)(aq)+H_(2)O_(2)(aq)+H^(+)(aq)to`
`CaO_(s)+H_(2)O(g) to ` (iv) `AlCl_(3)(s)+H_(2)O(l) to`
(v) `Ca_(3)N_(2)(s)+H_(2)O(l) to `

Answer 1

`(i)PbS(s)+4H_(2)O_(2)(aq) to PbSO_(4)(s)+4H_(2)O(aq)`
(ii) `2MnO_(4)^(-)(aq)+6H^(+)(aq)+5H_(2)O_(2)(aq) to 2Mn^(2+)(aq)+8H_(2)O(l)+5O_(2)(g)`
(iii) `" " CaO(s)+H_(2)O(g) to Ca(OH)_(2)(s)`
(iv) `" " AlCl_(3)(g)+3H_(2)O(l) to Al(OH)_(3)(s)+3HCl(l)`
(v) `" " Ca_(3)N_(2)(s)+6H_(2)O(l) to 3Ca(OH)_(2)(s)+2NH_(3)(g).`
