Question

Balance the following equations by ion electron method:
a. `CuO + NH_(3) rarr Cu+H_(2)O+N_(2)`
b. `HNO_(3)+I_(2) rarr HIO_(3) + NO_(2) + H_(2)O`

Answer 1

Correct Answer - A
a. `3CuO+2NH_(3)rarr3Cu+N_(2)+3H_(2)O`
b. `10 NO_(3)^(ө)+10H^(o+)+I_(2)rarr2IO_(3)^(ө)+2H^(o+)+2H^(o+)+10NO_(2)+4H_(2)O`
or
`10 HNO_(3)+I_(2)rarr2HIO_(3)+10NO_(2)+4H_(2)`
