A mole of `N_(2)H_(4)` loses 10 mol of electrons to form a new compound Y. Assuming that all the nitrogen appears in the new compound, what is the oxidation state of nitrogen in Y ? ( There is no change in the oxidation number of hydrogen. )

A

`+1`

B

`-3`

C

`+3`

D

`+5`

Verified by Experts

The correct Answer is:
C
`undersetunderset(2x=-4)(2x+4=0)(N_(2)H_(4)tounderset((2y))(2N)+10e^(-)`
`underset(y=3)(because2y-(-4)=10)`
