One mole of N(2)H(4) loses ten moles of ...

One mole of `N_(2)H_(4)` loses ten moles of electrons of 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 state of hydrogen.)

Text Solution

Verified by Experts

`N_(2)H_(4) to (Y)+10e^(-)`
Y contains all N-atoms
`N_(2)^(2-) to (2N)^(a)+10e^(-)`
Therefore, 2a-(-4) =10 `rArr a=+3`
