Question

One mole of N2H4 loses 10 moles of electrons to form a new compound y. Assuming that all nitrogen appears in the new compound, what is the oxidation state of nitrogen in y.

a. -1

b. -3

c. +3

d. +5​

Answer 1

Answer:

1 mole N2H4 loses 10mole e-

So, 1 N2H4 loses 10e-

So, new compound Y=(N2H4)10+

Charge on y is 10+

Let charge on N be x.

2x+4=10

x=+3
