1 mol of N2 H4 loses 10 mol of electrons to form a new compound X. Assuming that all the nitrogen appears in the new compound and no change in the oxidation state of hydrogen, the oxidation number in X is
With the loss of 10mol of electrons, the increase in O.N. of 2 N-atoms = 10. If x is the O.N. of M in the new compound, then
