Question
A mole of N2H4 loses 10 mol of electrons to from 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.)
Options
A.-1
B.-3
C.+3
D.+5
Solution
N2H4 → 2y + 10e-
2x + 4 = 0 2y = 2x
2x = - 4
2x + 4 = 0 2y = 2x
2x = - 4
