Question

In the reaction

3CuO + 2NH₃ → N₂ + 3H₂O + 3Cu

the change of NH₃ to N₂ involve …………

(A) loss of 6 electrons per mol of N₂

(B) loss of 3 electrons per mol of N₂

(C) gain of 6 electrons per mole N₂

(D) gain of 3 electrons per mole N₂

Answer 1

Correct option is: (A) loss of 6 electrons per mole of N₂

Thus, there is loss of 6 electrons per mole of \(N_2\) or there is gain of 2 electrons per mole of Cu.

Answer 2

(A) loss of 6 electrons per mol of N₂
