Question

name the oxidizing agent and reducing in the following reaction:-CuO +H2 - Cu + H
2O

Answer 1

cuo gets reducing and

and H

Answer 2

:Cu (s) + 2 NO3− (aq) + 4 H+ (aq) + 4 H2O (l) →  [Cu(H2O)6]2+ (aq) + 2 NO2 (g)

B:  [Cu(H2O)6]2+ (aq) + 2 OH- (aq) → Cu(OH)2 (s) + 6 H2O (l)

C:  Cu(OH)2 (s) → CuO (s) + H2O (l)

D:  CuO (s) + 2 H+ (aq) + 5 H2O (l) → [Cu(H2O)6]2+ (aq)

E:  [Cu(H2O)6]2+ (aq) + Zn (s) → Cu (s) + Zn2+ (aq) + 6 H2O (l)
