Match each of the reactions given in Column - I with the corresponding product(s) given in Column - II:
Column−IColumn−II(a) Cu+dil.HNO3(p) NO(b) Cu+conc.HNO3(q) NO2(c) Zn+dil.HNO3(r) N2O(d) Zn+conc.HNO3(s) Cu(NO3)2(t) Zn(NO3)2
(a) → (p,s); (b) → (q,s); (c) → (r, t); (d) → (q,t)
3Cu+(dil.)8HNO3→3Cu(NO3)2+2NO+4H2O
3Cu+(conc.)4HNO3→Cu(NO3)2+2NO2+2H2O
4Zn+(dil.)10HNO3→4Zn(NO3)2+N2O+5H2O
Zn+(conc.)4HNO3→Zn(NO3)2+NO2+2NO2
