Vedclass · Answer

(A) The reactions are as follows:$(A)$ $3Cu + 8HNO_3 	ext{ (dil)} ightarrow 3Cu(NO_3)_2 + 2NO + 4H_2O$. Products are $NO$ $(p)$ and $Cu(NO_3)_2$ $(s)$.$(B)$ $Cu + 4HNO_3 	ext{ (conc)} ightarrow Cu(NO_3)_2 + 2NO_2 + 2H_2O$. Products are $NO_2$ $(q)$ and $Cu(NO_3)_2$ $(s)$.$(C)$ $4Zn + 10HNO_3 	ext{ (dil)} ightarrow 4Zn(NO_3)_2 + N_2O + 5H_2O$. Products are $N_2O$ $(r)$ and $Zn(NO_3)_2$ $(t)$.$(D)$ $Zn + 4HNO_3 	ext{ (conc)} ightarrow Zn(NO_3)_2 + 2NO_2 + 2H_2O$. Products are $NO_2$ $(q)$ and $Zn(NO_3)_2$ $(t)$.Thus,the correct matching is $A-p, s; B-q, s; C-r, t; D-q, t$.

Column $I$	Column $II$
$(A)$ $Cu + \text{dil } HNO_3$	$(p)$ $NO$
$(B)$ $Cu + \text{conc } HNO_3$	$(q)$ $NO_2$
$(C)$ $Zn + \text{dil } HNO_3$	$(r)$ $N_2O$
$(D)$ $Zn + \text{conc } HNO_3$	$(s)$ $Cu(NO_3)_2$
	$(t)$ $Zn(NO_3)_2$
