Vedclass · Answer

(D) The balanced reactions are:$Zn + 2H_2SO_4 	ext{ (hot conc.)} ightarrow ZnSO_4 (G) + SO_2 (R) + 2H_2O (X)$$Zn + 2NaOH 	ext{ (conc.)} ightarrow Na_2ZnO_2 (T) + H_2 (Q)$$ZnSO_4 (G) + H_2S + 2NH_4OH ightarrow ZnS (Z) + 2H_2O (X) + (NH_4)_2SO_4 (Y)$Analysis of statements:$(1)$ In $Na_2ZnO_2$ $(T)$,the oxidation state of $Zn$ is $+2$,not $+1$. So,statement $(1)$ is incorrect.$(2)$ $Q$ is $H_2$. The bond order of $H_2$ is $1$. So,statement $(2)$ is correct.$(3)$ $Z$ is $ZnS$,which is white in colour. So,statement $(3)$ is correct.$(4)$ $R$ is $SO_2$. $SO_2$ has a bent or $V$-shaped geometry. So,statement $(4)$ is correct.Thus,statements $(2, 3, 4)$ are correct.
