Given $: \frac{2.303 RT }{ F }=0.06 V$
$Pd _{( aq )}^{2+}+2 e ^{-} \rightleftharpoons Pd ( s ) \quad E ^{\circ}=0.83\,V$
$PdCl _4^{2-}( aq )+2 e ^{-} \rightleftharpoons Pd ( s )+4 Cl ^{-}( aq )$
$E ^{\circ}=0.65\,V$
$Fe ^{2+}( aq )+ S ^{2-}( aq ) \rightleftharpoons FeS ( s )$
When equal volumes of $0.06 M Fe ^{2+}( aq )$ and $0.2 M S ^{2-}( aq )$ solutions are mixed, the equilibrium concentration of $Fe ^{2+}$ (aq) is found to be $Y \times 10^{-17} M$. The value of $Y$ is. . . . .

$(2)$ $NaN{H_2};C{H_3}C{H_2}C{H_2}Br$:${H_2}{\text{ (two moles) }}Pd{\text{ or }}Ni$
$(3)$ $NaN{H_2};C{H_3}C{H_2}C{H_2}Br$:${H_2},{\text{ (one mole) }}Pd{\text{ or }}Ni$
$(4)$ $NaN{H_2};C{H_3}C{H_2}C{H_2}Br$:$B{H_3},{H_2}{O_2},O{H^ - }$
$O(g) + e^- \to O^-(g); \Delta H = - 142 \,kJ \,mol^{-1}$
$O^-(g) + e \to O^{2-} (g); \Delta H = 844\, kJ \,mol^{-1}$
This is because
Acidified $K _2 Cr _2 O _7$, alkaline $KMnO _4, CuSO _4, H _2 O _2, Cl _2, O _3, FeCl _3, HNO _3$ and $Na _2 S _2 O _3$. The total number of reagents that can oxidise aqueous iodide to iodine is
