Question

Match the reactions in column I with the molar ratio of their respective oxidants and reductant in column II.

Answer 1

(A) For the reaction $H^{\oplus }+U{\left(S{O}_4\right)}_2+KMn{O}_4⟶U{O}_{2}S{O}_4+MnS{O}_4$
the molar ratio of oxidants and reductant is $\frac{2}{5}$.
(B) For the reaction $Cr{I}_3+{Cl}_2+\stackrel{\ominus }{O}H⟶Cr{O}_4^{2-}+I{O}_4^{\ominus }+{Cl}^{\ominus }$
the molar ratio of oxidants and reductant is $\frac{27}{2}$.
(C) For the reaction $HAs{O}_3^{2-}+Br{O}_3^{\ominus }+H^{\oplus }⟶H_{3}As{O}_4+{Br}^{\ominus }$
the molar ratio of oxidants and reductant is $\frac{1}{3}$.
(D) For the reaction $O_2+N{H}_3⟶NO+H_{2}O$
the molar ratio of oxidants and reductant is $\frac{5}{4}$.
(E) For the reaction ${Sb}_2{O}_3+I{O}_3^{\ominus }+H^{\oplus }⟶HSb{\left(OH\right)}_6+ICl$
the molar ratio of oxidants and reductant is $1$.
(F) For the reaction $W{O}_3+Sn{Cl}_2+H^{\oplus }⟶W_3{O}_8+Sn{Cl}_6^{2-}$
the molar ratio of oxidants and reductant is $3$.
