Question

Balance the following redox reactions. It is recommended that you use balanced half reactions to proceed: \text { (a) } \mathrm{KMnO}_{4}+\mathrm{Fe} \mathrm{SO}_{4}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{Fe}^{3+}+\mathrm{K}_{2} \mathrm{SO}_{4}+\mathrm{MnSO}_{4}+\mathrm{H}_{2} \mathrm{O} \text { (b) } \mathrm{HClO} \rightarrow \mathrm{HClO}_{3}+\mathrm{HCl} \text { (c) } \mathrm{NO}_{2}^{-}+\mathrm{MnO}_{4}^{-}+\mathrm{H}^{+} \rightarrow \mathrm{NO}_{3}^{-}+\mathrm{Mn}^{2+}+\mathrm{H}_{2} \mathrm{O} \text { (d) } \mathrm{Cl}+\mathrm{NO}_{3}^{-}+\mathrm{H}^{+} \rightarrow \mathrm{Cl}_{2}+\mathrm{NO}+\mathrm{H}_{2} \mathrm{O} \text { (e) } \mathrm{l}_{2}+\mathrm{IO}_{3}^{-}+\mathrm{H}^{+}+\mathrm{Cl} \rightarrow \mathrm{ICl}_{2}^{-}+\mathrm{H}_{2} \mathrm{O}
