Question:

Balance the following equations by the half-reaction method.

a. \(\mathrm{Fe}(s)+\mathrm{HCl}(a q) \longrightarrow \mathrm{HFeCl}_{4}(a q)+\mathrm{H}_{2}(g)\)

b. \(\mathrm{IO}_{3}{ }^{-}(a q)+\mathrm{I}^{-}(a q) \xrightarrow{\text { Acidic }} \mathrm{I}_{3}{ }^{-}(a q)\)

c. \(\mathrm{Cr}(\mathrm{NCS})_{6}{ }^{4-}(a q)+\mathrm{Ce}^{4+}(a q)\)

\[\xrightarrow{\text { Acidic }} \mathrm{Cr}^{3+}(a q)+\mathrm{Ce}^{3+}(a q)+\mathrm{NO}_{3}^{-}(a q)\]

\[+\mathrm{CO}_{2}(g)+\mathrm{SO}_{4}^{2-}(a q)\]

d. \(\mathrm{CrI}_{3}(s)+\mathrm{Cl}_{2}(g)\)

\[\xrightarrow{\text { Basic }} \mathrm{CrO}_{4}{ }^{2-}(a q)+\mathrm{IO}_{4}{ }^{-}(a q)+\mathrm{Cl}^{-}(a q)\]

e. \(\mathrm{Fe}(\mathrm{CN})_{6}{ }^{4-}(a q)+\mathrm{Ce}^{4+}(a q)\)

\[\begin{aligned}\stackrel{\text { Basic }}{\longrightarrow} & \mathrm{Ce}(\mathrm{OH})_{3}(s)+\mathrm{Fe}(\mathrm{OH})_{3}(s)+\mathrm{CO}_{3}{ }^{2-}(a q) \\& +\mathrm{NO}_{3}{ }^{-}(a q)\end{aligned}\]
