Answer: Balance the following skeleton reactions and

Chapter 22, Problem 9P

(choose chapter or problem)

Balance the following skeleton reactions and identify the oxidizing and reducing agents:

(a) \(\mathrm{BH}_{4}{ }^{-}(a q)+\mathrm{ClO}_{3}{ }^{-}(a q) \longrightarrow\)

\(\mathrm{H}_{2} \mathrm{BO}_{3}^{-}(a q)+\mathrm{Cl}^{-}(a q)\) [basic]

(b) \(\mathrm{CrO}_{4}{ }^{2-}(a q)+\mathrm{N}_{2} \mathrm{O}(g) \longrightarrow \mathrm{Cr}^{3+}(a q)+\mathrm{NO}(g)\) [acidic]

(c) \(\mathrm{Br}_{2}(l) \longrightarrow \mathrm{BrO}_{3}{ }^{-}(a q)+\mathrm{Br}^{-}(a q)\) [basic]

BH_4^−(aq)+ClO_3^ −(aq) longrightarrow H_2 BO_3^−(aq)+Cl^−(aq)  

CrO_4^ 2−(aq)+N2O(g) longrightarrow Cr^3+(aq)+NO(g)  

Br_2(l) longrightarrow BrO_3^ −(aq)+Br^−(aq)
