Chapter 8, Problem 72

(choose chapter or problem)

Determine whether or not each reaction is a redox reaction. For each redox reaction, identify the oxidizing agent and the reducing agent.

a. \(\mathrm{Al}(\mathrm{s})+3 \mathrm{Ag}^{+}(a q) \longrightarrow \mathrm{Al}^{3+}(a q)+3 \mathrm{Ag}(\mathrm{s})\)

b. \(\mathrm{SO}_{3}(\mathrm{g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \longrightarrow \mathrm{H}_{2} \mathrm{SO}_{4}(a q)\)

c. \(\mathrm{Ba}(\mathrm{s})+\mathrm{Cl}_{2}(g) \longrightarrow \mathrm{BaCl}_{2}(s)\)

d. \(\mathrm{Mg}(\mathrm{s})+\mathrm{Br}_{2}(l) \longrightarrow \mathrm{MgBr}_{2}(\mathrm{s})\)
