For each of the following reactions, balance the chemical equation, calculate the emf, and calculate Delta G degree at 298 K. (Use the smallest possible coefficients for H_2O(l), H^+(aq), and HO^- (aq). These may be zero.) Aqueous iodide ion is oxidized to I_2(s) by Hg_2^2+(aq). I^- (aq) + 1 Hg_2^2+(ag) + H^+ rightarrow I_2(s) Hg(I) + H_2O(l) emf V Delta G degree kJ In acidic solution copper(I) ion is oxidized to copper(II) ion by nitrate ion. Cu^+(aq) + NO_3^- (ag) + H^+(aq) rightarrow Cu^2+(aq) NO(g) + H_2O(l) emf V Delta G degree kJ In basic solution Cr(OH)_3(s) is oxidized to CrO_4^2- (aq) by CIO^- (aq). Cr(OH)_3(s) + CIO^- (aq) + OH^- (aq) rightarrow CrO_4^2- (aq) Cl^- (aq) + H_2O(l) emf V Delta G degree kJ
