Balance the following equation in acidic solution using the lowest possible integers and give the coefficient of H+. MnO4 (aq) + H₂C204(aq)→ Mn²+ (aq) + CO2(g) Answer: 6 Consider the reaction between sulfite and a metal anion, X², to form the metal, X, and thiosulfate: 2 X²-(aq) +2 SO3² + 3 H₂O(l) → 2X(s) + S₂03² (aq) + 6 OH- for which Eºcell = 0.74. Given that the Eºred for sulfite is -0.57 V, what is the value of Eºred for X? Answer; -1.31 Consider the Figure shown in which X represents Zn(s), T represents Co(s), and S is a solution that is 1.0 M in Co²+. The reduction potentials of Co²+ and Zn²+ are -0.27 V and -0.76 V, respectively. Balance the following equation in acidic solution using the lowest possible integers and give the coefficient of H+.
