For each of the following redox reactions, determine which element is being reduced and which is being oxidized. (help it should be a one element answer!!) (a) MnO2(aq) + K2C2O4(aq) + 2 H2SO4(aq) → MnSO4(aq) + K2SO4(aq) + 2 CO2(g) + 2 H2O(l) element being reduced : Mn Correct: Your answer is correct. element being oxidized: ?? (c) 2 CrO3(aq) + 3 CH3CH2OH(aq) → Cr2O3(aq) + 3 CH3CHO(aq) + 3 H2O(l) element being reduced ?? element being oxidized ??
