Balance the subsequent equations in both acidic and basic environments Show the half reactions right before they are added together after balancing all the components and then show the balanced equation:
1) Cr2O72-(aq) + C2H5OH(l) --> Cn3+(aq) + CO2(g)
2) Fe2+(aq) + MnO4-(aq) --> Fe3+(aq) + Mn2+(aq)
