I understand how to work with the other redox reactions I've runinto (we started doing these just over a week ago), but I can'tfigure out what to do when I see the same items in the oxidationAND reduction half reactions. Here are a few of the problems I'mhaving trouble solving. Please let me know how I can work my waythrough them.
1. Balance the following reaction, which takes place in anacidic solution.
Aqueous K2Cr2O7 + aqueous HCl = aqueous KCl + aqueous CrCl3 + H2O +gaseous Cl2
2. Use the same instructions as number 1.
Aqueous K2Cr2O7 + aqueous SnCl2 + aqueous HCl = aqueous CrCl3 +aqueous SnCl4 + aqueous KCl + H2O
3. Using half reactions, balance the following reaction, whichtakes place in an acidic solution
Aqueous KOH + solid MnO2 + solid S = H2O + aqueous KMnO4 + aqueousK2S
