1. The problem statement, all variables and given/known data How many electrons are transferred in the following reaction? 6 Br^- (aq) + Cr2O7^2- (aq) + 14 H^+ --> 2Cr^3+ (aq) + 7H2O + 3Br2 (l) a) 1 b) 2 c) 3 d) 6 e) 14 2. Relevant equations 3. The attempt at a solution Redox reactions really confuse me, but I gave it a shot. I took a look at the number of electrons on each side of the equation and found the following: Left side: 6Br^- = -6 Cr2O7^2- = -2 14 H^+ = +14 Total: +6 Right side: 2Cr^3+ = +6 7H2O = 0 3 Br2 = 0 Total: 6 But this is as far as I can get. Somehow I don't think the answer is D) 6, but I really don't know. Someone please help me understand this problem?
