Answers:SO32- + H2O = SO42- + 2 H+ + 2e- Cl2 + 2e- = 2 Cl- SO32- + Cl2 + H2O = SO42- + 2 Cl- + 2 H+ 2 IO3- + 12 H+ + 10e- = I2 + 6 H2O 2 I- = I2 + 2e- ) x 5 2 IO3- + 12 H+ + 10 I- = 6 I2 + 6 H2O divide by 2 IO3- + 6 H+ + 5 I- = 3 I2 + 3 H2O

Question:FeS + NO3- = Fe3+ + NO2 + S (please show work)

Answers:oxidation half reactions : Fe2+ = Fe3+ + 1e- S2- = S + 2e- reduction half reaction NO3- + 2 H+ + 1e- = NO2 + H2O ) x 3 3 NO3- + 6 H+ + 3 e- = 3 NO2 + 3 H2O Fe2+ = Fe3+ + 1e- S2- = S + 2e- ---------------------------------------------------------- 3 NO3- + 6 H+ + Fe2+ + S2- = 3 NO2 + Fe3+ + S + 3 H2O 3 NO3- + FeS + 6 H+ = Fe3+ + 3 NO2 + S + 3 H2O in acidic solution add 6 OH- on the left and on the right side ( 6 H+ + 6 OH- = 6 H2O) 3 NO3- + FeS + 3 H2O = Fe3+ + 3 NO2 + S + 6 OH- in alkaline solution

Question:In acidic solution, bromate ion can be used to react with a number of metal ions. One such reaction is BrO_3^{-}(aq) + Sn^2+(aq) --> Br^-(aq) + Sn^4+(aq) Since this reaction takes place in acidic solution, H_2O(l) and H^+(aq) will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation: BrO_3^-(aq) + Sn^2+(aq) + _____ --> Br^-(aq) + Sn^4+(aq) + _____ QUESTION: What are the coeffcients for the six species including H2O and H?

Answers:For every O, add one H2O on the opposite side... THEN for every H, add one H+ on the opposite side.
