b) Balance the following chemical reaction, which was carried out in acidic medium. The redox reaction between Cr2O72- (aq) and C204² (aq) in acidic medium produces Cr³+ (aq) and CO₂(g). (i) The oxidizing agent is_ and the reducing agent is_ (ii) Write a balanced chemical equation for this reaction. (iii) When 50.00 mL of 0.1450 M Cr₂O7² (aq) was reacted with 36.25 mL of 0.2000 M C₂04² (aq) the amount of carbon dioxide gas collected was 8.118 x 1021 molecules. Calculate the percentage yield of carbon dioxide gas?
