Tommy Trojan and Thomasina Trojan are both analyzing the same hydrogen peroxide solution by the method of Experiment #9. Tommy used 1.5 g of the potassium iodide while Thomasina only used 0.5 g. Which of the following statements is true? a.The amount of oxygen produced by Tommy is three times that produced by Thomasina. b.The amount of oxygen produced by Tommy is one-third that of Thomasina. c.The amount of oxygen produced by Thomasina is one-third of the amount produced by Tommy. d. The amount of oxygen produced by Thomasina is equal to the amount of oxygen produced by Tommy. e.The ratio of the amount of oxygen produced by Tommy to that produced by Thomasina is the reciprocal of the ratio of the mass of potassium iodide used.
