6. Copper(1) iodide, Cul, is not stable enough to last long in storage, so it is generally made just prior to use. In can be prepared from copper sulphate and hydriodic acid by the following reaction: 2 Cuso,(s) + 4 HI(aq) - a) If 10.4 grams of CuSO, is used, calculate the number of grams of HI needed and the ---> 2 Cul(s) + 2 H,So,(aq) + L,(s) number of grams of each of the products that are produced. Show that the mass data are in accordance with the law of conservation of mass in chemical reactions. b) If 10.4 grams of copper(I) iodide were isolated from the reaction above, what is the percent yield of the reaction?
