Unless noted, be sure to indicate how many significant figures your answer should be reported to. The use of any calculator except your brain or fingers and toes is not permitted. 1. Sodium dichromate reacts with copper in acidic solution as follows (MW's are under each): Na2Cr207 + 3 Cu + 14 HCI 2 CrCl3 + 3 CuCl2 + 7 H2O 221.98 63.55 36.46 158.33 134.45 18.02 Part A) The reaction of 525 mL of 0.450 M HCI in the presence of excess copper and excess sodium dichromate can produce how many grams of copper (II) chloride? Part B) The reaction 50.00 mL of 0.1234 M HCI in the presence of excess sodium chromate and Cu produced 2.3 g of chromium (III) chloride. Calculate the % yield for the reaction.
