Lean 1 Learning Objective: 7J Distinguish between actual and theoretical yield to calculate percent yield Question A0.156 g piece of solid aluminum reacts with gaseous oxygen from the atmosphere to form solid aluminum oxide. In the laboratory, a student weighs the mass of the aluminum oxide collected from this reaction as 0.1798- 1st attempt Part 1 See Periodic Table The 0.156 g solid aluminum is the Choose one: A theoretical yield B. excess reagent C. percent yield D. actual yield E limiting reagent

Part 2 The 0.179 g aluminum oxide is the Choose one: A. excess reagent OB. actual yield C. theoretical yield D. limiting reagent E percent yield Part 3 The gaseous oxygen is the Choose one: A. excess reagent B. percent yield C. theoretical yield D. actual yield E limiting reagent

Part 3 The gaseous oxygen is the Choose one: O A. excess reagent B. percent yield C. theoretical yield O D. actual yield O E. limiting reagent Part 4 What is the percent yield of this reaction? MacBook Pro
