e. Cu 4. Mass of test tube + Cu recovered 1st mass (g) 2nd mass (g) 3rd mass (g) 5. Mass of Cu recovered 6. Percent Yield 7. Discuss the variance of your percent yield from the theoretical recovery. CONCLUSION QUESTIONS 1. Part A.2. What is the of NO2 gas? 2. Part B. What observation would indicate the loss of copper from the cycle? 3. Part E. Sulfuric acid has a dual role in the copper cycle of reactions. Identify each. 4. Part E.2. If sulfuric acid were unavailable to remove the unreacted magnesium from the mixture and nitric acid were used instead, what observations (if any) would occur in the experiment? 5. In Part E.3. a. Explain what factors may contribute to a greater than 100% recovery of copper in the cycle of chemical reactions.
