Data Reduction and Analysis The Copper Cycle Mindy McDuffie, Allan Ready, and Ms. Hye Jin Chun (T.A.) 1. Balance the molecular equations for each of the steps in the copper cycle. Cu (s) + HNO 3 (aq) Cu(NO 3 ) 2 (aq) + NO 2 (g) + H 2 0 (l) Cu(NO 3 ) 2 (aq) + NaOH (aq) Cu(OH) 2 (s) + NaNO 3 Cu(OH) 2 (s) CuO (s) + H 2 0 (l) CuO (s) + H 2 SO 4 (aq) CuSO 4 (aq) + H 2 0 (l) CuSO 4 (aq) + Zn (s) Cu (s) + ZnSO 4 (aq) 2. Write the net ionic equation for each of the 5 molecular equations. Cu (s) + HNO 3 (aq) Cu(NO 3 ) 2 (aq) + NO 2 (g) + H 2 0 (l)

Cu (s) + HNO 3 (aq) Cu(NO 3 ) 2 (aq) + NO 2 (g) + H 2 0 (l) Cu(NO 3 ) 2 (aq) + NaOH (aq) Cu(OH) 2 (s) + NaNO 3 Cu(OH) 2 (s) CuO (s) + H 2 0 (l) CuO (s) + H 2 SO 4 (aq) CuSO 4 (aq) + H 2 0 (l) CuSO 4 (aq) + Zn (s) Cu (s) + ZnSO 4 (aq) 4. Calculate the percent of copper, the mass of the recovered material. Assuimng that it is Cu, calculate the percent yield for the overall reaction. Discussion Question 5. Recreate the copper cycle as shown on page 33 pictorially to include more scientific and observational data. Artistic and aesthetic quality must match scientific rigor. How much information can you easily communicate?...
