Sun May 3 G 24%I Exam4.pdf (A) Mg or Cu (B) Fe or Z O Ag or PD 11. If a 2.5 A current flows through a circuit for 40 s, how many coulombs of charge moved through the circuit? 12. Consider two processes: sublimation of I2(s) and melting of I2(s) at the same temperature (Note: the latter process can occur at the same temperature but somewhat higher pressure). (A) I2(S)→I2(g) and (B) I2(S)¬I2(1) Is AS positive or negative in these processes? In which of the processes will the magnitude of the entropy change be greater? An important source of copper is from the copper ore, chalcocite, a form of copper(I) sulfide. When heated, the CuzS decomposes to form copper and sulfur described by the following equation: Cu2S(s) →Cu(s) + S(s) (13) Determine AG° for the decomposition of Cu2S(s). (use data from Appendix G) gas yields sulfur dioxide as the only product. Write an
