thàn 7.0? Justify your answer. prr greatci or TesS 9. Assuming the schematics below represent galvanic cells as written, identify the half-cel reactions occurring in each. (A) Mg(s)| Mg*(aq) || Cu²*(aq)| Cu(s) 2+ 2+ (B) Ni(s) Ni*(aq) || Ag*(aq)| Ag(s) 2+ 10. Which member of each pair of metals is more likely to corrode (oxidize)? (A) Mg or Cu (B) Fe or Zn (C) Ag or Pb 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)→L(1) Is AS positive or negative in these processes? In which of the processes will the magnitude of entropy change be greater?
