For bromine, Delta H_vap = 30.91 kJ/mol and Delta S_Vap = 93.23 JK^-1 mol^-1. What is the normal boiling point for bromine? A)58 degree C B)124 degree C C)25 degree C D)332 degree C For which process(es) will the entropy of the system decrease? A 100 gram sample of Cu is heated from 275 K to 295 K. AgCl(s) is dissolved in aqueous ammonia. Compressing one mole of Ne gas at a constant temperature PCl_3 (l) + Cl_2 (g) rightarrow PCl_5 (s) CO_2(g) + 2H_2 O(l) rightarrow CH_3 OH(g) + 1.5 O_2(g) A) 1 and 3 B) 3 and 4 C) 2 and 5 D) 4 and 5 E) 1 and 2
