1. Calculate Ecell at 298 K for a cell involving Sn and Cu and their ions:
Sn(s) I│ Sn2+ (aq, 0.25 M) ││ Cu2+ (aq, 0.10 M) I Cu(s)
(a) 0.47 V
(c) 0.50 V
Answer: (a) 0.47 V
2. This week discussion forum is about the transition elements. Please refer to the periodic table link below to pick one of the transition element and talk about the element's physical, chemical properties, preparation, discovery, and industrial application of that element. Your assay should be no more than 200 words.
