Answer #1

1) In the shorthand notation for a galvanic cell, a double vertical line (II) represents a salt bridge (option D)

2)Shorthand notation that represents the following galvanic cell reaction Fe(s) + Cu2+ (aq) → Fe2+ (aq) + Cu(s) is

A. Fe(s) I Fe2+ (aq) II Cu2+ (aq) I Cu(s)

In tthe above reaction Fe(s) is getting oxidized to Fe2+(aq) while Cu2+(aq) is getting reduced to Cu(s). In Galvanic cell shorthand notation oxidation half is written on the left while reduction half on the right separated by vertical line (II) .
