Galvanic cell runs on the following reaction: al (s) + fe3+ (aq) → al3+ (aq) + fe (s) draw a diagram for this galvanic cell, labeling the electron flow, the anode and cathode, and the positive and negative sides of the galvanic cell. answer only if you know show the diagram ! i don't understand

See image for details.

The answer is probably c. xylem

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
