Question

what type of electrochemical cell is described in this example? mg / mg²⁺ fe / fe²⁺ galvanic cell downs cell prokaryotic cell electrolytic cell

Explanation:

A galvanic cell (also called a voltaic cell) uses spontaneous redox reactions to generate an electric current. Here, Mg and Fe with their ions form a cell where a spontaneous reaction occurs (Mg is more reactive than Fe, so Mg will oxidize and Fe²⁺ will reduce). A Downs cell is for producing sodium metal, a prokaryotic cell is a type of biological cell, and an electrolytic cell uses non - spontaneous reactions with external energy. So the correct type is a galvanic cell.

Answer:

A. Galvanic Cell
