In a galvanic cell, the less reactive metal is the cathode, where oxidation takes place. In this case the cathode is zinc.

No, the cathode is negative in a galvanic cell.
In a galvanic cell, the cathode is positive.
In a galvanic cell, the cathode is the positive electrode.
The anode is more prone to corrosion in a galvanic cell.

In a galvanic cell involving magnesium (Mg) and zinc (Zn), the cathode is the electrode where reduction occurs. In this case, zinc acts as the cathode because it has a higher reduction potential compared to magnesium. Therefore, zinc ions in solution gain electrons and are reduced to solid zinc at the cathode, while magnesium oxidizes at the anode.
No, the cathode is negative in a galvanic cell.
In a galvanic cell, the cathode is positive.
In a galvanic cell, the cathode is the positive electrode.

If steel is the cathode in a galvanic cell, then another metal must be the anode. The anode is where oxidation occurs, so a metal that oxidizes more readily than steel, such as zinc or magnesium, would likely be the anode in this scenario.
The anode is more prone to corrosion in a galvanic cell.
The reduction half-reaction of a redox reaction
A galvanic cell is a spontaneous reaction so electron flow will occur as long as a salt bridge is present.
The voltage of a galvanic cell can be calculated using the standard reduction potentials of the half-reactions involved. For a cell with copper (Cu) and magnesium (Mg), the standard reduction potential for Cu²⁺/Cu is +0.34 V, and for Mg²⁺/Mg, it is -2.37 V. The overall cell potential (E°cell) can be calculated as E°(cathode) - E°(anode), resulting in E°cell = 0.34 V - (-2.37 V) = 2.71 V. Therefore, the voltage of the galvanic cell with copper and magnesium is 2.71 V.
