The voltage of a galvanic cell made with magnesium (Mg) and gold (Au) can be calculated using their standard reduction potentials. Magnesium has a standard reduction potential of about -2.37 V, while gold has a standard reduction potential of +1.50 V. The overall cell potential can be calculated by subtracting the reduction potential of magnesium from that of gold, resulting in a voltage of approximately +3.87 V. This indicates that the galvanic cell can produce a significant amount of electrical energy.
The voltage of a galvanic cell made with magnesium (Mg) as the anode and gold (Au) as the cathode can be estimated using standard reduction potentials. Magnesium has a standard reduction potential of -2.37 V, while gold has a standard reduction potential of +1.50 V. The overall cell potential can be calculated by subtracting the anode potential from the cathode potential, resulting in a voltage of approximately +3.87 V for the cell. This positive voltage indicates that the cell can generate electrical energy.
The standard cell notation for a galvanic cell made with magnesium (Mg) and gold (Au) can be represented as: Mg(s) | Mg²⁺(aq) || Au³⁺(aq) | Au(s). In this notation, magnesium is the anode (oxidation occurs) and gold is the cathode (reduction occurs), with the vertical bars separating different phases and the double vertical bar indicating the salt bridge.

The standard cell notation for a galvanic cell made with magnesium (Mg) and gold (Au) can be represented as: Mg(s) | Mg²⁺(aq) || Au³⁺(aq) | Au(s). In this notation, magnesium is the anode (oxidation occurs) and gold is the cathode (reduction occurs), with the vertical bars separating different phases and the double vertical bar indicating the salt bridge.
The stranded cell notation for a galvanic cell made with magnesium (Mg) and gold (Au) is written as: [ \text{Mg(s)} | \text{Mg}^{2+}(aq) || \text{Au}^{3+}(aq) | \text{Au(s)} ] In this notation, the anode (Mg) is on the left side, while the cathode (Au) is on the right, with a double vertical line (||) representing the salt bridge that separates the two half-cells.
