Yes. the molecular weight of magnesium is 24.3 g/mol and gold is 197
Gold is preferred for jewelry over iron and magnesium because it does not tarnish, corrode, or rust. Gold is also more malleable and can be easily shaped into intricate designs, making it a popular choice for fine jewelry. Additionally, gold's rarity and luster give it a sense of luxury and value that iron and magnesium do not possess.
Gold potassium cyanide is typically produced by electrolyzing a gold cyanide solution, where gold is electroplated onto a cathode. This process involves using a soluble anode made of gold and a cathode made of stainless steel or titanium. The electrolysis takes place in a specially designed cell containing the gold cyanide solution and requires strict control of parameters such as temperature, current density, and pH to ensure high-quality product formation. After the electrolysis is complete, the gold potassium cyanide is usually purified and then dried to obtain the final product.
Gold is a precious metal known for its luster and malleability, iron is a common element used in construction and manufacturing, and magnesium is a lightweight metal used in alloys and as a dietary supplement.

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.
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 standard cell notation for a galvanic cell with aluminum and gold electrodes is represented as: Al(s) | Al³⁺(aq) || Au³⁺(aq) | Au(s). In this notation, the anode (aluminum) is listed on the left, and the cathode (gold) is on the right. The double vertical line (||) indicates the salt bridge or separation between the two half-cells. The state of each component (solid or aqueous) is also noted.
Gold is reduced. Gold is plated onto the cathode.
