Calculate the corrosion rate of a copper wire of diameter 0.5 cm and length 20 cm when immersed in a solution containing 1M HCl for 24 hours. The initial and final weights of the wire were 6.0 g and 5.6 g, respectively. The density of copper is 8.96 g/cm³. What is the corrosion rate of the copper wire in mm/year?

A student wants to calculate the corrosion rate of a zinc electrode in contact with a copper electrode, with a measured current of 0.5 amperes and a surface area of 2 cm². Given that the standard reduction potentials for copper and zinc electrodes are +0.34 V and -0.76 V, respectively, what is the corrosion rate of the zinc electrode in millimeters per year? (Assume a density of 7.14 g/cm³ for zinc and a Faraday constant of 96,500 coulombs per mole).

A steel pipe is connected to a copper pipe in a galvanic corrosion couple where the electrolyte is seawater. The corrosion current density of the steel pipe is 3.2 mA/cm2. If the surface area of the steel pipe is 5 cm2, calculate the total amount of charge transferred per hour. Also, calculate the weight loss of the steel pipe per year due to galvanic corrosion, assuming the density of steel is 7.85 g/cm3.

A copper rod with a surface area of 5 cm² is coupled with an iron rod with a surface area of 10 cm² to form a galvanic cell. When the circuit is closed, the current flows for 2 hours and the weight loss of the iron rod was found to be 0.58 g. Determine the corrosion rate of the iron rod in millimeters per year (mm/yr) assuming a density of 7.86 g/cm³ for the iron.
