Magnesium can be acquired by the electrolysis of molten MgCl₂. Calculate the required current to acquire 650 g of Mg in a span of 2 hours.

An aqueous metal nitrate [M(NO3)₃] solution was subjected to electrolysis using a current of 25.0 A. If 408 g of the metal is produced in 400 min, what is the identity of the metal ion (M³⁺)?

How many kilowatt-hours of electricity are needed to obtain 1.0×10³ kg (1 metric ton) of chromium through the electrolysis of Cr³⁺, given that this process has a 40% efficiency and the applied voltage is 5.10 V?  

Which of the following best explains how galvanizing prevents or minimizes rusting of steel?

When the current is passed through an HCl solution, bubbles come out of the solution as H⁺ becomes H₂ gas. Determine the pH of a 4.18 L and 0.378 M HCl solution after passing through 27.5 A for 39 minutes.

A sodium/nickel chloride battery operates at a temperature range of 270°C-350°C using molten metals and salts. Sodium acts as the anode and nickel acts as the cathode. A beta-alumina ceramic wall serves as a barrier between the electrodes which is conductive for sodium ions but not for electrons. The cell has a voltage of overall cell reaction is 2.58 V and the cell reaction is as follows:

Na(s) | Na(sol'n), NaCl(soln) || Ni(sol'n), NiCl₂(sol'n) | Ni(s)

Calculate the mass of nickel produced (in kilograms) if a 12.3 kW sodium/nickel chloride battery produces a current in a span of 45.0 minutes.

Calculate the time (in hours) it will take to produce 1.50×10³ kg of potassium when a sample of molten KF was subject to electrolysis using a constant current of 2.50×10⁴ A. Determine the volume (in L) of F₂ gas produced at STP.
