Please don't provide handwritten solution solution ..... A rod of magnesium is typically placed in a water heater as a sacrificial anode. A certain magnesium anodehas a mass of 300 g. The current that develops between the water heater and the anode is 10mA. How manyyears will it take for the anode to completely corrode away?

The mass of magnesium metal = Current that develops = Use this data to calculate the time in years…

Answered: A rod of magnesium is typically placed…

The mass of three different metal electrodes, each from a different galvanic cell, were determined before and after the current generated by the oxidation-reduction reaction in each cell was allowed to flow for a few minutes. The first metal electrode, given the label A, was found to have increased in mass; the second metal electrode, given the label B, did not change in mass; and the third metal electrode, given the label C, was found to have lost mass. Make an educated guess as to which electrodes were active and which were inert electrodes, and which were anode(s) and which were the cathode(s).
An aqueous solution of an unknown salt of gold is electrolyzed by a current of 2.75 amps for 3.39 hours. The electroplating is carried out with an efficiency of 93.0%, resulting in a deposit of 21.221 g of gold. a How many faradays are required to deposit the gold? b What is the charge on the gold ions (based on your calculations)?
the electroplating of a silver spoon, the spoon acts as thecathode and a piece of pure silver as the anode. Both dipinto a solution of silver cyanide (AgCN). Suppose that acurrent of 1.5 A is passed through such a cell for 22 minutesand that the spoon has a surface area of 16cm2. Calculatethe average thickness of the silver layer deposited onthe spoon, taking the density of silver to be 10.5gcm3.
