Copper metal can be produced from a solution containing copper sulphate by passing the solution ver a vat containing iron metal scraps. Write the half-cell and the overall reaction equations of the process. If the copper is produced by hydrogen reduction, write the appropriate reaction equations and sketch the precipitation window for the process. (log KCu = 11.44; log KH2 = 0)

A certain half-reaction has a standard reduction potential E = -0.23 V. An engineer proposes using this half-reaction at the anode of a red galvanic cell that must provide at least 0.60 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction. potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box. By using the information in the ALEKS Data tab, write a balanced equation describing a half reaction that could be used…

A certain metal M forms a soluble nitrate salt MNO3. Suppose the left half cell of a galvanic cell apparatus is filled with a 175. mM solution of MNO3 and the right half cell with a 3.50 M solution of the same substance. Electrodes made of M are dipped into both solutions and a voltmeter is connected between them. The temperature of the apparatus is held constant at 35.0 °C. Which electrode will be positive? What voltage will the voltmeter show? Assume its positive lead is connected to the positive electrode. 0 Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits. left right ■ □x10 X S
