PART 2: Answer what is asked for each problem and show your solution. Round your answers
to four decimal places and they must be enclosed all in a box.
2. A chromium metal was deposited coming from a solution of Cr. The amount of the said
metal deposited weighs 2.19 g. The process is made possible through a current of 35.2
Amperes in electrolyte cell. Determine the following:
a. How much charge (in C) is required?
b. How long (in min) would it take for the reaction to occur?
3. Determine the molecular mass and identity of a +2 metal. X. that plates 46.3g of X in 6.75
hours at a current of 2 A.
4. Consider the voltaic cel which is based on the cell reaction:
Zn + Cua) - Zn + Cu
Under standard conditions, what is the maximum electrical work, in joules, that the cell can
accomplish if 50.0 g of copper is formed?
