Question 1

A copper electrode weighs 35.42 g before the electrolysis of a copper (II) sulfate solution and 36.69 g after the electrolysis has run for 20.0 s. What was the amperage of the current used?
◦ 2.12 A
◦ 0.0335 A
◦ 48.2 A
◦ 96.4 A
◦ 193 A

Question 2

A galvanic cell consists of a Ni^²+(aq)/Ni(s) half-cell and a standard hydrogen electrode. If the Ni^²+/Ni half-cell standard cell functions as the anode, and the standard cell potential is 0.26 V, what is the standard reduction potential for the Ni^²+(aq)/Ni(s) half-cell?
◦ -0.26 V
◦ -0.13 V
◦ +0.13 V
◦ +0.26 V
