Question

please help with these, the standard reduction potentials are given in the last two pictures

A standard galvanic cell is constructed in which a Cu2+ Cu half cell acts as the cathode. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) The cathode reaction is Cu -> Cu2+ + 2e Fe2+Fe could be the other standard half cell. Hg2+Hg could be the other standard half cell. In the external circuit, electrons flow from the other compartment to the CuCu compartment. The anode reaction could be Fe -> Fe2+ + 2e"

Answer 1
