The molarity of the Cu2+ and Zn2+ solutions used in the setup of the electrochemical cell was 1 M. Explain why the voltage was not equal to the standard reduction potential for the Cu Zn redox reaction at all times during the experiment.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
