A voltaic cell has Cu/Cu^2+ and Hg/Hg2^2+ half cells. E^o is +0.34 V for the reaction Cu^2+ +2 e- > Cu3 and Eo is +0.79 V for the reaction Hg2^2+ + 2e- > 2 Hg. Write the net reaction for this voltaic cell and calculate E^o for the cell. Use Proper significant figures and units.

i'm pretty sure its b i might be wrong though!

can you attach the

i don't know people like to fight everywhere rip.

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.
