For the reaction 2co3+(aq)+2cl? (aq)? 2co2+(aq)+cl2(g). e? =0.483 v what is the cell potential at 25 ? c if the concentrations are [co3+]= 0.719 m , [co2+]= 0.105 m , and [cl? ]= 0.387 m , and the pressure of cl2 is pcl2= 2.20 atm ? express your answer with the appropriate units.

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
