Which half reaction occurs at the cathode in this cell? o 2003-> O2 + 2002 +4e-
O O2 + 200, +4e-
> 2003
2H2 + 2003- -
2H2O + 200, +4e
2H20 + 200, +4e--> 2H2 + 2003-

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

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
