Using the two cell reduction potentials shown for their corresponding reaction, calculate the cell potential for a voltaic cell made from these two systems. (HELP ASAAAP) A)

1.68 V

B)

0.78 V

C)

–1.68 V

D)

–0.78 V

multiply the first equation by 3 to cancel the electrons in both equations

then combine both equations

then minus both cell potentials which equals 0.78 V

I'm not sure though

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
