Balance the following electrochemical reaction in acid:
MnO4 − ( aq ) + Zr( s ) ↔ Mn2+( aq ) + Zr2+( aq )
A) 2 MnO4 − ( aq ) + 16H+( aq ) + 5 Zr( s ) → 2 Mn2+( aq ) + 5 Zr2+( aq ) + 8 H2O( l )
B) 2 MnO4 − ( aq ) + 5 Zr( s ) → 2 Mn2+( aq ) + 5 Zr2+( aq )
C) MnO4 − ( aq ) + Zr( s ) → Mn2+( aq ) + Zr2+( aq ) + 5 e −
D) 2 MnO4 − ( aq ) + 8H+( aq ) + 5 Zr( s ) → 2 Mn2+( aq ) + 5 Zr2+( aq ) + 8 H2O( l )
