How many moles of electrons are required to reduce one mole of mno4- to one mole of mn2+? (2 points)

3 e-

4 e-

5 e-

6 e-

The answer would be 6 e-. This is becuase you are turning a charge of -4 into a +2. In order to do this, you transfer 4 electrons for a neutral charge, and an additional 2 for a charge of +2.

This makes a total charge of +2, and the total transferred electrons 6 e-

The kinetic energy of the liquid increases. hope this !

Idon't know hope someone you
