In a reduction reaction, some electrons are gained by the substance being reduced. The balanced half-reaction to this would be:

MnO2 (s) + 4 H + (aq) + 2e - - - > Mn^2 + (aq) + 2 H2O (aq)

It is called balanced reaction since the number of each element in the left side is equal to the number of each element on the right side.
