Problem: What coefficient of H+ balances the atoms in this half-reaction?H+(aq) + MnO2(s) → Mn2+(aq) + H2O(l)

FREE Expert Solution

We are asked to only identify the coefficient of H+ balances the atoms in this half-reaction


Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.


Reaction 1:

H+(aq) + MnO2(s) → Mn2+(aq) + H2O(l)

Mn   1

H      1

O      2

Mn      1

H      2
