Consider the following unbalanced equation.

H1+(aq) + Fe(s) H2(g) + Fe2+(aq)

What is the balanced oxidation half-reaction?
What is the balanced reduction half-reaction?
What is the balanced overall cell reaction?

1 answer

redn half equation is
2H^+ + 2e ==> H2
oxidation half equation is
Fe ==> Fe^2+ + 2e

2H^+ + Fe --> Fe^2+ + H2 is the total balanced equation.
