Expert Solution

Mn + Al^+3-----> Mn^+2 + Al

oxidation half reaction                                                                             reduction half reaction

Mn ----------------> Mn^2+ + 2e^-                                                            Al^3+ + 3e^- ---------------> Al

3Mn ----------------> 3Mn^2+ + 6e^-                                                      2Al^3+ + 6e^- ---------------> 2Al

                                                      3Mn ----------------> 3Mn^2+ + 6e^-

                                                      2Al^3+ + 6e^- ---------------> 2Al

                                                     ---------------------------------------------------

                                               3Mn + 2Al^3+ ---------------------> 3Mn^2+ + 2Al
