Name the reducing agent in the following reaction:
3MnO2 + 4Al———— > 3Mn + 2Al2O3
State which is more reactive, Mn or A1 and why?

MnO2 is oxidising agent, because it looses Oxygen in this reaction. Al is reducing reagent because it accepts oxygen.
According to reactivity series, Aluminium is more reactive than magansese.
