3 MnO subscript 2 space plus space 4 space Al space rightwards arrow 3 Mn space plus space 2 Al subscript 2 straight O subscript 3
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.
