manganese dioxide and aluminimun powder:
3MnO2 + 4Al ----> 3Mn + 2Al2O3
Aluminium powder is a reducing agent. These displacement reactions are so exothermic that the metals are produced in the molten state.
manganese powder and aluminium oxide:
Mn + Al2O3 ---x--->
No reaction takes place here as Al is more reactive than manganese.
