The following reaction takes place when the aluminium powder is heated with MnO23 MnO2 (s) + 4 Al (s) → 3 Mn (l) + 2 Al2O3 (l) + Heat
(a) Is aluminium getting reduced?
(b) Is MnO2 getting oxidised?

AcademicChemistryNCERTClass 10

In the reaction,

3 MnO2 (s) + 4 Al (s) → 3 Mn (l) + 2 Al2O3 (l) + Heat

(a) Aluminium gets oxidized as oxygen gets combined with it to form Al2O3.

(b) MnO2 is reduced as oxygen is removed to produce Mn.
