Question

Write the balance chemical equation for the chemical reaction between Manganese dioxide and
Aluminum powder. What happens if Manganese powder is heated with Aluminum oxide?​

Answer 1

★When manganese dioxide (MnO2) is heated with aluminium powder, displacement reaction takes place, and manganese is obtained as the product along with aluminium oxide. It is an exothermic reaction and hence Mn is obtained in molten form.

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

★Iron (III) oxide is heated with aluminium powder to form iron and aluminium oxide. This is another example of a displacement reaction and is highly exothermic. This reaction is also known as thermit reaction.
