Question

aluminium metal displaces manganese from manganese (IV) oxide giving manganese and aluminium oxide.which is more reactive:mangenese or aluminium​

Answer 1

Explanation:

Aluminium Aluminium is more reactive

Answer 2

Answer:

Al leads Mn in the ease of oxidation or Al is more strongly reducing than Mn hence Al is more reactive than manganese. See activity series table given below. This is also reflected in the first ionization energy values (see figure below), Al has a lower first ionization energy than Mn. Lower the ionization energy, more reactive the element is.
