Compare and contrast aufbau principle and the pauli exclusion principle.

Explanation:

First, the Pauli exclusion principle lets us know that no two electrons can have the exact same quantum numbers. This means that two electrons in a single orbital must have opposite spins. ... Finally, the Aufbau Principle states that electrons fill lower energy orbitals before moving to higher energy orbitals

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
