In a chemical reaction, the atoms or starting molecules, are different from the products or ending molecules. atoms are neither created, nor destroyed – simply rearranged asare and new are which occurs due to the transfer of .

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.
