∆en-P-Cl3
∆en-H-N-O
∆en-C-H3-Oh

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.

it is stable as it is in group 0 which have full outer shells of electrons
