A. the amount of hydrogen bonding in the liquid B. the volume of the liquid C. the type of material the container is made of D. the viscosity of the liquid E. the relative magnitudes of cohesive forces in the liquid and adhesive forces between the liquid and its container

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.
