The model on the right looks bumpy but when you break a large so Crystal into the edges of the split often look straight and feels smooth is there a problem with the model use what you have learned about atoms to explain

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.
