An element with an electronegativity of 0.9 bonds with an element with an electronegativity of 3.1. Which phase best describes the bond between these elements.

A. lonic and formed between two nonmentals

B. lonic and formed between a metal and a nonmetal

C. Covalent and formed between two nonmetals

D. Covalent and formed between a metal and a nonmetal

B

Explanation:

I look it up and it is B B B B B

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.
