GIVING BRAINLIEST!! PLEASE HELP The boiling points of the halogens F2, Cl2, Br2 and I2 increase in that order. This is best attributed to the differences in .

A)covalent bond strengths

B)dipole forces

C)london dispersion forces

D)hydrogen bonding

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.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

you need to have a picture of the atom that way we can answer it
