The table shows the average distance between the molecules of a substance in the solid, liquid, and gaseous states. X | 10^-9 cm
Y | 10^-11 cm
Z | 10^-7 cm

Which of the following is the correct order of the relative strengths of the intermolecular forces in the three states?

A. Y > Z > X
B. Z > X > Y
C. X > Z > Y
D. Y > X > Z

c, liquids evaporate, creating a gas

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.

yes the answer is total mass in unchanged   : )
