The force of gravity between a planet and its moon is 371 N. If the planet has a mass of 4 × 10^22 kg and the moon has a mass of 5 × 10^5 kg, what is the distance between their centers?

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.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

c. orbital shape i hope this is correct
