A chemist mixed two substances together: a blue powder with no smell
and a colorless liquid with a strong
smell. Their repeating groups of atoms
are shown above on the left. After they
were mixed, the chemist analyzed the
results and found two substances. One
ending substance had the repeating
group of atoms shown above on the
right.
Is the ending substance the same
substance as the blue powder? What
happened to the atoms of the starting
substances when the ending
substances formed? Be sure to explain
your answers to both of these

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 electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

the dissolution of polymer can be thermodynamically described in 2 steps.
