PLEASEEE HELP A chemist mixed two substances
together: a blue powder with no smell
and a colorless liquid with a strong

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
