6. Santiago is a chemist working to make a new kind of antacid, which is a medicine
that helps with stomach pain. He mixed two
powdery solid substances together in a
sealed container. The diagram above shows
the repeating groups of atoms that make up
the two starting substances.
After mixing, Santiago found two liquid
substances in the sealed container.
(Nothing had escaped.) Which of the
diagrams to the left shows the repeating
groups of atoms that make up the ending
substances?
