3. A company that makes frying pans needs to create a new substance to coat the pans.
The substance must have a high melting
point. To create this new substance, workers
mixed together two substances that melt at
low temperatures in a sealed container. The
diagram above shows the repeating groups
of atoms that make up the two starting
substances.
After mixing, the workers found two
substances that melt at higher
temperatures 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?
