A scientist mixed two samples together: a
colorless liquid that melts at 12°C and a
yellow solid that melts at 390°С. She
analyzed the results and found two ending
substances. One of the ending substances
was a gray solid. This ending substance is
made up of the repeating group of atoms
shown above. Which of the diagrams to the
left shows the repeating groups of atoms
that make up the samples the scientist
mixed together?
