Front

Will the properties of the two samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)

Back

The properties will likely be different because the repeating groups of atoms that make up each sample are different.

Tiana is a chemist who is making a chemical to add to swimming pools in order to make the water safer. She mixed two 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, Tiana 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?
