Jamie works at a company that makes cleaning chemicals. She is trying to make a chemical that smells like flowers. She took two samples that were gases at room temperature and mixed them in a sealed container. The diagram above shows the repeating groups of atoms that make up the two starting substances.

After mixing, Jamie found two substances that smelled like flowers 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?

Patrik works at a company that makes paper and needs a chemical to make the paper brighter. He mixed two colorless substances together in a sealed container. The diagram above shows the repeating groups of atoms that make up the two starting substances.

After mixing, Patrik found two white 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?

Damian mixed two samples together: a red liquid that smells irritating and a black solid with no smell. He analyzed the results and found two ending substances. One of the ending substances was a yellow 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 Damian mixed together?

A chemist mixed two substances together: a blue powder with no smell and a colorless liquid with a strong smell. Their repeating groups of atoms are shown above on the left. After they were mixed, the chemist analyzed the results and found two substances. One 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 questions.

Sahil watched a demonstration in which a scientist combined two substances in a sealed container and analyzed the results. The ending substances did not look the same as the starting substances. Sahil was given a diagram with the repeating groups of atoms that make up the starting substances, plus information about the properties of the starting and ending substances. He created a model of the repeating groups of atoms that might make up the two ending substances. Does his model correctly show why the properties of the ending substances are different from the properties of the starting substances? Describe what could be correct or incorrect about his model.
