A chemist mixed two samples together: a gray liquid that boils at 103°C and a colorless gas that boils at 19°C. She analyzed the results and found two ending substances. One of the ending substances was a pink liquid. 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 chemist mixed together?

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?

The diagram above shows the repeating groups of atoms that make up two samples. 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.)

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

• The properties will likely be different because there are more repeating groups of atoms in Sample 2.

• The properties will likely be the same because the repeating groups of atoms that make up the two samples have the same number of atoms.

• The properties will likely be the same because the repeating groups of atoms that make up the two samples have two of the same types of atoms.

Serena mixed two samples together: a gray solid that smells like flowers and a gray solid that smells like bleach. She analyzed the results and found two ending substances. One of the ending substances was a white 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 Serena mixed together?

Two samples a colorless liquid that melts at 12°C and a yellow solid that melts at 390°C are mixed together. One of the ending substances was a gray solid. The ending substance, made up of repeating group of atoms, are shown above. Which of the diagrams (answers) shows the repeating groups of atoms that make up the samples he mixed together? (Remember, when new substances form the reactants rearrange to form different products with the same atoms.)

A company needs to create frying pans with a high melting point. To create this new substance, workers mixed together two substances in a sealed container. The diagram above shows the repeating groups of atoms that make up the two starting 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? (Remember, atoms on the reactant side of the equation, must be on the product side in the same amount but rearranged to form a new substance.)

Tyler is working at a company that makes ink. To make a new kind of ink, Tyler mixed two liquid substances together in a sealed container. The diagram above shows the repeating groups of atoms that make up the two starting substances.

After mixing, he found two solid substances in the sealed container. (Nothing had escaped.) Which of the diagrams (answers) shows the repeating groups of atoms that make up the ending substances? (Remember when a chemical reaction occurs the atoms rearrange to form a new substance.)
