Chapter 2 Amplify Chemical Reactions

The diagram shows 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 there are more repeating groups of atoms in Sample 2.

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

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

• 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.

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.)

The diagram above shows the repeating groups of atoms that make up two samples. Both samples are gases at room temperature. Will the other properties of the samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)

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

• The other properties will likely be the same because both samples are gases at room temperature.

• The other properties will likely be different because there are more repeating groups of atoms in Sample 1.

• The other properties will likely be different because the repeating groups of atoms that make up the two samples have different numbers of atoms.

Asia mixed two samples together: a white solid that boils at 800°C and a colorless gas that boils at 70°C. She analyzed the results and found two ending substances. One of the ending substances boils at 245°C. This ending substance is made up of the repeating group of atoms shown above. Which of the diagrams(answers) shows the repeating groups of atoms that make up the samples the scientist mixed together?

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.)

The diagram above shows the repeating groups of atoms that make up two samples. Both samples are solids at room temperature. Will the other 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 other properties will likely be different because there are more repeating groups of atoms in Sample 2.

• The other properties will likely be different because the repeating groups of atoms that make up the two samples have different numbers of atoms.

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

• The other properties will likely be the same because both samples are solids at room temperature.

Jackson mixed two samples together: a colorless gas with no smell and a colorless liquid that smells like bleach. He analyzed the results and found two ending substances. One of the ending substances was a green gas. This ending substance is made up of the repeating group of atoms shown above. Which of the diagrams (answers) shows the repeating groups of atoms that make up the samples Jackson mixed together?

Alexa mixed two colorless substances together in a sealed container. The diagram above shows the repeating groups of atoms that make up the starting substances.

After mixing, she found two yellow substances in the sealed container. (Nothing escaped.) Which of the repeating groups of atoms below make up the ending substances? (Remember during a chemical reaction atoms rearrange to form a new substance.)

The diagram above shows the repeating groups of atoms that make up two samples. Both samples are red powdery solids at room temperature. Will the other properties of the two samples be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)

• The other properties will be different because there are more repeating groups of atoms in Sample 1.

• The other properties will be the same because both samples are red at room temperature.

• The other properties will be the same because both samples are powdery solids at room temperature.

• The other properties will be same because the repeating groups of atoms that make up the two samples are the same.
