Both samples shown above are green gases at room temperature. Will the properties of the two samples likely be the same or different?

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

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

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

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

Will the properties of the two samples likely be the same or different?

• 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.

Can one substance change into another substance? (read carefully)

• No, because things can mix, but they can't change into new things

• Yes, because new atoms can be created

• No, because atoms can not be destroyed

• Yes, because atoms can be rearranged.

Andres is a chemist working at a company that makes ink. To make a new kind of ink, Andres 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, Andres found two solid 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?

Samira 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. Samira 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. She created a model of the repeating groups of atoms that might make up the two ending substances.

• Samira's model correctly demonstrates how the properties changed with the rearrangement of the atoms. However not all atoms are accounted for. There is a missing reactant.

• Samira's model is correct because the properties are different and the atoms are rearranged.

• Samira's model is incorrect because not all atoms are accounted for

• Samira's model correctly demonstrates how the properties changed with the rearrangement of the atoms. However not all atoms are accounted for. There is a missing product.

A chemist mixed two samples together: a brown solid that melts at about 1,300°C and a colorless liquid that melts at about 20°C. She analyzed the results and found two ending substances. One of the ending substances melts at about 250°C. 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?
