Amplify Science Chemical Reactions

Stephanie combined two substances in a sealed container and analyzed the results. The ending substances did not look the same as the starting substances. She 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. Stephanie created a model of the repeating groups of atoms that might make up the two ending substances.

• Stephanie'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.

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

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

• Stephanie'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.

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.
