Chemical Reactions

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.

The diagram above shows the repeating groups of atoms that make up two samples. Both samples are liquid at room temperature. Will the properties of the two samples likely be the same or different?

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

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

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