Consider the following substance descriptions. Does the evidence support that they are the same substances?

Substance 1: white, small, grainy, crystals

Substance 2: black, fine powder.

• YES

• NO

The diagram above shows the repeating groups of atoms that make up two samples. Both samples are green gases 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 the same because the repeating groups of atoms that make up the two samples are the same.

• 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 both samples are green at room temperature.

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