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.)

Question

Responses

a
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 the same because the repeating groups of atoms that make up the two samples are the same.

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

c
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 green at room temperature.

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

Answer 1

The best response among the options provided is:

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

This response indicates that the fundamental molecular structure is identical, which typically leads to similar physical and chemical properties despite the state of matter or appearance. If the repeating units of atoms are the same, their inherent properties such as smell, color, and melting point will also be similar. The other options focus on superficial similarities (color and state) or provide an incorrect assumption about the relationship between the number of repeating groups and properties.
