The diagram below shows the 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 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 below shows the 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 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 1.
• 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.

The diagram below 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? (Examples of properties are smell, color, and the temperature at which a substance melts.)

• 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.

The diagram below 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.

What is the reddish-brown substance in the water?

•  The reddish-brown substance is the same as the substance that makes up the pipes.

• The reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes.

• The reddish-brown substance is the same substance as the fertilizer.

Why is the reddish-brown substance not the same as either the fertilizer or the substance that makes up the pipes? Select the answer that would provide evidence for the strongest argument.

• The groups of atoms that make up the reddish-brown substance are not the same as the groups of atoms that make up the fertilizer and pipe. For example ...

• The properties of the three substances are different in color and texture, and the groups of atoms are not the same for each substance. For example ...

• The properties of the three substances are different in color and texture. For example ...

• The color of the fertilizer and pipe substance is different than the color of the reddish-brown substance. For example ...
