The diagram above shows the repeating groups of atoms that make up two samples. Both samples are red powdery solids 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 different because there are more repeating groups of atoms in Sample 1.
The other properties will be the same because both samples are red at room temperature.
The other properties will be the same because both samples are powdery solids at room temperature.
The other properties will be same because the repeating groups of atoms that make up the two samples are the same.
The diagram above shows the repeating groups of atoms that make up two samples. Both samples are solids at room temperature. Will the other 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 other properties will likely be different because there are more repeating groups of atoms in Sample 2.
The other properties will likely be different because the repeating groups of atoms that make up the two samples have different numbers of atoms.
The other 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 other properties will likely be the same because both samples are solids at room temperature.
The diagram above shows the repeating groups of atoms that make up two samples. Both samples are gases at room temperature. Will the other properties of the samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)
The other 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 other properties will likely be the same because both samples are gases at room temperature.
The other properties will likely be different because there are more repeating groups of atoms in Sample 1.
The other 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 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 other properties will likely be different because the repeating groups of atomThe properties will likely be the same because the repeating groups of atoms that make up the two samples have the same number of atoms.s that make up the two samples have different numbers of atoms.
How can we tell substances apart?
Different substances will have the same properties
The same substances will have different properties
Different substances will have different properties
I like potatoes!!!
Why do different substances have different properties?
Different substances will be made of different molecules
The same substances will have different molecules
Different substances will be made of the same molecules
