Classify the substance shown in the sketch below. You can click the other tabs in the sketch to get a magnified view. Be sure you check all the boxes on the right-hand side that are correct for this substance. Note for advanced students: in some sketches the distance between particles has been exaggerated to make it easier to see each individual particle. normal substance 1000X 10,000,000X classification (check all that apply) gas liquid solid element compound mixture solution pure substance homogeneous mixture heterogeneous mixture x

In chemistry, compounds are classified as solid, liquid, or gas based on their physical and chemical properties. The intermolecular distance is one such factor that helps in classification.A mixture consists of two or more components in a liquid or gaseous phase. The image at 10,000,000x zoom shows that only molecules made of two atoms are present. Hence, this is not a mixture. It is also not a solution as two components (solvent and solute) are required in order to form a solution. A compound is formed by the bonding between two or more atoms of different elements. Hence, this is not a compound as the atoms are of the same element. Element is a chemical species that is entirely made up of one sort of atom. It is evident that there are only one-colored spheres (green) bonded to one another forming a molecule. Hence, it is completely made up of only one type of element. The intermolecular distance between molecules is large which indicates that it is a gas. Therefore, the correct options are gas, element and pure substance.
