  • How do chemists determine if a gemstone is a real diamond?
    By looking for the presence of carbon atoms.
    By examining its price.
    By checking if it contains zirconium.
    By testing if it can dissolve in water.

  • What is the difference between molecules and extended structures?
    Molecules are always solid; extended structures are liquid.
    Molecules are separate units; extended structures are interc
