  • How do chemists determine if a gemstone is a real diamond?
    By testing if it can dissolve in water.
    By looking for the presence of carbon atoms.
    By examining its price.
    By checking if it contains zirconium.
  • What does John Dalton’s atomic theory propose?
    Matter is made of tiny pieces called atoms.
    Matter is made of light.
    Matter is made of energy.
    Matter is made of molecules.

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

  • What makes Isovaleric acid smell unpleasant?
    It is a solid at room temperature.
    It is colorless.
    It is made of sulfur atoms.
    It has a slightly different atomic structure than ethyl buty
  • What is cubic zirconia made of?
    Molecules of gold
    Carbon and hydrogen atoms

  • What makes substances have different properties?
    The number and type of atoms that repeat in their structure.
    Their atomic weight.
    Their shape and size.
    The temperature at which they are found.
