  33. Matter
    Anything that takes up space and has mass.
  34. "Pure" Substance
    Form of matter that has a definite (constant) composition and distinct properties.
  35. Mixture
    Combination of two or more substances in which the substances retain their distinct identities.
  36. Compound
    A substance composed of atoms of two or more elements chemically united in fixed proportions.
  37. Solid
    Molecules are held close together in an orderly fashion with little freedom of motion.
  38. Liquid
    Molecules are held together but are not held rigidly in position.
  39. Gas
    Molecules are separated by distances that are large compared with the size of the molecules.
  40. Extensive property
    Depends on how much matter is being considered.

    Ex: Mass, Volume, Lenth
  41. Intensive property
    Does not depend on how much matter is being considered.

    Ex: Density, Temperature, Color
  42. Isotopes
    Atoms of the same element having a different number of neutrons.
  43. Law of definite proportions
    States that different samples of the same compound always contain its constituent elements in the same proportion by mass.
  44. Law of multiple proportions
    If two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other elements are in ratios of small whole numbers.
  45. Law of conservation of mass
    Matter can neither be created nor destroyed.
