LEARNING OBJECTIVES

  • Distinguish between pure substance and mixtures:
    • A pure substance has a definite set of characteristic properties (density, mp, bp), whereas a mixture exhibits properties that are a mixture of the properties of the substance they contain.
    • A pure substance is composed of one kind of particle, whereas mixtures contain more than one kind of particle.
  • Describe how one could use differences in characteristic properties to separate the components of a mixture.
  • Sketch particle diagrams that distinguish compounds, elements and mixtures.
  • Distinguish elements from compounds in terms of differences in their properties.
  • Cite the evidence that supports the belief that some pure substances are “compounded” of simpler particles in a definite ratio.
  • Cite evidence for Avogadro’s Hypothesis.  Use this with evidence from combining volumes to deduce the formulas of some compounds.
  • State features of Dalton’s model of the atom; use composition by mass data to account for the laws of definite and multiple proportions.
