Examples of homogeneous in the following topics:

  • Homogeneous versus Heterogeneous Solution Equilibria

    • The equilibrium constants for homogeneous and heterogeneous solutions need to be calculated differently.
    • The former are called homogenous reactions, and the later are called heterogeneous reactions.
    • A homogeneous equilibrium is one in which all of the reactants and products are present in a single solution (by definition, a homogeneous mixture).
    • Reactions between solutes in liquid solutions belong to one type of homogeneous equilibria.
  • Homogeneous Catalysis

    • Homogeneous catalysis is a class of catalysis in which the catalyst occupies the same phase as the reactants.
    • Catalysts can be classified into two types: homogeneous and heterogeneous.
    • Acid catalysis, organometallic catalysis, and enzymatic catalysis are examples of homogeneous catalysis.
    • Most often, homogeneous catalysis involves the introduction of an aqueous phase catalyst into an aqueous solution of reactants.
    • However, unlike with heterogeneous catalysis, the homogeneous catalyst is often irrecoverable after the reaction has run to completion.
  • The Chi-Square Distribution: Comparison Summary of the Chi-Square Tests Goodness-of-Fit, Independence and Homogeneity

    • Homogeneity: Use the Test for Homogeneity to decide if two populations with unknown distribution have the same distribution as each other.
  • Student Learning Outcomes

  • Heterogeneous Catalysis

    • Catalysts can be divided into two types, homogeneous or heterogeneous, depending on the reaction phase that they occupy.
    • Homogeneous catalysts are those that occupy the same phase as the reaction mixture (typically liquid or gas), while heterogeneous catalysts occupy a different phase.
  • Alloys

    • Partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on thermal history.
    • Partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on thermal history.
    • Alloys can be further classified as homogeneous (consisting of a single phase), heterogeneous (consisting of two or more phases), or intermetallic (where there is no distinct boundary between phases).
  • Summary of Formulas

    • Use the test for homogeneity to decide if two populations with unknown distributions have the same distribution as each other.
    • NOTE: The expected value for each cell needs to be at least 5 in order to use the Goodness-of-Fit, Independence and Homogeneity tests.
  • Substances and Mixtures

    • A homogeneous mixture is a mixture of two or more chemical substances (elements or compounds), where the different components cannot be visually distinguished.
    • Often separating the components of a homogeneous mixture is more challenging than separating the components of a heterogeneous mixture.
    • Distinguishing between homogeneous and heterogeneous mixtures is a matter of the scale of sampling.
    • In practical terms, if the property of interest is the same regardless of how much of the mixture is taken, the mixture is homogeneous.
    • Mixtures are described as heterogeneous or homogeneous.
  • Choosing the Main Points

    • A homogeneous audience is a group of people who share a consistent level of interest and expertise in your topic.
    • If you are addressing a homogeneous group, don't take their interest for granted.
    • It's not a free pass--a homogeneous audience is not a captive audience.
  • The Chi-Square Distribution: Test for Homogeneity

    • A different test, called the Test for Homogeneity, can be used to make a conclusion about whether two populations have the same distribution.
    • To calculate the test statistic for a test for homogeneity, follow the same procedure as with the Test of Independence.
    • We cannot use the Test for Homogeneity to make any conclusions about how they differ.
