  2. Hammond's postulate - Wikipedia

    en.wikipedia.org/wiki/Hammond's_postulate

    Another significance of Hammond’s postulate is that it permits us to discuss the structure of the transition state in terms of the reactants, intermediates, or products. In the case where the transition state closely resembles the reactants, the transition state is called “early” while a “late” transition state is the one that closely ...

  5. Effusion - Wikipedia

    en.wikipedia.org/wiki/Effusion

    In physics and chemistry, effusion is the process in which a gas escapes from a container through a hole of diameter considerably smaller than the mean free path of the molecules. [1] Such a hole is often described as a pinhole and the escape of the gas is due to the pressure difference between the container and the exterior.

  6. Chemistry education - Wikipedia

    en.wikipedia.org/wiki/Chemistry_education

    Chemistry education (or chemical education) is the study of teaching and learning chemistry. It is one subset of STEM education or discipline-based education research (DBER). [1] Topics in chemistry education include understanding how students learn chemistry and determining the most efficient methods to teach chemistry.

  7. Combustion analysis - Wikipedia

    en.wikipedia.org/wiki/Combustion_analysis

    Combustion analysis is a method used in both organic chemistry and analytical chemistry to determine the elemental composition (more precisely empirical formula) of a pure organic compound by combusting the sample under conditions where the resulting combustion products can be quantitatively analyzed.

  8. The Golden Book of Chemistry Experiments - Wikipedia

    en.wikipedia.org/wiki/The_Golden_Book_of...

    The book was also believed to be a source of inspiration to David Hahn, nicknamed "the Radioactive Boy Scout" by the media, who attempted to construct a nuclear reactor in his mother's shed, [2] although the book does not include any nuclear reactions. Due to safety concerns, the book was eventually pulled from library shelves. [3]
