Here we have the most important aspects of the concept of the chemicalcompound. The concept of chemicalcompound is basic to modern chemistry and is reflected in theories of the composition and transformation of chemical substances. A method which played a significant role in the development of the concept of the chemicalcompound, was the extraction of copper through cementation. It was this revolutionized commercial practice that initiated a process of reflection from which the concept of the chemicalcompound emerged. The development of the idea of producing artifacts and the emergence of the first ideas of the chemicalcompound are closely related. Fruiting frequency was not significantly correlated with any chemicalcompound. This suggests that young leaves may contain higher concentration of some chemicalcompound which induces recruitment. The first ideas of the chemicalcompound discussed by the authors of chemical-pharmaceutical works during the seventeenth century referred to precisely such products, which were viewed as artifacts. The modern concept of the chemicalcompound was essentially the product of a consideration of the chemical operations of analysis and synthesis performed in the metallurgical and pharmaceutical trades. The idea of conservation inherent in the concept of the chemicalcompound shares with the seventeenth-century mechanical corpuscular theory that both assume the conservation of particles or corpuscles. This common feature of all variants of the idea of the chemicalcompound can well be illuminated by comparison with the mechanical corpuscular theory of the seventeenth century. In this case a chemicalcompound (in the contemporary sense), a silver or gold amalgam, is produced, which is then heated to separate the mercury from the silver or gold. Thus, whereas one chemicalcompound did show significant differences among parent trees, overall, chemical compounds and their compositions in dipterocarp seeds did not differ widely among individual trees within species. Emissions of heavy metals into the atmosphere are not speciated by individual chemicalcompound type. From the Hansard archive Example from the Hansard archive.
