Finally, expert chemists in our study used classification schemes that are not necessarily traditionally taught in classroom chemistry (e.g. the structure of substances is more relevant to them than their composition when classifying substances as compounds or elements). This result suggests that ...
the acceleration of chemical reactions by substances not consumed in the reactions themselves—substances known ascatalysts. The study of catalysis is of interest theoretically because of what it reveals about the fundamental nature of chemical reactions; in practice, the study of catalysis is important...
A poison in aliquidform can be absorbed by ingestion or by inhalation or through the skin. Poisons that are gases at room temperature (e.g., carbon monoxide) are absorbed mainly by inhalation, as are vapours, which are the gas phase of substances that are liquids at room temperature andat...

In fact, almost the only methods of classification available to historical chemists, before compound structures were well understood, were (i) based on the observation of reactivity through means of performing controlled reactions between different substances; or (ii) based on the origin of the ...
The state of the field of methods for the calculation of molar refractions fs discussed. Tables of covalent refractions are represented, which were calculated from measurements of simple substances, elemento-organic compounds, and by the... SS Batsanov - 《Journal of Structural Chemistry》 被引量...
The escalating demand for palm oil necessitates enhanced production strategies. As the trend shifts towards automated harvesting to meet the demand, precis
Dietary carbohydrates are a group of chemically defined substances with a range of physical and physiological properties and health benefits. As with other macronutrients, the primary classification of dietary carbohydrate is based on chemistry, that is character of individual monomers, degree of polymeriz...
