We applied a mixed‐method research design to investigate the patterns of reasoning used by novice undergraduate chemistry students to classify chemical substances as elements, compounds, or mixtures based on their particulate representations. We were interested in the identification of the representational...

Biomedical relation classification has been significantly improved by the application of advanced machine learning techniques on the raw texts of scholarly publications. Despite this improvement, the reliance on large chunks of raw text makes these algorithms suffer in terms of generalization, precision, ...
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 family also includes such familiar substances as cholesterol and the carbohydrates. As we noted in Chapter 4 “Covalent Bonding and Simple Molecular Compounds”, Section 4.6 “Introduction to Organic Chemistry”, methanol (CH3OH) and ethanol (CH3CH2OH) are the first two members of the ...
