However, the chemical composition of many substances is already known and is expressed by their chemical formula. Chemical formulas indicate what kinds of elements and how many atoms of each are present in a substance. What are the types of chemical composition? There are percent compositions and...
On the test set, the F-scores were 77.8% (recall 71.2%, precision 85.8%) for the CEM task and 77.6% (recall 71.7%, precision 84.6%) for the CDI task. Missed terms were mainly due to tokenization issues, poor recognition of formulas, and term conjunctions. Conclusions We developed an ...
Chemistry is involved with various and diverse interactions of matter either around us or simply inside the laboratory. These are described using the language of chemistry, which consists of symbols, formulas and equations.
A chemical equation is composed of chemical formulas. It has reactants on the left and products on the right side of an arrow symbol (→). The arrow is usually read out as ‘yields’. In an equation, all chemical formulae on one side are separated by a plus sign. The physical state...
