Each peak represents a component present in the sample. Retention time is time interval between sample injection and the maximum of the peak. It is characteristic of the identity of the component under the operating conditions. Identity of the component can be confirmed by making injections of ref...
To this end, however, we first need a comprehensive conception of what constitutes achemistry-likereaction network. The different representations used in the literature highlight the fact that it is far from obvious which graphs or hypergraphs properly describechemicalRNs among a possibly much larger ...
Computational Chemistry Molecular Modelling Statistical Mechanics 1Introduction The general framework to describe and predict the behavior of macroscopic matter, statistical mechanics, was laid down in the 19th century by Boltzmann and Gibbs. The first ingredient of this theoretical framework is the atomisti...
Biotin, also called vitamin H (the H represents Haar und Haut, German words for "hair and skin") or vitamin B7, is a water-soluble B vitamin. It is involved in a wide range of metabolic processes, both in humans and in other organisms, primarily related to the utilization of fats, ca...
Given that the molecular mass of a compound is 360 g/mol, and that it has an empirical formula of CH2O, what is its' molecular formula? What is the empirical formula for carbon dioxide? The molecular formula of most monosaccharides represents a multiple of: a. CHO. b. CHO_{2}. c. ...
Energy is needed to convert plastic resin into plastic bottles. Plastic resin is melted and injected into a mold, and then heated and formed into bottles.This final process represents about eight percent of a plastic bottle's carbon footprint. ...
Protons have slightly less mass than the neutrons in the nucleus, but they are 1,836 times more massive than electrons. The actual mass of the proton is 1.6726 x 10^-27 kilograms, which is a very small mass indeed. The symbol "^-" represents a negative exponent. This number is a deci...
Beyond the practical importance for the generation of random chemistries, it is also of interest to ask whether and to what extent the stoichiometry of a RN constrains the underlying chemistry, i.e., the composition of com- pounds and the type of reactions. Chemical reaction networks have been...

Existing instructional materials for chemistry offer a huge range of different external representations that can be used by chemistry teachers to support students’ understanding of chemical concepts like the concept structure of matter . In science, dif
