The need to limit antibiotic therapy due to the spreading resistance of pathogenic microorganisms to these medicinal substances stimulates research on new therapeutic agents, including the treatment and prevention of animal diseases. This is one of the g
The first skill is being able to draw proper Lewis structures for a molecule.To succeed in organic chemistry you absolutely need to be able to do this in your sleep.The Lewis structure should account for all the electrons around an atom, including the often-hidden lone pairs of electrons if...
More traditional, less standardized names still linger in chemistry, however. For example, many fluoride rinses list stannous fluoride as an ingredient. Stannous refers to tin(II), so the chemical formula for stannous fluoride is SnF2. Other commonly used nonstandard names include ferric [iron(III...

An atom that has an equal number of protons and electrons is neither positive nor negative -- it has no net charge. If that atom gains or loses electrons, however, it may become a cation, an ion with a positive charge, or an anion, an ion with a negative

Stereochemical nomenclature remains a point of attention; especially now different fields in chemistry become more and more entwined. The ubiquitously used terminology "amplification of chirality" is fundamentally incorrect, as chirality cannot be amplified. Instead, we now recommend "amplification of ...
see "Nomenclature of Organic Chemistry: IUPAC Recommendations and Preferred Names, 2013" by Favre and Powel (that is the IUPAC BLUE BOOK published by IUPAC with their rules in it. The horses mouth). Chapter P-9 has the relevant rules. But again, the question wasn't which is the preferred...
the indents I have used do not affect the how the code is processed, they just make it more readable. The beauty of these subfigures is that we can refer to each of them individually in the text due to their individual labels—but we can also give the whole figure a captio...
of TeX primitives. The set of 9 TeX engines analyzed to produce the primitive-command reference data do, of course, have many commands in common but each TeX engine also has its own primitive commands, added by its developers, to provide support for the features specific to that “version”...
