It is assumed that for strong acids, the dissociation reaction goes to completion (i.e., no unreacted acid remains in solution).
For weak acids the dissociation reaction does not go to completion, an equlibrium is set up between the ions and the acid.
Water is a very weak acid and in general it supplies far fewer than the acid dissolved in it.

The modern study of genetics at the level of DNA is known as molecular genetics and the synthesis of molecular genetics with traditional Darwinian evolution is known as the modern evolutionary synthesis.
All nucleic acid synthesis in a cell occurs in the 5'-3' direction, because new monomers are added via a dehydration reaction that uses the exposed 3' hydroxyl as a nucleophile.
Sets of three nucleotides, known as codons, each correspond to a specific amino acid or to a signal; three codons are known as "stop codons" and, instead of specifying a new amino acid, alert the translation machinery that the end of the gene has been reached.

 Enhancing a biomedical information extraction system with dictionary mining and context disambiguation
To disambiguate the admissible possibilities, the standard approach is to rely on the context in which the entity appears to provide additional clues to the intended meaning [16].
In [14] the one-sense-per-discourse [20] hypothesis was applied to disambiguation, exploiting the fact that the sense of a term is highly consistent within a given document.
The performance of the disambiguator based on learning only is rather poor on this set compared with its performance on the earlier locally disambiguated set.

 Resin Summary
Resin acids can be dissolved in alkalis to form resin soaps, from which the purified resin acids are regenerated by treatment with acids.
Abietic acid can also be extracted from rosin by means of hot alcohol; it crystallizes in leaflets, and on oxidation yields trimellitic acid, isophthalic acid and terebic acid.
Pimaric acid closely resembles abietic acid into which it passes when distilled in a vacuum; it has been supposed to consist of three isomers.

Zwitterions contain an anionic center and a cationic center in the same molecule but are not considered to be salts.
When salts are dissolved in water, they are called electrolytes, and are able to conduct electricity, a property that is shared with molten salts.
Salts of strong acids and strong bases ("strong salts") are non-volatile and odorless, while salts of either weak acids or weak bases ("weak salts") may smell after the conjugate acid (e.g.
