Dimensional analysis may be used as a sanity check of physical equations: the two sides of any equation must be commensurable or have the same dimensions. A person who has calculated the power output of a car to be 700 kJ may have omitted a factor, since the unit joules is a measure of energy, not power (energy per unit time).
Sanity (from Latin: sānitās) refers to the soundness, rationality, and health of the human mind, as opposed to insanity.A person is sane if they are rational.In modern society, the term has become exclusively synonymous with compos mentis (Latin: compos, having mastery of, and Latin: mentis, mind), in contrast with non compos mentis, or insanity, meaning troubled conscience.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Sanity is the state of being of sound mind and therefore legally responsible for one's actions. Sanity may also refer to: "Sanity" (song), a song by Killing Joke "Sanity", a song by Matt Brouwer from Imagerical; Sanity (music store), an Australian entertainment retailer; Sanity (professional wrestling), a professional wrestling faction in WWE
Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air.The measurement of turbidity is a key test of both water clarity and water quality.
In chemistry, chemical purity is the measurement of the amount of impurities found in a sample. Several grades of purity are used by the scientific, pharmaceutical, and industrial communities. [1] [2] Some of the commonly used grades of purity include:
In chemistry and materials science, impurities are chemical substances inside a confined amount of liquid, gas, or solid. They differ from the chemical composition of the material or compound. [ 1 ] Firstly, a pure chemical should appear in at least one chemical phase and can also be characterized by its phase diagram .
