The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Nomenclature of Inorganic Chemistry, IUPAC Recommendations 2005 is the 2005 version of Nomenclature of Inorganic Chemistry (which is informally called the Red Book). It is a collection of rules for naming inorganic compounds, as recommended by the International Union of Pure and Applied Chemistry (IUPAC).
Bis(trimethylsilyl)acetamide (BSA) is an organosilicon compound with the formula MeC(OSiMe 3)NSiMe 3 (Me = CH 3). It is a colorless liquid that is soluble in diverse organic solvents, but reacts rapidly with moisture and solvents containing OH and NH groups .
Bisj pole, or Bis pole, is a ritual artifact of the Asmat people of New Guinea Bismarck Municipal Airport , North Dakota, U.S., IATA code and FAA LID: BIS See also
Magnesocene is a white solid at room temperature. [1] It has a melting point of 176 °C, though at atmospheric pressures it sublimes at 100 °C. [1] Unlike ferrocene, magnesocene displays slight dissociation and subsequent ion association in polar, electron-donating solvents (such as ether and THF).
5 C 6 H 5 MgBr + 4 CrCl 3 → (C 6 H 5) 5 CrBr + 2 MgBr 2 + 3 MgCl 2 + 3 CrCl 2. This event marked an advance in organochromium chemistry at the time and "(C 6 H 5) 5 CrBr" was described to have salt-like properties. However, the reported workup procedures for "(C 6 H 5) 5 CrBr" was challenging and the yield was low.
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 ...
