The kempyang and ketuk are two instruments in the gamelan ensemble of Indonesia, generally played by the same player, and sometimes played by the same player as the kenong. They are important beat-keepers in the colotomic structure of the gamelan. Depending on the structure, they play different, repeating patterns every gongan. Not all ...
Ladrang form on the phrase making or colotomic instruments. p = kempyang, t = ketuk, ⋅ = pause, N = kenong, P = kempul, GONG = gong ageng. [1] Colotomy is an Indonesian description of the rhythmic and metric patterns of gamelan music. It refers to the use of specific instruments to mark off nested time intervals, or the process of dividing ...
Negative ion reaction equations Negative air ions (NAI) are important air component, generally referring to the collections of negatively charged single gas molecules or ion clusters in the air. They play an essential role in maintaining the charge balance of the atmosphere.
A hydroxide ion acting as a nucleophile in an S N 2 reaction, converting a haloalkane into an alcohol. In chemistry, a nucleophile is a chemical species that forms bonds by donating an electron pair. All molecules and ions with a free pair of electrons or at least one pi bond can act as nucleophiles.
In chemistry, the common-ion effect refers to the decrease in solubility of an ionic precipitate by the addition to the solution of a soluble compound with an ion in common with the precipitate. [1] This behaviour is a consequence of Le Chatelier's principle for the equilibrium reaction of the ionic association / dissociation .
Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
Monofluorophosphate is an anion with the formula PO 3 F 2−, which is a phosphate group with one oxygen atom substituted with a fluoride atom.The charge of the ion is −2. The ion resembles sulfate in size, shape and charge, and can thus form compounds with the same structure as sulfate
The United Nations security Council's Committee of Good Offices on the Indonesian question was established, pursuant to a resolution of the Security Council of 25 August 1947, to assist in the pacific settlement of the dispute between the Netherlands and the Republic of Indonesia, at an informal meeting of the Committee convened by the Secretary-General of the United Nations at Lake Success ...
