This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
Methylisothiazolinone (/ ˌ m ɛ θ əl ˌ aɪ s oʊ ˌ θ aɪ. ə ˈ z oʊ l ɪ n oʊ n /), MIT, or MI, is the organic compound with the formula S(CH) 2 C(O)NCH 3. It is a white solid. Isothiazolinones, a class of heterocycles, are used as biocides in numerous personal care products and other industrial applications.
Pronounced "A-star". A graph traversal and pathfinding algorithm which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. abductive logic programming (ALP) A high-level knowledge-representation framework that can be used to solve problems declaratively based on abductive reasoning. It extends normal logic programming by allowing some ...
The artificial intelligence (AI) boom has brought with it a cornucopia of jargon — from "generative AI" to "synthetic data" — that can be hard to parse. An AI glossary: The words and terms to ...
In probability theory and information theory, the mutual information (MI) of two random variables is a measure of the mutual dependence between the two variables. More specifically, it quantifies the " amount of information " (in units such as shannons ( bits ), nats or hartleys ) obtained about one random variable by observing the other random ...
In the Simmons–Smith reaction, it is a source of methylene. [4] In fact the Simmons–Smith reaction does not produce free carbene but proceeds via Zn-CH 2 I intermediates. Diiodomethane is also a source of the equivalent of CH 2+ 2. The synthesis of Fe 2 (CH 2)(CO) 8 illustrates this reactivity: [5] Na 2 Fe 2 (CO) 8 + CH 2 I 2 → Fe 2 (CH 2 ...
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 multiple choice question, with days of the week as potential answers. Multiple choice (MC), [1] objective response or MCQ (for multiple choice question) is a form of an objective assessment in which respondents are asked to select only the correct answer from the choices offered as a list.
