2,4,6-Trinitrobenzoic acid is prepared by oxidation of 2,4,6-trinitrotoluene (TNT). It is formed by oxidation of TNT and nitric acid with chlorate [2] and with dichromate. [3] Upon heating, 2,4,6-trinitrobenzoic acid undergoes decarboxylation to give 1,3,5-trinitrobenzene. [4]
Trinitrotoluene spin view. Trinitrotoluene (/ ˌ t r aɪ ˌ n aɪ t r oʊ ˈ t ɒ lj u iː n /), [5] [6] more commonly known as TNT (and more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene), [1] is a chemical compound with the formula C 6 H 2 (NO 2) 3 CH 3.
The National Numeracy Network (NNN) is a multidisciplinary US-based organization that promotes numeracy, i.e., the ability to reason and to apply simple numerical concepts. [1] The organization sponsors an annual conference and its website provides a repository of resources for teaching numeracy.
The National Assessment Program – Literacy and Numeracy (NAPLAN) is a series of tests focused on basic skills that are administered to Australian students in Years 3, 5, 7 and 9. These standardised tests assess students' reading, writing, language (spelling, grammar and punctuation) and numeracy and are administered by the Australian ...
2014: National Numeracy-commissioned research by Pro Bono Economics found that over the course of a year, the cost of low levels of numeracy is estimated to be around £20.2 billion which is roughly 1.3 per cent of GDP to the total UK economy. This cost is distributed between individuals (£8.8 billion), employers (£3.2 billion) and government ...
Trinitrobenzene is more explosive than TNT, but more expensive. [2] It is primarily used as a high explosive compound for commercial mining and military applications. It has also been used as a narrow-range pH indicator, an agent to vulcanize natural rubber, and a mediating agent to mediate the synthesis of other explosive compounds. [5]
In the U.S., it was found that Singapore math emphasizes the essential math skills recommended in the 2006 Focal Points publication by the National Council of Teachers of Mathematics (NCTM), the 2008 final report by the National Mathematics Advisory Panel, and the proposed Common Core State Standards, though it generally progresses to topics at ...
(2.4–4.8) × 10 28 (2.8–5.6) × 10 40 Wh A type Ia supernova explosion gives off 1– 2 × 10 44 joules of energy, which is about 2.4–4.8 hundred billion yottatons (24–48 octillion (2.4– 4.8 × 10 28) megatons) of TNT, equivalent to the explosive force of a quantity of TNT over a trillion (10 12) times the mass of the planet Earth
