Here are some of the best chemistry jokes to jot down before your next science class. If you're a student, use them to get on your teacher's good side, and if you're a teacher, use these to get ...
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 ...
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.
The book was also believed to be a source of inspiration to David Hahn, nicknamed "the Radioactive Boy Scout" by the media, who attempted to construct a nuclear reactor in his mother's shed, [2] although the book does not include any nuclear reactions. Due to safety concerns, the book was eventually pulled from library shelves. [3]
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
If you've come here seeking egg puns, good news — we've got eggs-actly what you're looking for. In fact, when it comes to eggs-cellent puns, this collection is nothing short of eggs-trordinary.
Images composed of simple shapes, lines, and letters such as those below should be recreated using vector graphics as an SVG file. These have a number of advantages, such as making it easier for subsequent editors to edit them, enabling arbitrary scaling at high quality, and sharp high-resolution renderings for print versions.
The only pictures floating around the place are of promethium chloride and promethium oxide, but not the metal itself. This is likely because the metal is not used for anything, it's hard to make, and there's no need to make any. I recently discovered a paper by a scientist who first made promethium metal, but it contained no images. So I'm out ...
