The purpose, rather than to standardize state abbreviations per se, was to make room in a line of no more than 23 characters for the city, the state, and the ZIP code. [4] Since 1963, only one state abbreviation has changed.
Mn(IV) is somewhat enigmatic because it is common in nature but far rarer in synthetic chemistry. The most common Mn ore, pyrolusite, is MnO 2. It is the dark brown pigment of many cave drawings [31] but is also a common ingredient in dry cell batteries. [32] Complexes of Mn(IV) are well known, but they require elaborate ligands.

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.
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 ...
Wolframite is an iron, manganese, and tungstate mineral with a chemical formula of (Fe,Mn)WO 4 that is the intermediate mineral between ferberite (Fe 2+ rich) and hübnerite (Mn 2+ rich). [4] Along with scheelite , the wolframite series are the most important tungsten ore minerals.
