An equivalent (symbol: officially equiv; [1] unofficially but often Eq [2]) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. It is an archaic quantity that was used in chemistry and the biological sciences (see Equivalent weight § In ...
In chemistry, the equivalent concentration or normality (N) of a solution is defined as the molar concentration c i divided by an equivalence factor or n-factor f eq:
In chemistry, equivalent weight (also known as gram equivalent [1] or equivalent mass) ...
In the analysis of the molecular formula of organic molecules, the degree of unsaturation (DU) (also known as the index of hydrogen deficiency (IHD), double bond equivalents (DBE), or unsaturation index [1]) is a calculation that determines the total number of rings and π bonds. A formula is used in organic chemistry to
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.
“Many Japanese foods, such as natto and miso, are fermented, and this technology could expand into these areas,” Uetsuki said. The company’s developing space brewing equipment, with a ...
Faraday discovered that when the same amount of electric current is passed through different electrolytes connected in series, the masses of the substances deposited or liberated at the electrodes are directly proportional to their respective chemical equivalent/equivalent weight (E). [3]
It’s important to incorporate a variety of hand positions during your strength training so that you strengthen your hands and arms in as many ways as possible, says Seki.
