Avogadro constant (N A) The ratio of the number of discrete constituent particles (such as molecules, atoms, or ions) to the amount of a substance, defined as exactly 6.022 140 76 × 10 23 mol −1. Avogadro number The number of discrete constituent particles in one mole of a substance, defined as exactly 6.02214076 × 10 23.
English written syllabification therefore deals with a concept of "syllable" that does not correspond to the linguistic concept of a phonological (as opposed to morphological) unit. As a result, even most native English speakers are unable to syllabify words according to established rules without consulting a dictionary or using a word processor.
Unicode (hex) U+0329. A syllabic consonant or vocalic consonant is a consonant that forms a syllable on its own, like the m, n and l in some pronunciations of the English words rhythm, button and bottle, respectively. To represent it, the understroke diacritic in the International Phonetic Alphabet is used, U+ 0329 ̩ COMBINING VERTICAL LINE ...
A syllable is a unit of organization for a sequence of speech sounds, typically made up of a syllable nucleus (most often a vowel) with optional initial and final margins (typically, consonants). Syllables are often considered the phonological "building blocks" of words. [1] They can influence the rhythm of a language, its prosody, its poetic ...
A carbon–carbon bond is a covalent bond between two carbon atoms. [1] The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms. The carbon–carbon single bond is a sigma bond and is formed between one hybridized orbital from each of the carbon atoms. In ethane, the orbitals are sp 3 ...
Syllabic verse. Syllabic verse is a poetic form having a fixed or constrained number of syllables per line, while stress, quantity, or tone play a distinctly secondary role—or no role at all—in the verse structure. It is common in languages that are syllable-timed, such as French or Finnish, as opposed to stress-timed languages such as ...
Y-cluster reductions. Y-cluster reductions are reductions of clusters ending with the palatal approximant /j/, which is the sound of y in yes, and is sometimes referred to as "yod", from the Hebrew letter yod (h), which has the sound [j]. Many such clusters arose in dialects in which the falling diphthong /ɪu/ (the product of the merger of ...
For example, sulfuric acid (H 2 SO 4) is a diprotic acid. Since only 0.5 mol of H 2 SO 4 are needed to neutralize 1 mol of OH −, the equivalence factor is: feq (H 2 SO 4) = 0.5. If the concentration of a sulfuric acid solution is c (H 2 SO 4) = 1 mol/L, then its normality is 2 N. It can also be called a "2 normal" solution.
