  2. Equivalent (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Equivalent_(chemistry)

    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 ...

  3. European Qualifications Framework - Wikipedia

    en.wikipedia.org/wiki/European_Qualifications...

    The core of the EQF concerns eight reference levels describing what a learner knows, understands and is able to do – 'learning outcomes'. Levels of national qualifications will be placed at one of the central reference levels, ranging from basic (Level 1) to advanced (Level 8).

  4. Equivalent concentration - Wikipedia

    en.wikipedia.org/wiki/Equivalent_concentration

    Here, ⁠ 1 / f eq ⁠ can have a fractional (non-integer) value. In precipitation reactions, the equivalence factor measures the number of ions which will precipitate in a given reaction. Here, ⁠ 1 / f eq ⁠ is an integer value. Normal concentration of an ionic solution is also related to conductivity (electrolytic) through the use of ...

  5. Encephalization quotient - Wikipedia

    en.wikipedia.org/wiki/Encephalization_quotient

    Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species.

  6. Acid value - Wikipedia

    en.wikipedia.org/wiki/Acid_value

    V eq is the volume of titrant (ml) consumed by the crude oil sample and 1 ml of spiking solution at the equivalent point, b eq is the volume of titrant (ml) consumed by 1 ml of spiking solution at the equivalent point, 56.1 g/mol is the molecular weight of KOH, W oil is the mass of the sample in grams. The normality (N) of titrant is calculated as:

  7. Equivalence point - Wikipedia

    en.wikipedia.org/wiki/Equivalence_point

    The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of reactants have been mixed. For an acid-base reaction the equivalence point is where the moles of acid and the moles of base would neutralize each other according to the chemical reaction.

  8. National qualifications frameworks in the United Kingdom

    en.wikipedia.org/wiki/National_qualifications...

    Learning at this level is appropriate for people working in technical and professional jobs, and/or managing and developing others. Level 4 qualifications are at a level equivalent to Certificates of Higher Education. Level 3 Level 3 qualifications recognise the ability to gain, and where relevant apply a range of knowledge, skills and ...

  9. Sound level meter - Wikipedia

    en.wikipedia.org/wiki/Sound_level_meter

    Graph of LAeq sound level measurement calculated over 5 minutes Graph of a continuous LAeq sound level measurement. eq = equivalent. Equivalent values are averaged over longer time and thus easier to read on a display than sound level with F, S or I time weighting.
