  2. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    Stoichiometry measures these quantitative relationships, and is used to determine the amount of products and reactants that are produced or needed in a given reaction. Describing the quantitative relationships among substances as they participate in chemical reactions is known as reaction stoichiometry. In the example above, reaction ...

  3. Flow chemistry - Wikipedia

    en.wikipedia.org/wiki/Flow_chemistry

    Typically, non-compressible fluids are used with no gas volume so that the expansion factor as a function of pressure is small. Mixing can be achieved within seconds at the smaller scales used in flow chemistry. Heat transfer is intensified. Mostly, because the area to volume ratio is large.

  4. Ecological stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Ecological_stoichiometry

    Most work in ecological stoichiometry focuses on the interface between an organism and its resources. This interface, whether it is between plants and their nutrient resources or large herbivores and grasses, is often characterized by dramatic differences in the elemental composition of each part. The difference, or mismatch, between the ...

  5. Mass balance - Wikipedia

    en.wikipedia.org/wiki/Mass_balance

    where w C, w H, w S, w O refer to the mass fraction of each element in the fuel oil, sulfur burning to SO 2, and AFR mass refers to the air-fuel ratio in mass units. For 1 kg of fuel oil containing 86.1% C, 13.6% H, 0.2% O, and 0.1% S the stoichiometric mass of air is 14.56 kg, so AFR = 14.56. The combustion product mass is then 15.56 kg.

  6. Air–fuel ratio - Wikipedia

    en.wikipedia.org/wiki/Air–fuel_ratio

    Air–fuel equivalence ratio, λ (lambda), is the ratio of actual AFR to stoichiometry for a given mixture. λ = 1.0 is at stoichiometry, rich mixtures λ < 1.0, and lean mixtures λ > 1.0. There is a direct relationship between λ and AFR. To calculate AFR from a given λ, multiply the measured λ by the stoichiometric AFR for that fuel.

    The survey didn’t delve into why Gen Z workers are more challenging to work with than their peers, but it’s hard to ignore the fact that latest cohort of workers came of age during the pandemic.

  8. Redfield ratio - Wikipedia

    en.wikipedia.org/wiki/Redfield_ratio

    For his 1934 paper, Alfred Redfield analyzed nitrate and phosphate data for the Atlantic, Indian, Pacific oceans and Barents Sea. [1] As a Harvard physiologist, Redfield participated in several voyages on board the research vessel Atlantis, analyzing data for C, N, and P content in marine plankton, and referenced data collected by other researchers as early as 1898.

  9. Non-stoichiometric compound - Wikipedia

    en.wikipedia.org/wiki/Non-stoichiometric_compound

    Non-stoichiometric compounds are chemical compounds, almost always solid inorganic compounds, having elemental composition whose proportions cannot be represented by a ratio of small natural numbers (i.e. an empirical formula); most often, in such materials, some small percentage of atoms are missing or too many atoms are packed into an ...
