Gas stoichiometry is the quantitative relationship (ratio) between reactants and products in a chemical reaction with reactions that produce gases. Gas stoichiometry applies when the gases produced are assumed to be ideal, and the temperature, pressure, and volume of the gases are all known. The ideal gas law is used for these calculations.
Jeremias Benjamin Richter (German: [ˈʁɪçtɐ]; 10 March 1762 – 4 May 1807) [1] was a German chemist.He was born at Hirschberg in Silesia, became a mining official at Breslau in 1794, and by 1800 was appointed assessor to the department of mines and chemist to the royal porcelain factory at Berlin, where he died.

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.
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.
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.
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.

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.
