Examples
Gas stoichiometry calculations solve for the unknown volume or mass of a gaseous product or reactant.
For example, halite (NaCl), galena (PbS), and periclase (MgO) all belong to the hexaoctahedral point group (isometric family), as they have a similar stoichiometry between their different constituent elements.
Describing the quantitative relationships among substances as they participate in chemical reactions is known as reaction stoichiometry.
Diesel engines, in contrast, run lean, with more air available than simple stoichiometry would require.
Different hydrocarbon fuels have different contents of carbon, hydrogen and other elements, thus their stoichiometry varies.
For example, the stoichiometry of hydrogen and oxygen in H 2 O is 2:1.
