Properties

Name	Type	Description
`id`readonly	`string`	Unique, and it is what a substance and a reaction name. Phase is part of it: `H2O(l)`.
`formula`readonly	`Readonly<Record<string, number>>`	Moles of each element per mole of species, keyed by symbol. More Fractional subscripts are allowed and are not a compromise: an average protein residue is `C4.4H7.7N1.2O1.4S0.04`, and rounding those to integers breaks element balance by percent-scale amounts across a whole body.
`phase`readonly	`Phase`
`formationEnthalpy`readonly	`number`	Standard enthalpy of formation at 298.15 K, J/mol. More Every reaction's `ΔH` is derived from these by Hess's law rather than typed in, so a wrong value here is wrong in every reaction that touches the species at once — which is a bug that can be found, unlike a single reaction quietly disagreeing with its own species.
`cpA`readonly	`number`	Specific heat at 298.15 K, J/(kg·K).
`cpB`readonlyoptional	`number`	Linear coefficient, J/(kg·K²). Absent means a constant heat capacity.
`pseudo`readonlyoptional	`boolean`	A lumped repeat unit or an average composition rather than a real molecule.
