A symbolic representation of a chemical transformation whose coefficients encode relative stoichiometric amounts and whose notation may state phase, charge, and conditions.

This is an authored directed relation from the source endpoint to the target endpoint.
A balanced chemical equation preserves each nuclide or, in ordinary chemical bookkeeping, each element and net charge.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

A net chemical equation is a coarse representation of a mechanism that preserves overall stoichiometry but omits elementary steps, intermediates, rates, and pathway branching.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.

Stoichiometric conservation equations determine admissible coefficient ratios but do not by themselves establish a reaction mechanism.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

This is an authored directed relation from the source endpoint to the target endpoint.
A balanced chemical equation gives the amount ratios used to identify a limiting reactant, but it does not by itself establish reaction completion or exclude competing pathways.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
