Abstract
The overall stoichiometry of a reaction having a multistep mechanismcan be derived using methods based on either of the following twoapproaches: elemental-balance or extent of reaction. The extent ofreaction method (ξ method) has been used for many years. We haverecently shown ( J.Chem.Educ. 2000, 77, 188 ) thatintegration of rate equations (the kinetic method) offers analternative to the ξ method using methods that may be more familiarto many chemists. The two methods are, however, equivalent and give thesame results, as pointed out in the Appendix. The elemental-balancemethod is the simplest of the three methods but, as we shall show, itdoes not always give as much information about the system beinganalyzed as do the other two methods. In this paper bothelemental-balance and kinetic methods will be used to derivestoichiometric relationships and the results will be compared. We showthat each method has its advantages and conclude that both methods areuseful in different contexts.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
