🧠 Dumas Burns the Compound — Kjeldahl Digests It With Acid

Two statements about Dumas's method. Statement I is about the purpose (estimating nitrogen). Statement II is about the chemistry (formation of  with conc ). The second is the trap — it describes Kjeldahl's method, not Dumas's.

The first move is to keep the two methods clearly separated:

- Dumas: burns the compound with  in  atmosphere; nitrogen is collected as  gas and measured by volume.
- Kjeldahl: digests with conc  +  catalyst; n
