Kuj kom paub, Antoine Lavoisier paub dab tsi?

Lavoisier feem ntau tau sau tseg rau nws qhov kev tshawb pom ntawm lub luag haujlwm oxygen plays hauv combustion. Nws lees paub thiab hu ua oxygen (1778) thiab hydrogen (1783), thiab tawm tsam phlogiston txoj kev xav. Lavoisier pab tsim lub metric system, sau thawj cov npe uas nws kim heev ntawm cov ntsiab lus, thiab pab kho cov tshuaj nomenclature.

Antoine Lavoisier nrhiav tau oxygen li cas?

Xyoo 1779 Lavoisier tau txais lub npe oxygen rau cov khoom tso tawm los ntawm mercury oxide. Nws pom oxygen ua 20 feem pua ntawm huab cua thiab tseem ceeb heev rau combustion thiab ua pa. Nws kuj tau xaus lus tias thaum phosphorus lossis sulfur raug hlawv hauv huab cua, cov khoom tsim los ntawm cov tshuaj tiv thaiv ntawm cov ntsiab lus nrog oxygen.
