Fundamental Chemical laws Flashcards
introduced the concept of phlogiston.
Georg Ernst Stahl
Universal component of fire that came from a Greek word for inflammable.
Phlogiston
In the late 18th century, a French chemist, __________________, made the first breakthrough in the study of chemical reaction.
Antoine Lavoisier
Due to his curiosity about the study of combustion and the concept of phlogiston, he first tried to burn phosphorus and sulfur. In his experiment, both gained weight which resulted in both elements gaining weight.
Lavoisier later on concluded that combustion involves the reaction of a metal or an organic substance to a “common air.”, which he later named…?
Oxygène (Oxygen)
States that matter can neither be created or destroyed
Law of conservation of Mass
Revolvs to the idea that the total mass of the reactants is the same as the total mass of the products.
Law of Conservation of Mass
A french chemist who stated that if a pure compound is broken down into its constituent elements, the masses of the constituents will always have the same proportions, regardless of the quantity or source of the original substance
Joseph proust
In ancient Greek philosophy, the concept of —————————- is an important idea.
“nothing comes from nothing”
Every —————- substance contained a specific amount of phlogiston
combustible
Antoine Lavoisier made the first breakthrough in the study of chemical reaction in…?
Late 18th century.
Lavoisier reacted oxygen with inflammable air, obtaining “water in a very pure state in…?
June 1783
additional: He concluded that water was not an element but a compound of oxygen and inflammable air, or hydrogen as it is now known.
Lavoisier’s famous textbook
Trait lmentaire de Chimie
in every operation, an equal quantity of matter exists both before and after the operation. This concept was also known as the —————
law of conservation of mass
Proponent of law of conservation of mass
Antoine Lavoisier
Proponent of law of constant composition
