How did Antoine Lavoisier discovered the law of conservation of mass?
How did Antoine Lavoisier discovered the law of conservation of mass?
Lavoisier carefully measured the mass of reactants and products in many different chemical reactions. He carried out the reactions inside a sealed jar, like the one in the Figure below. In every case, the total mass of the jar and its contents was the same after the reaction as it was before the reaction took place.
What did Antoine Lavoisier discover and what year?
Antoine Lavoisier was well known for his understanding of finance, biology, chemistry and economics. In 1778 he stated the law of conservation of mass and recognized oxygen. In 1783 he recognized hydrogen, introduced the metric system and reformed element nomenclature.
What did Antoine Lavoisier discover 1777?
In 1777 Lavoisier correctly identified sulfur as an element. He had carried out extensive experiments involving this substance and observed that it could not be broken down into any simpler substances.
What is Antoine Lavoisier best known for?
Antoine-Laurent Lavoisier, a meticulous experimenter, revolutionized chemistry. He established the law of conservation of mass, determined that combustion and respiration are caused by chemical reactions with what he named “oxygen,” and helped systematize chemical nomenclature, among many other accomplishments.
What year did Lavoisier state his ideas about the law of conservation of mass?
The ancient Greeks first proposed the idea that the total amount of matter in the universe is constant. However, Antoine Lavoisier described the law of conservation of mass (or the principle of mass/matter conservation) as a fundamental principle of physics in 1789.
How did Lavoisier transform the field of chemistry in the late 1700s?
How could Antoine Lavoisier The French scientist credited with proposing the law of conservation of matter have demonstrated this law?
Antoine Lavoisier is credited with proposing the law of conservation of matter. He performed experiments where he meticulously measured the masses of reaction reactants and products in a sealed system, so that no gas could escape.
Who discovered air?
About Joseph Priestley Some 2,500 years ago, the ancient Greeks identified air — along with earth, fire and water — as one of the four elemental components of creation.
What were the challenges of Antoine Lavoisier?

What law is based on the experiment of Lavoisier?
The Law of Conservation of Mass (or Matter) in a chemical reaction can be stated thus: In a chemical reaction, matter is neither created nor destroyed. It was discovered by Antoine Laurent Lavoisier (1743-94) about 1785. However, philosophical speculation and even some quantitative experimentation preceeded him.
How did Antoine Lavoisier discover the law?
Dismantling phlogiston theory. Lavoisier’s chemical research between 1772 and 1778 was largely concerned with developing his own new theory of combustion.
