How did Antoine Lavoisier find sulfur?
In 1772 Lavoisier discovered that when phosphorus or sulfur are burned in air the products are acidic. The products also weigh more than the original phosphorus or sulfur, suggesting the elements combine with something in the air to produce acids. Priestley believed the gas was a particularly pure version of air.
What compound did Lavoisier split What two gasses were formed?
In June 1783, Lavoisier reacted oxygen with inflammable air, obtaining “water in a very pure state.” He correctly concluded that water was not an element but a compound of oxygen and inflammable air, or hydrogen as it is now known. To support his claim, Lavoisier decomposed water into oxygen and inflammable air.
What was Lavoisier major discovery?
What are Antoine Lavoisier’s accomplishments? Antoine Lavoisier determined that oxygen was a key substance in combustion, and he gave the element its name. He developed the modern system of naming chemical substances and has been called the “father of modern chemistry” for his emphasis on careful experimentation.
How was Sulphur discovered?
It was known from prehistoric times and thought to contain hydrogen and oxygen. In 1809, the French chemists Louis-Joseph Gay-Lussac and Louis-Jacques Thenard proved the elemental nature of sulfur. Sulfur, the tenth most abundant element in the universe, has been known since ancient times.
When did Antoine Lavoisier discovered nitrogen?
French chemist, who collected taxes for the government in Paris. In the 1770s he discovered oxygen and nitrogen in air and demolished the phlogiston theory of combustion by demonstrating the role of oxygen in the process. In 1783 he made water by burning hydrogen in oxygen (see Cavendish, Henry).
How did Lavoisier discovered the law of conservation of mass?
Lavoisier carefully measured the mass of reactants and products in many different chemical reactions. 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. This showed that matter was neither created nor destroyed in the reactions.

When was Sulphur discovered?
1777
Antoine Lavoisier recognized it as an element in 1777, although it was considered by some to be a compound of hydrogen and oxygen; its elemental nature was established by the French chemists Joseph Gay-Lussac and Louis Thenard.
Who was the first person to discover sulfur?
In 1823, a German chemist named Eilhard Mitscherlich discovered sulfur’s allotrophy. Sulfur is a chalcogen and non-metal element that is yellow in color.
How did Antoine Lavoisier prove that water is not an element?
Working again with Pierre-Simon Laplace, Lavoisier burned hydrogen with oxygen and found that water was produced, establishing that water is not an element, but is actually a compound made from the elements hydrogen and oxygen. This result astonished many people, because at that time ‘everyone knew’…
When did Antoine Lavoisier publish his treatise on chemistry?
In 1789 Lavoisier published his groundbreaking Elementary Treatise on Chemistry. Aristotle’s elements of earth, water, air, fire and quintessence had been abandoned by medieval alchemists, and Lavoisier now abandoned their tria prima of sulfur, mercury and salt.
How did Antoine Lavoisier come up with the name oxygen?
In 1779 Lavoisier coined the name oxygen for the element released by mercury oxide. He found oxygen made up 20 percent of air and was vital for combustion and respiration. He also concluded that when phosphorus or sulfur are burned in air, the products are formed by the reaction of these elements with oxygen.
