What did Antoine Lavoisier do in 1789?
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.
Where did Antoine Lavoisier find carbon?
Antoine Lavoisier showed that diamonds are a form of carbon in 1772. He burned carefully weighed diamond and carbon samples and showed that both substances produced no water vapor and the same amount of carbon dioxide gas per gram.
What law did Antoine Lavoisier discover?
the law of conservation of mass
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.
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.
When did Antoine Lavoisier discover nitrogen?
The first breakthrough in the study of chemical reactions resulted from the work of the French chemist Antoine Lavoisier between 1772 and 1794.
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).
Who was the first person to discover sulfur?
The credit for discovering sulfur is given to Hennig Brand (1669), however it was identified by Antoine Lavoisier in 1777.
Who was Antoine Lavoisier and what did he do?
Antoine Lavoisier, in full Antoine-Laurent Lavoisier, (born August 26, 1743, Paris, France—died May 8, 1794, Paris), prominent French chemist and leading figure in the 18th-century chemical revolution who developed an experimentally based theory of the chemical reactivity of oxygen and coauthored the modern system for naming chemical substances.
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’…
How did Antoine Lavoisier come up with the name carbon?
Forms of Carbon. Whether diamond or charcoal were burned by the giant lens, the same gas was produced – we now call it carbon dioxide. Lavoisier realized that diamond and charcoal are different forms of the same element. He gave this element the name carbon.
