antoine laurent lavoisier substance

Two scientists, Carl Scheele of Sweden and Joseph Priestly of England working independently, discovered oxygen. They published their discovery in 1777. Scheele obtained oxygen by heating potassium nitrate and mercuric oxide and called it "Fire Air". Priestley called it "Dephlogisticated Air". ..

Daniel Rutherford, a Scottish Physician, discovered nitrogen in 1772. But it was Lavoisier, who proved that nitrogen is an element and that it was not a supporter of combustion and respiration. He called it 'azote' meaning 'no life'. The name 'Nitrogen' was given to it by Jean ..

Atoms and Molecules - Laws of Chemical Combination With the development of more scientific ideas on elements, compounds and mixtures, people began to probe into how and why substances react. French chemist A. Lavoisier laid the foundation to the scientific investigation of matte..

: an active part, and an inactive part. This discovery was made by John Mayow in 1674. In 1789, Antoine Lavoisier found out that the active and the inactive parts were in the proportion of 1:4 by volume. The active part was later named oxygen, and the inactive part, nitrogen. ..

Origin of Organic Chemistry Carbon compounds are of two types: inorganic and organic. The compounds that have a mineral origin fall under the category of inorganic compounds. The compounds having plant or animal origin are classified as organic compounds. Lavoisier showed tha..

. Lavoisier, a French chemist, was the first to do this on the basis of quantitative studies. He showed that when we heat mercuric oxide it changes into mercury and oxygen. Mercuric oxide is a compound because it decomposes into simpler substances, whereas mercury and oxygen can..
