Antoine Lavoisier publishes Traité Élémentaire de Chimie, the first modern chemistry textbook. It is a complete survey of (at that time) modern chemistry, including the first concise definition of the law of conservation of mass, and thus also represents the founding of the discipline of stoichiometry or quantitative chemical analysis.

On a nearby tree, a metal plaque was placed, asserting the claims of France and stating that the tablet lay nearby. This practice of burying plates first began in Europe in the Middle Ages and was a common way to show land ownership. In total, De Bienville is believed to have buried six plates. Only one has been found intact. [2]
1669 – René-Robert Cavelier, Sieur de La Salle discovers the Ohio River, descending it as far as the Falls of the Ohio near the site of modern Louisville, Kentucky. [ 73 ] 1673 – French-Canadian explorer Louis Jolliet and Jesuit missionary Jacques Marquette reach the upper Mississippi River , descending it to its confluence with the ...
In 1849 he discovered anhydrous nitric acid (nitrogen pentoxide), a substance interesting as the first obtained of the so-called "anhydrides" of the monobasic acids. In 1854, he succeeded in obtaining metallic aluminium , and ultimately he devised a method by which the metal could be prepared on a large scale by the aid of sodium , the ...
Tanks : developed at the same time (1915–1916) in France and in Great Britain. France was the second country to use tanks on the battlefield (after Great Britain). in 1916, the first practical light tank, the Renault FT with the first full 360° rotation turret became, for armour historian Steven Zaloga "the world's first modern tank".

A 100,000-year-old ochre-processing workshop was found at Blombos Cave in South Africa. It indicates that early humans had an elementary knowledge of mineral processing. Paintings drawn by early humans consisting of early humans mixing animal blood with other liquids found on cave walls also indicate a small knowledge of chemistry. [3] [4]
Antoine-Laurent de Lavoisier (/ l ə ˈ v w ɑː z i eɪ / lə-VWAH-zee-ay; [1] [2] [3] French: [ɑ̃twan lɔʁɑ̃ də lavwazje]; 26 August 1743 – 8 May 1794), [4] also Antoine Lavoisier after the French Revolution, was a French nobleman and chemist who was central to the 18th-century chemical revolution and who had a large influence on both the history of chemistry and the history of biology.
Lavoisier clearly ties his ideas in with those of Condillac, seeking to reform the field of chemistry. His goal in Traité was to associate the field with direct experience and observation, rather than assumption. His work defined a new foundation for the basis of chemical ideas and set a direction for the future course of chemistry. [18]
