• Referred to as "Father of Modern Chemistry"
• Married to a young, beautiful 13 year old girl
• An author of many books such as "Considerations Generates sur la Nature des Acides"

Things he demonstrated...

A few achievements of Antoine

What about John Dalton?

• With careful measurements, that transmutation of water to earth was not possible
• Air is composed of 2 parts, one of which combines with metals to form calxes
• Air responsible for combustion was also the source of acidity
• Invented the system of chemical nomenclature still largely in use today including names such as sulfuric acid, sulfates and sulfites

• Won a gold medal on lighting the streets of Paris and designed a new method for preparing saltpeter
• Stated the first version of the Law of Conservation of Mass
• Recognized and named Oxygen and Hydrogen
• Changed chemistry from qualitative to quantitative science
• Showed nature is a closed system
• Helped establish modern chemistry
• Made first modern chemical textbook
• Discovered diamond was crystalline form of carbon

• He proposed that all matter is composed of tiny particles in 1806
• He is known for developing the concept of atoms into a scientific theory that has become the foundation of chemistry
• He developed his Atomic Theory with the help from The Law of Conservation of Mass
• He was able to put together atoms that are indestructible, they can rearrange but do not break apart.

Facts

Law of Conservation of Mass

Their Importance Today

• States mass is neither created nor destroyed during chemical reactions, but that it is conserved
• The mass of reactants is equal to the mass of the products
• He discovered this in the year of 1785

• Born on August 26, 1743 in Paris, France to a wealthy family
• Went to college at des Quatre Nations
• Studied science and became a chemist
• Part of group that helped in the French Revolution
• Caused beheading on May 8, 1794

• Dalton's Atomic Theory, the Law of Conservation of Mass, and the Law of Definite Proportions are basic laws that have created a foundation for the study of chemistry
• Without the findings of Lavoisier's, there would have been more difficulty for Dalton' theory and Proust's Law to be discovered

Law of Conservation of Mass

Who was Joseph Proust?

• He was a chemist who conducted several tests on chemical substances
• He discovered that each pure compound has its own characteristic element composition
• His discoveries led to the Law of Definite Proportions, which says that the proportion by the masses of two given elements will always remain the same
