What did lavoisier contribute to the periodic table?
In 1789 Lavoisier published his Elementary Treatise of Chemistry in which he identified oxygen, nitrogen, hydrogen, phosphorus, Mercury, zinc and sulphur as substances which could not be broken down further - that is, they were identified as elements.
How did Antoine Lavoisier say substances should be named?
by mass
Which scientist showed that the total mass of the substances in a chemical reaction is always the same before and after the chemical reaction?
Antoine Lavoisier
Who developed the modern system of naming substances based on their compositions?
Antoine Lavoisier
How does Lavoisier expose a mouse to a gas he collected from the mercury?
Why do you think lavoisier exposed a mouse to the gas he collected from mercury

How did lavoisier distinguish between compounds and elements?
he used the amount of atoms in each element and compound.
Who classified elements?
lavoisier.
What is the for the reaction that breaks substances into their basic elements?
The reaction that breaks substances into their basic elements is called a decomposition reaction. Modern chemistry is said to have started when an 18th century Frenchman, LaVoisier, heated a gray ore and got mercury and oxygen out of it! The first recognized decomposition reaction.

Who classified elements into four categories?
Antoine Lavoisier
Lavoisier made an important contribution to chemistry by?
- Lavoisier, independently from Lomonosov, emitted the law of mass conservation- Lavoisier constated the first that combustion is a raction with oxygen- Lavoisier was a proter of the metric system units- Lavoisier written a list of chemical elements- Lavoisier fighted against the theory of phlogiston- Lavoisier had contributions to the chemistry of oxygen, hydrogen, sulfur, silicon, phosphorus, carbon dioxide- Lavoisier discovered that diamond is carbon- Lavoisier worked for a rational nomenclature in chemistryetc.
What are the simplest substances cannot be broken down into any other substances?
You think to atoms of chemical elements.
Who developed the modern system of naming substances based on their compositions?
Antoine Lavoisier
What is stoichiometry all about?
Stoichiometry is about the Lavoisier's principle on the conservation of mass and elements in chemical reactions.[Cf. Related links on A. Lavoisier, below this answer]
Why did lavoisiers classification fail?
Lavoisier's classification system failed because it was based on the elemental theory that all substances are composed of earth, air, fire, and water, which was later proven incorrect. Additionally, Lavoisier's system did not account for the wide variety of elements that were discovered after his time, leading to inaccuracies and limitations in classification.
