- 4. the importance of weighing
There are several important discoveries from Antoine Laurent Lavoisier who changed the field of chemistry in the late 1700s
The findings include:
- 1. he discovered the naming of the chemical periodic system for the first time on which the naming of the modern periodic system was based
- 2. He put forward the term "oxygen" and stated that air consists of two components namely nitrogen and oxygen.
- And oxygen is what plays an important role in the combustion process of a substance
- 3. He stated the law of conservation of mass.
Experiments carried out by reacting oxygen and mercury in a closed system and produce mercury oxide
And if it is heated it will again produce the same amount of oxygen and mercury
From this experiment, he stated the law that:
In a closed system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.
- 4. Lavoisier's precision in the importance of the weighing process in chemical reactions causes an important basis in the calculation of chemistry for the progress of research in the future
