What Is The Law Of Conservation Of Mass And Who Discovered It?
The Law of Conservation of Mass, which was first established by Antoine Lavoisier in 1789, is a fundamental principle in chemistry. This law states that during any chemical reaction, the total mass of the substances involved remains constant; in other words, mass cannot be created or destroyed. Therefore, the mass of each individual element or compound at the start of a reaction will always equal the mass of the same elements or compounds at the conclusion of the reaction. This principle laid the groundwork for our understanding of how matter behaves in chemical processes and continues to be a cornerstone in the field of chemistry.
How Was The Law Of Conservation Of Mass Discovered?
The discovery of the law of conservation of mass can be attributed to Antoine Lavoisier, who conducted a groundbreaking experiment. In this experiment, Lavoisier placed a burning candle inside a sealed glass jar and closely observed the changes that occurred. As the candle burned and melted, a significant finding emerged: the total weight of the sealed jar and its contents remained constant throughout the entire process. This critical observation provided compelling evidence for Lavoisier’s pioneering theory, ultimately leading to the establishment of the law of conservation of mass, which states that in a closed system, the total mass remains unchanged during chemical reactions.

Antoine Lavoisier (1743- 1794); matter is neither created nor destroyed during a chemical change. The total mass of the reaction products is always equal to the total mass of the reactants (starting materials). The law of conservation of mass is the basis for many chemical calculations.The Law of Conservation of Mass dates from Antoine Lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.One of Lavoisier’s experiments entailed placing a burning candle inside a sealed glass jar. As the wick burned down and the candle melted, the weight of the jar and its contents remained the same, thereby proving his pioneering theory.
