Answer

A French chemist, Antoine Lavoisier, who is known as the father of modern chemistry, changed chemistry from a qualitative to a quantitative science. He proved that the mass of the products in a chemical reaction is equal to the mass of the reactants. Law of conservation of mass states that any mass given in a closed space remains the same regardless of whatever is done on or with it. It can neither be created nor be destroyed in a closed isolated system, just like energy.

Answer

Antoine Lavoisier

Antoine Lavoisier, a French chemist, is credited with formulating the law of conservation of mass. He proposed this fundamental principle in the late 18th century. Lavoisier is often referred to as the 'father of modern chemistry' due to his significant contributions to the field.

The Law of Conservation of Mass

Lavoisier's law of conservation of mass states that 'mass is neither created nor destroyed in a chemical reaction.' In other words, the total mass of the reactants in a chemical reaction is equal to the total mass of the products formed.

Experimental Evidence

Lavoisier conducted numerous experiments to support his law of conservation of mass. One of his most famous experiments involved the reaction between mercury and oxygen. He observed that when these two substances combined, they formed a new substance known as red oxide of mercury. Lavoisier meticulously measured the mass of the reactants before and after the reaction and found that the total mass remained unchanged. This experiment and others like it provided compelling evidence for the law of conservation of mass.

Significance

The law of conservation of mass has profound implications for the field of chemistry. It forms the basis for stoichiometry, which involves the quantitative relationships between reactants and products in a chemical reaction. By applying this principle, chemists can accurately predict the amounts of substances involved in a reaction.

The law also supports the concept of atomic theory. Lavoisier's experiments demonstrated that substances combine in fixed ratios by mass, which laid the groundwork for understanding chemical reactions at the atomic level.

Impact on Scientific Progress

Lavoisier's law of conservation of mass revolutionized the field of chemistry and paved the way for many subsequent discoveries. It challenged the prevailing theories of phlogiston and opened up new avenues of research. By establishing the concept of mass conservation, Lavoisier transformed chemistry into a quantitative science.

In conclusion, Antoine Lavoisier is the scientist who gave the law of conservation of mass. His groundbreaking work and meticulous experiments provided the experimental evidence needed to support this fundamental principle. The law of conservation of mass has had a lasting impact on the field of chemistry, enabling precise calculations and contributing to our understanding of chemical reactions.
