Lavoisier's Law


β€œIn a chemical reaction, the sum of the masses of reactants is equal to the sum of the masses of products.”

According to this law, in a closed chemical system, whatever the transformation takes place, the mass follows constant.

These statements obey a law of nature. It was discovered by the French scientist Antoine Lavoisierin the late seventeenth century. For this reason, this law became known as Lhey of Lavoisier or Pasta Conservation Law.

His is also the famous phrase: "In nature nothing is lost, nothing is created. Everything is transformed".

Watch:
A reaction between substances A and B turns into C. The mass of substance A is 20g and B is 5g. What is the mass of C?

A + B β†’ C
20g 5g x

So: 20 + 5 = 25g of C

A + B β†’ C
20g 5g 25g

This reaction obeys Lavoisier's Law, where the sum of the masses of the reactants is equal to the sum of the masses of the products.
