Question

what is the Law of conservation of mass & By whom , this law was given , and in which year . & explain with 4 examples

Answer 1

Law of Conservation :

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. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system. Lavoisier's finding laid the foundation for modern chemistry and revolutionized science.

Examples :

• The Campfire.
• Burning candle.

Answer 2

Law of Conservation of Mass ::

that mass can neither be created nor destroyed

in a chemical reaction.

also the mass of reactants is equal to mass of products.

MASS OF REACTANTS = MASS OF PRODUCTS.
