State the law of conservation of mass. Give one example to illustrate

1.	State the law of conservation of mass. Give one example to illustrate this law.
Answer» Antonie Lavoisier proposed the Law of conservation of mass which states that ‘Mass can be neither created nor destroyed’ so in a chemical reaction, the total mass of reactants must be equal to the total mass of products. For example: 100gs of calcium carbonate decomposes to produce 56gms of calcium oxide and 44gms of carbon dioxide Mass of reactant = 100gm Mass of Product = 56+44gm = 100gm Since mass of the reactant is equal to the mass of the product, there is no change in the chemical reaction.

Answer»

Antonie Lavoisier proposed the Law of conservation of mass which states that ‘Mass can be neither created nor destroyed’ so in a chemical reaction, the total mass of reactants must be equal to the total mass of products.

For example: 100gs of calcium carbonate decomposes to produce 56gms of calcium oxide and 44gms of carbon dioxide

Mass of reactant = 100gm

Mass of Product = 56+44gm = 100gm

Since mass of the reactant is equal to the mass of the product, there is no change in the chemical reaction.
