What is the law of conservation of mass ...

What is the law of conservation of mass according to chemical equation?

Text Solution

Verified by Experts

1) The total mass of the products = total mass of the reactants.
2) Atom is a smallest particle that takes part in a chemical reaction.
3) It is the atom which accounts for the mass of any sustance.
4) The number of atoms of each element before and after reactions must by same.
5) This is how the law of conservation is existing in the chemical equation.
