Question

1. State law of conservation and its limitations. (3 ​points)​

Answer 1

Answer:

Explanation:

First of your question doesn't defined which conservation law you are talking about

Is it law of conservation of energy or mass or momentum etc

I'm giving ans here with respect to law of conservation of mass

Law of conservation of Mass:

The total mass of the products must be equal to the total mass of the reactants in any physical or chemical change

Limitation

1. In a nuclear reaction, some the mass gets converted into energy creating an imbalance between the mass of reactants and the products. Therefore, the total mass is not conserved. This is the limitation of the conservation of mass.
2. The other limitation of conservation of mass is according to Einstein’s theory, the relation between two quantities is given by E = mc2, which means that energy and mass are interconvertible. Therefore, for the law of conservation of mass to be valid mass and energy of the system must be conserved.

Answer 2

Answer:

We know from the definition of the law of conservation of mass that the total mass of the products must be equal to the total mass of the reactants in any physical or chemical change. If the reactants are less or more in than the products, total mass is not conserved, so the reaction is "wrong". This is the limitation of the conservation of mass.
