How do you know that mass is conserved in a chemical reaction?

Question

Responses

The mass of the reactants is the same as the mass of the products.
The mass of the reactants is the same as the mass of the products.

The mass of the reactants is greater than the mass of the products.
The mass of the reactants is greater than the mass of the products.

The mass of the reactants is less than the mass of the products.
The mass of the reactants is less than the mass of the products.

The mass of the reactants is different from the mass of the products.

Answer 1

The correct response is:

The mass of the reactants is the same as the mass of the products.

This statement aligns with the law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed during a chemical reaction. Therefore, the total mass of the reactants must equal the total mass of the products.
