How does the total mass of the products of a chemical reaction compare with the total mass of the reactants?

How does the total mass of the products of a chemical reaction compare with the total mass of the reactants?

The law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. Because atoms are rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products.

How does the total mass of the substances formed as a result of a chemical change compare with the total mass of the original substances?

In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.

What does the law of conservation of mass tell us about the total amount of matter?

History of the Law of the Conservation of Mass The ancient Greeks first proposed the idea that the total amount of matter in the universe is constant. This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system.

What law states that the total mass of the reactants equals the total mass of the products in a chemical reaction?

the law of conservation of mass
One of these is called the law of conservation of mass , which states that during a chemical reaction, the total mass of the products must be equal to the total mass of the reactants. In other words, mass cannot be created or destroyed during a chemical reaction, but is always conserved.

What is the final mass of the products based on the law of conservation of mass?

The Law of Conservation of Mass 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.

How is the law of conservation of mass demonstrated in a chemical equation?

Following the Law Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

What does the law of conservation of mass state quizlet?

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations.

Why is the mass of a chemical reaction always the same?

In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants. This law was later amended by Einstein in the law of conservation of mass-energy, which describes the fact that the total mass and energy in a system remain constant.

How does the law of Conservation of mass work?

According to the law of conservation of mass, in a chemical reaction the total starting mass of all the reactants equals the total final mass of all the products.

Who was the first scientist to discover the law of Conservation of mass?

Antoine LavoisierA portrait of Antoine Lavoisier, the scientist credited with the discovery of the law of conservation of mass. This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system.
