Key Points. The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Law of conservation of mass. The law of conservation of mass states that no atoms are lost or made in a chemical reaction. ... The sum of the relative formula masses of the reactants is equal to the sum of the relative formula masses of the products.

noun Physics. the principle that in any closed system subjected to no external forces, the mass is constant irrespective of its changes in form; the principle that matter cannot be created or destroyed.

The Law of Conservation of Matter states that matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products.

A common or traditional definition of matter is "anything that has mass and volume (occupies space)". For example, a car would be said to be made of matter, as it has mass and volume (occupies space).

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity cannot be added nor removed.
1096838
The law of conservation of massstates that mass is neither created nor destroyed. In a closed system, mass of reactants is equal to mass of products. ... the law of conservation of mass states that mas can neither be created nor be destroyed during a chemical change.
420488
The law of Conservation of Energy states that energy cannot be created or destroyed - it can only be transferred from one type to another.
1097616
According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and type of atoms after the chemical change as were present before the chemical change.
72724
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.

Dalton hypothesized that the law of conservation of mass and the law of definite proportions could be explained using the idea of atoms. He proposed that all matter is made of tiny indivisible particles called atoms, which he imagined as "solid, massy, hard, impenetrable, movable particle(s)".
656942
The conservation of matter. In reactions under normal laboratory conditions, matter is neither created nor destroyed, and elements are not transformed into other elements. ... Because matter is not created or destroyed in a chemical reaction, the total mass of reactants is the same as the total mass of products.

Class 9 Chemistry Atoms and Molecules. Laws of conservation of mass. Laws of conservation of mass. The law states that mass can neither be created nor destroyed in a chemical reaction i.e. Total masses of reactants is equal to the sum of masses of products and the masses of unreacted reactants.

Conservation of Angular Momentum. The law of conservation of angular momentum states that when no external torque acts on an object, no change of angular momentum will occur.

In any physical change or chemical reaction, mass is conserved; mass can be neither created nor destroyed. Law of Conservation of Energy. a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to anothe. photosynthesis.

The rocket works because of the law of conservation of linear momentum. The law of conservation of linear momentum is very important in physics. Momentum is defined as the mass of an object times its velocity.

Law of conservation of mass. No atoms are created or destroyed in a chemical reaction. ... This means that the total mass of the products in a chemical reaction will be the same as the total mass of the reactants .
