If matter were destroyed, then it would not be conserved. "Conservation" means that the amount of mass doesn't change.
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
The best example of the law of conservation of matter is complete combustion. If you were to burn something of known mass in a closed system, the system would have the same mass before and after combustion occurs.
In both cases, something is conserved - it doesn't change over time.Also, mass and energy are equivalent. If something has energy, it has mass, and vice versa.
The mass of reactants is equal to the mass of products.
In a chemical reaction, the amount of matter remains the same. This is known as the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction; it can only be rearranged.
The law of conservation of matter is also known as the law of conservation of mass. It states that mass is neither created nor destroyed in a chemical reaction, only rearranged.
This fact is called the conservation of mass.
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
The law of conservation of mass, also known as the principle of mass conservation or Lavoisier's principle, states that matter is neither created nor destroyed in a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products in a closed system.
During chemical processes in a closed system the mass remain constant.
According to the principle of conservation of mass-energy, matter and energy cannot be created or destroyed, only transformed from one form to another. This is a fundamental concept in physics known as the law of conservation of mass-energy.
The principle that states matter cannot be created nor destroyed is the law of conservation of mass. This scientific principle is also known as the law of conservation of matter. It states that in a closed system, the total mass remains constant before and after a chemical reaction or physical change.
The law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed, it can only change form. This means that in a chemical reaction that takes place in a closed system, the mass of the reactants equals the mass of the products.
Dalton's 2nd atomic theory law is that matter cannot be created nor destroyed. But consider the burning of a coal in oxygen, it appears that matter has been destroyed bcoz de mass of ash obtained at de end of burning is far less than the mass of coal and oxygen b4 burning. Eistein derived an expression 2 de interconversion of matter nd energy gven by E=mc(square), wia c is de velocity of light nd E energy and m is de mass. The theory has now been put in the form of law called de LAW OF CONSERVATION OF MASS or de law of indestructibility of matter. THE LAW OF CONSERVATION OF MASS STATES THAT MATTER CAN NIETHER BE CREATED NOR DESTROYED IN THE COURSE OF CHEMICAL REACTION.
It may also be known as the law conservation of mass; and it states that the total mass of materials present after a chemical reaction is the same as the total mass before the reaction. This law is the basis for Dalton's postulate 3.
that is the Law of Conservation of Matter.
