In the law of conservation of mass (or matter), the mass in a system that is closed will be constant. This holds despite what occurs inside the system. If a candle is burned, the mass of the candle disappears. But the mass is still around in the form of combustion products. For a long time, this idea was presented in the form "matter can neither be created nor destroyed" but only changed (rearranged). In the contemporary age now that relativity and quantum mechanics have taken center stage and shouldered aside the ideas of classical physics, we have to modify the law to allow for the conversion of mass to energy. But classical mechanics still finds broad (and correct!) application in chemistry, and also in the areas of mechanics and fluid dynamics.
Alternate Answer: The current Law of Physics is the Conservation of Mass and Energy, where mass and energy can be changed in form but not created of destroyed. According to Linus Pauling's 'Chemistry' book an atomic bomb converts mass to energy according to the formula E=MC^2. In fact, he says, the measured amount of energy produced in test reactions is about 1.6% of this amount. Each type of nuclear bomb with different materials seems to have a different conversion rate. The Laws of Physics prior to this combined law were the two laws the 'Conservation of Energy' and the 'Conservation of Mass' where each were considered immutable at that time. Note that none of these Laws provide for the creation of matter or energy outside of this convervatism. Neither do they provide for the ultimate destruction of matter and energy.
Matter cannot be created or destroyed; only rearranged.

∙ 14y agoThe law of conservation of mass/matter, also known as principle of mass/matter conservation is that the mass of a closed system will remain constant over time, regardless of the processes acting inside the system. A similar statement is that mass cannot be created/destroyed, although it may be rearranged in space, and changed into different types of particles. This implies that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products. This is also the main idea of the first law of thermodynamics

Which scientific law predicts that the mass of the reactants before a chemical reaction will equal the mass of the products after the reaction has taken place?
Law of Conservation of Mass (aka Law of Conservation of Matter)
What is balancing a chemical equation so that the same number of atoms of each element is found in both the reactants and the products is an example of what?
the law of conservation of matter (or mass)
What law states that the total mass of the reactants always equals the total mass of the products?
The law of conservation of mass. We now know that technically it's not quite true, but it's so close that the difference cannot be detected on the most sensitive balances we have.
When wood is burned in a closed container its mass does not change law theory or observation?
That is a law, specifically the law of conservation of mass. This states that matter can neither be created nor destroyed in a chemical change. This was proved in Lavosier's experiment where he determined that the total lass of the products formed by burning were equal to the mass of the matter burned and oxygen consumed.
What law of conservation says atoms are neither lost nor gained during a chemical reaction?
Law of Conservation of Matter.
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
What law represents a balanced chemical equation?
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.
Why is the law of conservation of mass so similar to the law of conservation of matter?
Answer the question...
Law of conservation of mass is known as law of indestructibility of matter why?
If matter were destroyed, then it would not be conserved. "Conservation" means that the amount of mass doesn't change.
What states that matter is not created or destroyed in a chemical reaction?
You are confusing the law of conservation of matter/mass with the law of conservation of energy. The law of conservation of matter/mass states that in a closed system matter is neither created nor destroyed. During a chemical reaction matter is rearranged, it doesn't change forms (energy can change forms). The atoms in the products are the same atoms that were in the reactants.
What are some alike things to the law of conservation of matter?
There is the law of conservation of mass, and the law of conservation of energy. All three state: (Mass/Matter/Energy) cannot be created or destroyed, simply transferred.
Which scientific law predicts that the mass of the reactants before a chemical reaction will equal the mass of the products after the reaction has taken place?
Law of Conservation of Mass (aka Law of Conservation of Matter)
What scientific law is satisfied when balancing equations?
Law of Conservation of mass(atomic mass). As mass can be considered relative to energy, therefore Law of Conservation is also correct but Law of conservation of mass is is much more accurate because here mass is a much more accurate term that is required here. Here, since, we are balancing molecules, then we require atomic or molecular mass.

The law of conservation of mass. We now know that technically it's not quite true, but it's so close that the difference cannot be detected on the most sensitive balances we have.
The principle stating that matter is not created or destroyed during a chemical reaction?
law of conservation of mass
Why is the law of conservation of mass used and give Background of the law of conservation of mass?
There is no law of concervation of mass anymore, it is the law of conservations of energy (since mass can be converted into pure energy, thank you Albert).
