As in all conservation laws, it means that mass (in this case) won't increase or decrease.In chemical reactions there is a stronger law, which can be quite useful: the total number of atoms OF EACH KIND won't change; thus, if at the start of a reaction you have, for example, three carbon atoms, two oxygen atoms, and four hydrogen atoms in total, at the end you'll have the same combination (three carbon, etc.).

∙ 13y agoIt is simple, the law of conservation of mass will apply nearly all the time. If you have any chemical reactions, the mass of the reactants will always equal the mass of the product. However, some exceptions can happen. For instance, in modern physic, there are two types of mass: the relativistic mass and the invariant mass. The invariant mass will be independent of anything else for which it is the amount of matter of something. The relativistic mass, on the other hand, is related to the velocity of the object. Calculation can be complicated for this but as an object get close to speed of light, the mass will tend to be nearly infinite.

∙ 12y agowell it could happen the law cannot be changed but physical and chemical can. It can change and how? by the chage of how much they wiegh it can happen the states will stay the same but weight may not you see not even matter is created nor destroyed but they amount of matter can cange that. You see even chemicals are changed but so does their weight.
And in physical change it is the oppsite because it is physical change in physical change everthing changes weight, sound, how it looks and more it happens i tell you it does.

∙ 10y agoMass is always conserved in all known processes. Specifically in chemistry, "conservation of mass" has an additional meaning. Not only is the total mass conserved, but also the number of each type of atom doesn't change. For example, to convert hydrogen + oxygen to water, the basic reaction would be:
?H2 + ?O2 = ?H2O
where the question marks represent the number of molecules (or moles) of each type that combine. Here, you have to choose the coefficients so that:
1) The total number of "H" atoms on the left and on the right is the same, and
2) The total number of "O" atoms on the left and on the right is the same.
The solution, in this case, is to replace the question marks with 2, 1, 1 in that order - or any multiple thereof.

∙ 13y agoThe total mass is conserved. However, in chemistry, this refers to a stronger law, which is very useful: the total number of each individual kind of atom is conserved. For example, if at the beginning of a reaction there were 5 oxygen atoms, at the end of the reaction there must also be 5 oxygen atoms.
Unless, of course, the atoms decayed to something else by radioactive decay, or spontaneous fission.

∙ 10y agoIn a chemical reaction, the law of conservation of mass means that the products of the reaction must have the same number and kind of atoms as the reactants you start with. This also means that the mass of the products and the reactants will be equal.

∙ 10y agoA short answer is: the mass of reactants is equal to the mass of products. Matter cannot be created or destroyed, but only transformed.
The law is valid in all fields, including chemistry and physics.

Particles of matter are not created or destroyed. What is the name of this law?
This usually called the Law of Conservation of Matter, or sometimes the Law of Conservation of Mass. It applies to ordinary chemical reactions and physical changes, but not to radioactive materials.
The law of conservation of mass is apply to chemical changes?
The law of conservation of mass applies to all chemical reactions with the exception of nuclear reactions. In nuclear reactions, mass is converted to energy to vice versa. Thus, the law of conservation of mass does not apply in these cases.
How mass conserved during chemical and physical changes?
the of conservation of energy states that energy neither is created or destroyed it changes states the of conservation of mass states that mass neither is created or destroyed it only changes state
What law states that the mass can not be lost or gained in a chemical reaction?
The law of conservation of mass states that in a chemical reaction the mass of the reactants must equal the mass of the product.
What does the law of conservation of mass tell about the mass of a reactants and products in a reaction before a chemical reaction and the ass of the products of the mass of products after a chemical?
The law of conservation of mass tells us that the mass of the products will equal the mass of the reactants in a chemical reaction.
What types of changes observe the law of conservation of mass?
All changes, other than some nuclear reactions, must obey the Law of Conservation of Mass. Chemical reactions, physical changes, heating, cooling, and phase changes must obey the Law of Conservation of Mass.
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.
How does law of the conservation of mass apply to chemical reactions?
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
What does law of conservation of mass?
Mass is not created or destroyed in chemical or physical changes.
Particles of matter are not created or destroyed. What is the name of this law?
This usually called the Law of Conservation of Matter, or sometimes the Law of Conservation of Mass. It applies to ordinary chemical reactions and physical changes, but not to radioactive materials.
The law of conservation of mass is apply to chemical changes?
The law of conservation of mass applies to all chemical reactions with the exception of nuclear reactions. In nuclear reactions, mass is converted to energy to vice versa. Thus, the law of conservation of mass does not apply in these cases.
Which is the best summarization of the law of conservation of mass?
Mass is not created or destroyed during chemical or physical changes.
What is the law that states that mass is neither created nor destroyed during chemical reactions or physical changes?
The law of conservation of matter states that matter cannot be created or destroyed in an ordinary chemical reaction.
The law of what and mass applies to chemical reactions?
The law of conservation of matter/mass applies to chemical reactions. This is why chemical equations must be balanced. The matter that goes into a chemical reaction is present in the products of the reaction, but the atoms have been rearranged to form products with new and unique properties different from the reactants.
What happens to mass during chemical and physical changes. explain?
Law of Conservation of Mass: mass can not be created or destroyed, it can only be changed (transformed).
How mass conserved during chemical and physical changes?
the of conservation of energy states that energy neither is created or destroyed it changes states the of conservation of mass states that mass neither is created or destroyed it only changes state
How are the law of conservation of enegry and the law of mass similar?
The Law of conservation of Energy applies to mass as mass is a form of energy, E=mc2.
