This law relates rate of reaction with active mass or molar concentration of reactants.
At a given temperature, the rate of a reaction at a particular instant raised to powers which are numerically equal to the numbers of their respective molecules in the stoichiometric equation describing the reaction."
Active mass = molar concentration of the substance
= (number of gram moles at the substance)/(volume in litres)
= (w/M)/V=n/V

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.
Does burning wood violate the law of conservation of energy?
No, nothing can violate the law of conservation of energy, it's a law! Energy can convert to mass, and mass can convert to energy, but the overall total of mass and energy in the universe is constant.
Can mass be lost?
Mass can not be lost. According to the Law of Conservation of Mass, matter can not be created or destroyed.
How does Einsteins equation Emc2 support the law of conservation of energy?
If you consider mass and energy to be equivalent and interchangeable, it does not conflict with the law of conservation of energy. E=mc2 states that energy is mass and mass is energy, so it does not disprove the law of conservation of energy.
Which law states force depend on the mass and acceleration of an object?
no
How is the active mass represented?
Active mass in mole/dm3 is represented by a square bracket [ ].
How is active mass is represented?
Active mass in mole/dm3 is represented by a square bracket [ ].
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 this law was created law of conservation of mass?
it conserves mass
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 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.
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.
What is the law that states that mass can only be changed or moved?
This is the law of conservation of mass.
In what situations would mass be conserved?
This is a general law of nature - the law of mass conservation.
What is the law of Mass states that mass of what you end with in a chemical reaction is the same as the mass of what you start with?
Law of Conservation of Energy
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.
What are the law of conservation of mass as it relates to phase changes?
it is the same as the law of conservation of mass
