The law of conservation of mass / matter, also known as the law of mass / matter conservation (or the Lomonosov-Lavoisier law), states that the mass of aclosed system of substances will remain constant, regardless of the processes acting inside the system.
An equivalent statement is that mattercannot be created nor destroyed, although it may change form. This implies that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products.
The law of mass / matter conservation may be considered as an approximate physical law that holds only in the classical sense before the advent of special relativity and quantum mechanics. This historical concept is widely used in many fields such as chemistry, mechanics, and fluid dynamics. However, mass is not conserved in nuclear reactions. The law of conservation of mass was first clearly formulated by Antoine Lavoisier in1789. However, Mikhail Lomonosov(1748) had previously expressed similar ideas and proved them in experiments.

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.
Which law physical science must be followed when balancing chemical equations?
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 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.
How does Dalton atomic theory explain the law of conservation of mass?
Dalton doesn't explain 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.
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.
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
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.
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)
Which law physical science must be followed when balancing chemical equations?
the law of conservation of mass
Which scientist first proposed the law of conservation of mass?
M. Lomonosov and A. Lavoisier are credited for the enunciation of the law of conservation of mass: but many other were involved in this discovery, from the antiquity to XIXth century and this case is common for many discoveries.
How this law was created law of conservation of mass?
it conserves mass
In what situations would mass be conserved?
This is a general law of nature - the law of mass conservation.
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 dose law of conservation of mass?
The Law of Conservation of Mass is the concept that mass cannot be created or destroyed, it simply changes form.
