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 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.
Can you revise a scientific law?
Scientific laws can be revised, although that doesn't happen very often. New observations and new analyses of observations can lead to revisions of theories, including the laws that are contained in those theories. An example of this concerns the law of conservation of mass. This law still applies in its original form to chemical reactions, but it has also been discovered that due to the mass-energy equivalency that was first described by Einstein, mass is not always conserved, and a better formulation of the law is that mass-energy is conserved.
How did John Dalton explain a chemical reaction using his atomic theory?
Three laws during Dalton's time were the law of definite proportions, law of multiple proportions and law of conservation of mass. According to law of conservation of mass, there is no loss of mass during any chemical reaction. Dalton's proposition that atoms are not destroyed or invented. The atoms merely realign themselves in a chemical reaction; so there is no loss of mass. According to the law of multiple proportions, when 2 elements form more than 1 compound, the different masses of one element that combine with the other element are connected to each other in small whole ratios. For example, in the case of nitrogen dioxide and nitrogen monoxide. One atom of nitrogen combines with one atom of oxygen for nitrogen monoxide. One atom of nitrogen combines with two atoms of oxygen for nitrogen dioxide. In the case of law of definite proportions, it is stated that a chemical compound always has precisely the same proportion of elements in terms of mass. According to Dalton's atomic theory, matter consists of atoms and one type of atom is allocated for each element. Compounds were actually combinations of various kinds of atoms in fixed ratios.
Is it true that The Law of Conservation of Mass states that in a chemical reaction matter can be created or destroyed?
true false is not correct
What does the principle of conservation of matter means?
A citation from Wikipedia:"The law of conservation of mass, also known as principle of mass/matter conservation is that the mass of a closed system (in the sense of a completely isolated system) will remain constant over time."For more details see the link bellow.
Do chemical reactions describe laws of conservation?
Chemical reactions respect the law of mass conservation.
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.
How is the low of conservation of mass related to chemical reactions?
The Law of Conservtion of Mass is essential in all chemical reactions. "related to chemical reactions" is a foolish statement, because the words are "essential", "required", and "fundamental".
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.
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.
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.
What chemical reactions have a conservation of?
You think probable to the law of mass conservation.
How does the of the conservative of mass apply to chemical reactions?
The law of conservation of mass states that in a close container, when a chemical reaction occurs, no mass will be lost.
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.
How does the law of the conservation of mass apply to to chemical reactions?
Atoms cannot be added or lost in a chemical reaction.
Conservation in a sentence?
The law of Conservation of Mass states that in ordinary chemical reactions, mass can not be created or destroyed.
How can you use the law of conservation of mass to help you balance a chemical equation?
because the total mass of the reactions in a chemical reaction is the same as the total mass of the products.
