matter is neither created nor destroyed (this is not 100% true but for most purposes the specifics are unnecessary)
If by the law of conservation you mean the Law of Conservation of Matter, then it states that matter cant be created or destroyed.
If by the law of conservation you mean the Law of Conservation of Matter, then it states that matter cant be created or destroyed.
The law of conservation of matter is applied to processes not to a compound.
Answer the question...
The law of conservation of matter is also known as the law of conservation of mass. It states that mass is neither created nor destroyed in a chemical reaction, only rearranged.
The law of conservation of matter
The law of conservation of matter states that in a chemical reaction, matter is neither created nor destroyed.
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.
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.
This is the Law of Conservation of Matter.
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
