The concept has existed since ancient times - even if the exact statement we now think of as "The Law of Conservation of Matter" is of more recent formulation.
An important idea in ancient Greek philosophy was that "Nothing comes from nothing", so that what exists now has always existed, since no new matter can come into existence where there was none before. An explicit statement of this, along with the further principle that nothing can pass away into nothing, is found in Empedocles (ca. 490-430 BCE): "For it is impossible for anything to come to be from what is not, and it cannot be brought about or heard of that what is should be utterly destroyed".
A closer version was stated by Nasīr al-Dīn al-Tūsī (1201-1274) during the 13th century. He wrote that "A body of matter cannot disappear completely. It only changes its form, condition, composition, color and other properties and turns into a different complex or elementary matter"
The principle of conservation of mass as we now think of it was first outlined clearly by Antoine Lavoisier (1743-1794). It has been claimed that Mikhail Lomonosov (1711-1765) had expressed similar ideas during 1748-and proven them by experiments-but this has been challenged. Others who anticipated the work of Lavoisier include Joseph Black (1728-1799), Henry Cavendish (1731-1810), and Jean Rey (1583-1645).
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
The law of conservation of matter is applied to processes not to a compound.
The law of conservation of matter states that in a chemical reaction, matter is neither created nor destroyed.
The law of conservation of matter
If matter were destroyed, then it would not be conserved. "Conservation" means that the amount of mass doesn't change.
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 conservation of Energy-Matter.
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
The law of conservation of matter is applied to processes not to a compound.
Answer the question...
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.
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 matter states that in a chemical reaction, matter is neither created nor destroyed.
The law of conservation of matter
All chemical reactions obey the law of conservation of matter.
