i think it was made in 1925 but not sure
:)
Antoine Lavoisier: Developed the Law of Conservation of Mass. We don't really know who discovered it. Hope that answered it...:)
albert Einstein
The law of conservation of mass states that the total mass of substances in a closed system remains constant over time, regardless of the changes that occur within the system. This principle was discovered by Antoine Lavoisier, a French chemist, in the late 18th century.
The first modern enunciation is from Mikhail Lomonosov in 1848.
The law of conservation of mass, or the principle of mass conservation was discovered by Antoine Lavoisier. It states that for any system closed to all transfers of matter an energy, the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed.
He came up with the conservation of mass, discovered oxygen and its role in combustion, and came up with the basis of the modern chemical nomenclature. He did many other things, which can be googled.
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.
The laws of conservation of mass and conservation of energy are similar in that both state that the total amount of mass or energy in a closed system remains constant over time. However, the conservation of mass applies specifically to mass, while the conservation of energy applies to energy in its various forms (kinetic, potential, etc.).
Lavoisier discovered it in 1787. But the one who saw, that this is an new element was Jöns Jakob Berzelius in 1824. Another question:Does anybody of you know, how Antoine Lavoisier discovered silicon? With which experiment? Thanks for every answer!
The Law of Conservation of Mass states that matter can be changed from one form into another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass remains constant, but you have to have a constant area of a penis in order for the pure substances to separate.
This postulate is:" Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process. A chemical reaction simply changes the way atoms are grouped together".
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.
