The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the ...

The total mass stays the same during a chemical reaction. This is the law of conservation of mass. In both examples, the reactants and products stay in the beaker. The total mass of the beaker and ...

The mass of one substance in a reaction can be calculated if the masses of the other substances are known. For example: copper carbonate decomposes on heating to make solid copper oxide ...

specifically the law of conservation of mass. The image compares a Ditto, which naturally weighs around 4kg, to it ...
