Fundamental laws of chemistry
The law of conservation of mass.
French chemist A.L. Lavoisier late 18th century using the scale has a large number of experiments, of which there are conclusions which has not been known until then. He has heated mercury oxide red color where has solved two products: methyl mercury and gaseous oxygen. With careful measurements he found that the mass of products was equal to the amount of oxide of mercury which had begun. Lavoazie summed up his discovery of the law: During a chemical reaction overall mass remains constant substances.
Gjennan chemist H. Landolt 100 years later with precise measurements, found that for a large number of chemical reactions occur no change in the size of the system after chemical reaction. In other words, according to experiments Landoltit law is okay for 1 to 10 000000. For more accurate measurements to measure this law will not be applied.
