Answer:
Conservation of Mass
Explanation:
Conservation of Mass -
According to the works of Antoine Lavoisier , he stated that , mass is always conserved in a chemical reaction .
For example ,
carbon reacts with oxygen , it forms carbon dioxide ,
But , by using the principle of conservation of mass ,
mass can not created or be destroyed , hence , the mass of the initial state and final remains constant , there is only the transfer of mass or matter .
