This is according to the law of conservation of mass.
- Every chemical reactions obey the law of conservation of mass.
- The law states that "In every chemical reaction, matter is neither created nor destroyed but changed from one form to another".
- In essence, there is no mass loss in a chemical reaction.
- This law is usually shown by the balancing of chemical species on both sides of the equation.
