  • A.Hund's rule
  • B.Dalton's law
  • C.Avogadro's law
  • D.Berzelius hypothesis

Dalton's atomic theory explains the conservation of mass.

Its postulate is that atoms are indivisible and are neither created nor destroyed in a chemical reaction; a reaction only rearranges them. Since the same atoms are present before and after, the total mass cannot change.
