use atomic theory to explain why chemical reactions obey the law of conservation of mass
Answered by bobpursley
matter in the reactants just rearrange themselves into products, it is the same total matter.
Answered by taha
Chemical reactions obey the law of conservation of mass because the total # of atoms of an element in a chemical reaction stays the same, which means that the atoms can't be created or destroyed because the total # of atoms always stays the same. It's Dalton's atomic theory!
