Answer:
1)
- Law of the Conservation of Mass (mass before reaction has to equal mass after reaction)
- Law of Constant Proportions (the ratio mass for the same compound is constant)
2)atomicity
the number of atoms in the molecules of an element.
3) law of conservation of mass.
mass can neither be created nor distroyed
4) law of constant proportion.
a chemical compound always contains exactly the same proportion of elements by mass.
