2-Law of constant proportion:-it states that the reactants always combine in the fixed ratio of their masses to form compounds , independent of the method of preparation.
3-Law of multiple proportion:-it states that different masses of two elements which combines with the fixed weight of third element bears a simple numerical ratio of their masses.
4-Law of reciprocal proportion:-it states that the masses of two different elements which combines with the fixed weight of third element are either same or bears simple numerical ratio of their masses when they combine with each other.
