(c)The Law of multiple proportions:-If two elements x and y
combine to give two or more compounds then weights of x
which combine with a fixed weight of y, bear a simple ratio
to one another

(d) The Law of Reciprocal proportions:- The weight of two
elements x and y separately combines with a fixed weight of
a third element z are either the same if simple multiples of
the weights of x and y which combine with each other

(e)Law of gaseous volume:- Whenever gases react they always
do so in volume which bear a simple ratio
