Answer 1

A water sample from a lake , ocean , rain or pond must have identical proportional of hydrogen to oxygen.

solution : according to Proust's law of definite proportions, any chemical compound always contains its component elements in fixed ratio. it doesn't matter what the source of this compound and what the method of preparation of it is.

from the above theory, it is clear that the ratio of hydrogen and oxygen must be identical for all samples and that is 1 : 8.

therefore the correct option is (a) identical.
