Fluorine reacts with hydrogen (h) and deuterium (d) to form hydrogen fluoride (hf) and deuterium fluoride (2h1) is an isotope of hydrogen. would a given amount of fluorine react with different masses of the two hydrogen isotopes? does this violate the law of definite proportion? explain. (de), where deuterium
