Because water is a compound and Hydrogen and oxygen are its constituents and after forming the compound the chemical properties of its constituents changes

Please Try Again 7 years, 7 months ago

Actually water is a compound of hydrogen and oxygen and compounds have different properties from those of their inclusive elements, it blocks oxygen and reduces temperature of burning substance so it is used as fire extinguisher

Because in case of water there is not only hydrogen atom ... it is attached with oxygen due to which some changes in properties of both takes place ..

According to Heisenberg's uncertainty principle it is not possible to find accurate value of position and velocity of an atom at a time because to find velocity or position we must give it some energy and due to this energy one of its factor will change at the same time . So ... it is not possible to find position and velocity at a same time but according to Bohr ... it was possible to find the value of position and magnitude but he can't explain its reason . That's why bohr 's model proved to be wrong .. ??☺☺.. hope it will help you
