from the law of definite proportion which means that if 1gram of hydrogen and 8gram of oxygen are combined together then water will form. water is form due to fixed composition of hydrogen and oxygen. the two atoms of hydrogen is taken and one atoms of oxygen is taken to form water.

hey friend
H20 cant mean HO2.
case 1- H2O tells that there are two atoms of hydrogen combined with oxygen.
case 2 - HO2 tells that there are two oxygen atoms combined with only one atom of hydrogen.
case 2 can't exist because the oxygen has 6 electrons in its outermost shell and it needs only 2 atoms of 1 valency to combine with it.
so two hydrogens come in giving us H20 not H02.
hope u understand now.. :)
