WebSo, the mass ratio of hydrogen to oxygen is 2(1):16 = 1:8 in water. This will be the same irrespective of the source or method of formation. WebA water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other. how are gtaw torches rated
