Well, regular water is H²O, but since oxygen always wants to be O². Therefore it breaks down to H²O, but it's really H²+² O²
How to explain heavy water?
Heavy water, D2O, is water in which both hydrogen atoms have been replaced with deuterium, the isotope of hydrogen containing one proton and one neutron. It is present naturally in water, but in only small amounts, less than 1 part in 5,000. Heavy water is one of the two principal moderators which allow a nuclear reactor to operate with natural uranium as its fuel. The other moderator is reactor-grade graphite (graphite containing less than 5 ppm boron and with a density exceeding 1.50 gm/cm 3 ). The first nuclear reactor built in 1942 used graphite as the moderator; German efforts during World War II concentrated on using heavy water to moderate a reactor using natural uranium.
The importance of heavy water to a nuclear proliferator is that it provides one more route to produce plutonium for use in weapons, entirely bypassing uranium enrichment and all of the related technological infrastructure. In addition, heavy-water-moderated reactors can be used to make tritium.
Although one speaks of “making” heavy water, deuterium is not made in the process; rather, molecules of heavy water are separated from the vast quantity of water consisting of H2O or HDO (singly deuterated water), and the “dross” is discarded. Alternatively, the water may be electrolyzed to make oxygen and hydrogen containing normal gas and deuterium. The hydrogen can then be liquefied and distilled to separate the two species. Finally, the resulting deuterium is reacted with oxygen to form heavy water. No nuclear transformations occur.

H2O2 is better known as hydrogen peroxide. It is an oxidizer that has many uses.
Heavy water, D2O, is water where the normal hydrogen atoms have been replaced by deuterium, an isotope of hydrogen with an extra neutron in the nucleus. Where normal water, H2O, has a molecular weight of about 18 daltons, heavy water has a molecular weight of 20 daltons (thus the moniker "heavy"). Chemically, deuterium oxide is almost indistinguishable from H2O, but D2O has some advantages as a neutron moderator in nuclear power reactors.
Oh, and by the way, heavy water is toxic, but you'd need to drink pure D2O exclusively for about two weeks to start to suffer the effects.

h2o2 is not water . it is peroxid hydrogen but heavy eater is water , but there is a difference .there is one or two newtron at the cuclieus of hydrogen.

If I remember my college chemistry correctly: H2O2 is hydrogren peroxide and "heavy water", (name starts with "Det..") is D2O.
