Because heavy water is D2O and not H2O; the hydrogen atomic nucleus has only one proton, the deuterium has one proton and one neutron. Consequently the properties of the two isotopes are very different. The deuterated water is more dense than the normal water (1,1056 g/cm3 for D2O and 0,9982 g/cm3 for H2O.

∙ 14y agoThe formula of normal water is H2O, the formula of heavy water is D2O. The atom of hydrogen has only one proton, the atom of deuterium has also a neutron. The mass of deuterium is double compared with the mass of hydrogen. Consequently the density of heavy water is greater.

Is a solution heavier than a solvent?
Depends on the solute: alcohol in water is lighter, salt in water is heavier than water.
Is salt water's density heavier than pure water?
Salt water's density greater (not heavier) than that of pure water.
Is breath heavier than air?

Is Saturn lighter or heavier than water?
it is lighter than water.
What elements are formed in cool stars?
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
Why do heavy objects sink in water?
Objects sink in water because they are denser than water, not necessarily because they are heavier.
Why is deuterated water heavier than water?
Heavy water (D2O) is water created using the Deuterium isotope of Hydrogen, and is about 11% more dense than normal water but is still physically and chemically very similar to regular H2O. Heavy water is commonly used as a nuclear reactor moderator (slow down the neutrons to sustain the fission reaction). see related link
Is Warm air heavier or cold air?
cold air is heavier than the warm air warm air has low water so it is hot and low heavy but cold air has a lot of water so it cold and heavy

What makes gasoline heavier than water?
Gasoliner is NOT heavier than water. If you mix the two compounds , then allow them to settle. You will see that gasoline is on top of the water. ; Hence it is lighter (less heavy). Scieintifically, the density of gasoline is less than the density of water.
How will knowing that ice is heavier than water help you in your life?
ice is not heavier than water
Is sulfuric acid heavier than water?
It is 1.84 times heavier than water.
How is light water light different than heavy water?
Heavy water is heavier than light water because instead of both hydrogen atoms in the molecule being ordinary light hydrogen (H - one proton) one or both hydrogen atoms are heavy hydrogen (D - one proton, one neutron).
Can molten rock float on water?
No. Molten rock is heavier than water.
