Type your answer here... The hydrogen atoms in heavy water have a neutron in the nucleus, doubling the mass.
Heavy water is chemically the same as regular (light) water, but with the two hydrogen atoms (as in H2O) replaced with deuterium atoms (hence the symbol D2O). Deuterium is an isotope of hydrogen. it has one extra neutron.
The hydrogen atoms in heavy water have a neutron in the nucleus, doubling the mass.

Water that contains hydrogen-2 instead of hydrogen-1 is called heavy water.
Short answer: Yes. Technically correct answer: Depends on the water. Hydrogen is an element defined by having 1 proton. However elements can have different numbers of neutrons and still be the same element, but be a different isotope. 'Normal' hydrogen is called protium and has no neutrons. If it has 1 proton it's deuterium, and 2 tritium. These occur naturally but in low amounts, and can be found in water. If the concentration of deuterium is high its called heavy water. So in this sense, not all the hydrogen atoms would be the same; there would be 3 types (more than 3 protons is unstable on only produced in a lab, and won't last long) Depending on question: if you were actually asking "are the hydrogen atoms in water identical to the hydrogen atoms you find in other molecules?" Then yes (taking into account isotopes, the profound atoms in water molecules are the same as elsewhere). That is to say, they are interchangable. Note: Only their nuculei would be identical, what the electrons get up to will be different, but the important thing is they are interchangeable.
Hydrogen and oxygen are both gases at room temperature, while water is a liquid at room temperature.
A hydrate is a compound that has to contain water, when other chemical compounds can be composed of anything. People this is SO easy. KNOW YOUR FREAKIN FACTS!
Hydrogen is water...which can also produce electricity by the water wheel....Basically hydrogen is water..Theres nothing difficult about WATER/HYDROGEN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Heavy water is water whose atomic structure consists of oxygen and heavy hydrogen. Heavy hydrogen, or deuterium, is hydrogen with neutrons in its nuclei.
Normal water is made of H2O. That is: two hydrogen atoms and one oxygen atom. Heavy water is made of 2H2O (also known as D2O). That is: one deuterium atom and one oxygen atom. Deuterium is a variation of hydrogen which has a neutron in its nucleus (normal hydrogen has no neutrons). Do not confuse heavy water with H2O2, which is simply hydrogen peroxide.
Normal Water (H20) has hydrogen atoms with one proton and Heavy Water (D20) has a neutron and a proton in it H2 atoms.
heavy water can be seperated by exchanging the D20 between ordinary water and hydrogen sulphide at different temperatures
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).
Heavy water can be used to make titanium. Titanium is used to make many things, from jewelery to automobiles and self-powered lighting. Titanium is becoming a more common substance, as it is incredibly tough.
Heavy water is not an isotope. It is the compound H2O, same as water, except that the "normal" hydrogen atoms H-1 are replaced by atoms of deuterium = H-2.
Heavy water is about 11% denser than ordinary water, due to enriching of its deuterium isotopes.
Heavy water is not an isotope. It is the compound H2O, same as water, except that the "normal" hydrogen atoms H-1 are replaced by atoms of deuterium = H-2.
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.
Since heavy water contains an isotope of hydrogen 2H or more commonly called Deuterium means that the hydrogen atom in heavy water will have an extra neutron in the nucleus.
Water that contains hydrogen-2 instead of hydrogen-1 is called heavy water.
