Do water and heavy water belong to the same substance?

It is not the same substance, and the hydrogen element in heavy water is heavy hydrogen (containing one neutron).

The hydrogen element in water does not contain neutrons.

However, the physical and chemical properties of heavy water and water are the same.

Water and heavy water have similar chemical properties but different physical properties, so they are not the same substance.

Yes, it's all water.

But water is made up of the elements hydrogen and oxygen.

Heavy water is made up of deuterium and oxygen.

Deuterium is one more neutron on a hydrogen atom.

Water can be electrolyzed, but heavy water cannot be electrolyzed.

Different disciplines have some different names for water:

According to the different water quality, it can be divided into:

Soft water: Water with a hardness of less than 8 degrees is soft water.

Hard water: Water with a hardness higher than 8 degrees is hard water. Hard water will affect the effect of the detergent, and hard water heating will have more limescale.

According to the content of sodium chloride, drinking water can be divided into:

Fresh water. Salt water.

In addition, there are: biotic water: water in different states that exist in various living systems.

Natural Water: Soil Water: Water stored in the soil.

Groundwater: Water stored in the ground.

Ultrapure water: water with extremely high purity, mostly used in the integrated circuit industry.

Crystal water: also known as hydrated water. In a crystalline substance, a certain number of water molecules are bound to ions or molecules by chemical bonding force.

The chemical formula of heavy water is D2O, and each heavy water molecule is made up of two deuterium atoms and one oxygen atom. Heavy water accounts for less than 2/10,000 of natural water, and the heavy water obtained by electrolysis of water is more expensive than **. Heavy water can be used as a moderator and heat carrier for atomic reactors.

The chemical formula of superheavy water is T2O, and each heavy water molecule is composed of two tritium atoms and one oxygen atom. Excess weight water is extremely scarce in natural water, at less than one part per billion. The cost of producing super-heavy water is 10,000 times higher than that of heavy water.

The chemical formula of deuterated water is HDO, and each molecule contains one hydrogen atom, one deuterium atom, and one oxygen atom. Not very useful.

Yes, the so-called heavy water is nothing more than the hydrogen atom in the water molecule is heavy hydrogen (a hydrogen atom with a neutron in the nucleus), which is slightly larger than the relative molecular mass of ordinary water molecules, but the molecular structure and constituent elements of the two spring deficients are the same, so they are the same substance. Graphite and diamond are different substances because their atomic structures are different.

Heavy water is a compound composed of deuterium and oxygen. The molecular formula D2O, relative molecular mass, is about 11% higher than the relative molecular weight of water (H2O), so it is called heavy water. In natural water, the content of heavy water accounts for about that.

Since the properties of deuterium and hydrogen differ very little, heavy water and ordinary water are also similar. The ionic product constant of heavy water is.

Ordinary water is composed of two hydrogen atoms with only protons and one oxygen 16 atom, but the two hydrogen isotopes in the heavy water molecule are each one volt more neutron than the ordinary hydrogen atom, so the mass of the heavy water molecule is heavier than that of ordinary water. In nature, heavy water is found in very little amount.

Heavy water is similar to ordinary water in appearance, except that the density is slightly higher, gram cubic centimeters, and the freezing point is slightly higher, is, the boiling point is. A molecule of heavy water that participates in chemical reactions at a slower rate than ordinary water is composed of two heavy hydrogen atoms and one oxygen atom, with a molecular formula of D2O and a relative molecular mass of 20.

Heavy water is an odorless and tasteless liquid that looks very similar to ordinary water, and their chemical properties are the same, but some physical properties are different. The density of ordinary water is 1 gram centimeter, while the density of heavy water is gram centimeter; The boiling point of ordinary water is 100, and the boiling point of heavy water is; The freezing point of ordinary water is 0, and the freezing point of heavy water is. In addition, ordinary water nourishes life and nurtures all things, while heavy water does not make seeds germinate.

A substance that is made up of molecules of the same kind is pure. Both heavy water and superheavy water are composed of two hydrogen atoms and one oxygen atom, both are water molecules, and have exactly the same chemical properties. So, they are the same substance.

It should be noted here that although the number of neutrons in the molecules of heavy water and superheavy water is different, the number of protons is 1, which belongs to the same element, and isotopes are not considered when considering the difference in molecular composition.

The ice starts to melt at 0. It's something everybody knows. However, there is "hot ice" in the world, and it is just melting!

Is it not pure that the water that forms this kind of ice? No, this is authentic water, but it is different from ordinary water, it is called heavy water. Heavy water is water.

An ordinary water molecule is made up of one oxygen atom and two hydrogen atoms. The molecule of heavy water is also composed of one oxygen atom and two hydrogen atoms. The difference between heavy water and ordinary water is that the hydrogen atoms that make up heavy water are not ordinary hydrogen atoms, but heavy hydrogen, whose scientific name is "deuterium".

Heavy hydrogen is also hydrogen: the nucleus of an ordinary hydrogen atom is composed of a proton, while the nucleus of heavy hydrogen contains one more neutron in addition to a proton. 1 litre of heavy water is about a gram heavier than 1 litre of regular water.

In appearance, heavy water is similar to ordinary water, it is a colorless, transparent, flowing liquid. However, they seem to be detached, and their tempers can be very different; If you raise fish in heavy water, it won't take long for the fish to die in their belly, and the rats that drink heavy water will also die quickly; Normally, water boils at 100, and heavy water boils; The solubility of salts in heavy water is less than in ordinary water; Many chemical reactions also proceed more slowly in heavy water than in normal water. And oddly enough:

When solved with an electric current, the molecules of ordinary water are easily "disassembled" by the current into hydrogen and oxygen, running away from the poles. And heavy water will hardly be solved!

And when you think of water, you're all too familiar with it, but there's also a relative molecule of water that's about 11 percent more massive than water, so it's called heavy water, so what's the difference between it and water?

Yes, but the hydrogen atom in it has one neutron and one proton.
