Ответы на вопрос




Why is deuterium oxide called heavy water?
Deuterium oxide, also known as heavy water, is called "heavy" because it contains a larger amount of the isotope deuterium compared to regular water, which consists mostly of the lighter isotope of hydrogen, protium. The presence of deuterium in heavy water makes it heavier than regular water.
The chemical formula for heavy water is D2O, where the "D" represents deuterium, an isotope of hydrogen with one proton and one neutron in its nucleus, making it twice as heavy as the more common protium isotope of hydrogen.
Heavy water has a higher boiling point and freezing point compared to regular water, and it is also denser. These physical differences are due to the increased mass of deuterium in heavy water, which affects its properties and behavior compared to regular water.
In addition to its use as a moderator in nuclear reactors, heavy water also has various industrial and scientific applications due to its unique properties
