The Correct answer is B
The term “Heavy water” refers to deuterium oxide (D2O), which is a substance composed of the chemical elements hydrogen and oxygen. Heavy water is sometimes referred to as “Dihydrogen oxide”, “water vapor”, “distilled water”, “ice”, “H2O”, or “steam”.
Heavy water is produced through processes such as fractional distillation, chemical exchange, and electrolysis. Heavy water has been studied for its biological effects, such as its ability to induce the exchange of deuterium between deuterium oxide and molecular hydrogen. This reaction was studied by irradiating heavy water with gamma rays from Co. Thus, the term “Heavy water” refers to deuterium oxide.
The correct answer is B) Deuterium oxide
The term “Heavy water” refers to B) Deuterium oxide (D2O).
Deuterium oxide, also known as heavy water, is a form of water that contains a larger isotope of hydrogen called deuterium.
Deuterium atoms have an extra neutron in their nucleus, which makes them heavier than regular hydrogen atoms. Heavy water is chemically identical to regular water, but it has different nuclear properties, which makes it useful in certain applications such as nuclear reactors and in certain medical treatments.
Additional Information Option Wise
Option A) Ice refers to water that is frozen and solid, but it is not heavy water.
Option C) Redistilled water refers to water that has been purified by distillation and then distilled again, but it is not heavy water.
Option D) Water is a general term that can refer to any type of water, including heavy water.
