Question

what is d2o? tell me please it's practical information.
​

Answer 1

Explanation:

Deuterium Oxide is a stable, non-radioactive isotopic form of water, containing 2 atoms of deuterium (D) and one atom of oxygen (2D2O), with DNA-labeling activity. Upon ingestion of deuterium oxide, 2H is incorporated into the deoxyribose moiety of DNA of newly divided cells. Rapidly dividing cells, as in the case of B-cell chronic lymphocytic leukemia (B-CLL), can be labeled with deuterium oxide and measured using gas chromatography and/or mass spectrometry.

Answer 2

hey mate here is your answer:-

Heavy water is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium, rather than the common hydrogen-1 isotope that makes up most of the hydrogen in normal water.

IUPAC ID: [2H]2-water

Boiling point: 101.4 °C
