Question

how to understand the reaction mechanism of heavy water used as a tracer​

Answer 1

Answer:

Heavy water (deuterium oxide, 2

H

2O, D

2O) is a form of water that contains only deuterium (2

H or D, also known as heavy hydrogen) rather than the common hydrogen-1 isotope (1

H or H, also called protium) that makes up most of the hydrogen in normal water.[4] The presence of the heavier hydrogen isotope gives the water different nuclear properties, and the increase of mass gives it slightly different physical and chemical properties when compared to normal water.

Answer 2

Answer:

Cells are the basic building blocks of all living things. ... Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
