Dear Student, Please find below the balanced chemical equation:

D2O: It is called heavy water It is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium Applications of D2O: Deuterium oxide is used in nuclear magnetic resonance spectroscopy when the solvent of interest is water and the nuclide of interest is hydrogen Deuterium oxide is often used as the source of deuterium for preparing specifically labelled isotopologs of organic compounds For example, C-H bonds adjacent to ketonic carbonyl groups can be replaced by C-D bonds, using acid or base catalysis Deuterium oxide is often used instead of water when collecting spectra of proteins in solution Heavy water is used in certain types of nuclear reactors where it acts as a neutron moderator to slow down neutrons Heavy water is employed as part of a mixture with H218O for a common and safe test of mean metabolic rate in humans and animals undergoing their normal activities Heavy water is also used in the production of tritium Hope this information clears your doubts about the topic Keep asking!! Regards
