1 Answer

Answer :

(4) Deuterium oxide Explanation: Heavy water is deuterium oxide (2H2O). It is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium (2H or D, also known as heavy hydrogen), rather than the common hydrogen-1 isotope (1H or H, also called protium) that makes up most of the hydrogen in normal water.
