Question

C) 99 %
(d) 100%
Deuterium is used to make:
(a) Light water
(b) Heavy water
(c) Soft water
(d) Hard water​

Answer 1

Answer: Hey! Option D is the correct one. Hope this helps you-

Heavy water (D2O), also called deuterium oxide, water composed of deuterium, the hydrogen isotope with a mass double that of ordinary hydrogen, and oxygen. (Ordinary water has a composition represented by H2O.) Thus, heavy water has a molecular weight of about 20 (the sum of twice the atomic weight of deuterium, which is 2, plus the atomic weight of oxygen, which is 16), whereas ordinary water has a molecular weight of about 18 (twice the atomic weight of ordinary hydrogen, which is 1, plus oxygen, which is 16).

Explanation:

Answer 2

Deuterium is used to make heavy water.
