- AWater at ${4^o}C$
- ✓Compound of deuterium and oxygen
- CCompound of heavy oxygen and heavy hydrogen
- DWater, in which soap does not lather
✓
Answer
Correct option: B.
Compound of deuterium and oxygen
b
Heavy water is water that contains heavy hydrogen or deuterium. Deuterium differs from the hydrogen usually found in water, protium, in that each atom of deuterium contains a proton and a neutron. Heavy water may be deuterium oxide, $D _2 O$ or it may be deuterium protium oxide,$DHO$. Heavy water occurs naturally, although it is much less common than regular water.
