Which of the following is the chemical formula of water vapour?
Answer and explanation
Correct answer: H₂O
H₂O is the chemical formula for water, consisting of two hydrogen atoms bonded to one oxygen atom. When water exists in the gaseous state, it is called water vapour. Water vapour is naturally present in the atmosphere and is also an important greenhouse gas because it absorbs and re-emits infrared radiation. CO₂ is carbon dioxide, O₃ is ozone, and N₂ is nitrogen, so H₂O is the only correct answer.
