Answer:
SO₃(g) + H₂O(l) → H₂SO₄(aq)
Step-by-step explanation:
The molecular formula for the involved species are:
- Sulfur trioxide = SO₃. ("trioxide" indicates the presence of 3 oxygen atoms).
With the above information in mind we can proceed to write the reaction equation:
- SO₃(g) + H₂O(l) → H₂SO₄(aq)
