Solution

1) Carbon dioxide dissolves in water to form carbonic acid .
CO₂ + H₂O → H₂CO₃
2) Calcium oxide reacts with water to calcium hydroxide.
3) Sulphur dioxide will react with water to form sulphurous acid.
4) Nitrogen dioxide will react with water to form nitric acid.
Hence , calcium oxide will not react with water to form acid.
