(2) NO₂
(3) SO₂
(4) P₂O₅
(5) ClO₂

The Attempt at a Solution

I know that,
CO₂ would give carbonic acid only,
NO₂ would probably give nitrous + nitric acid(so this could be the answer?),
SO₂ would give sulphurous acid,
P₂O₅ would give phosphuric(5) acid
for ClO₂,I don't know how it reacts with water.would we get HClO or/& HClO₂ or/& HClO₃ or/& even HClO₄?

Hope someone can help me determine the answer.

Thank you.

You are right about CO₂, SO₂ and P₂O₅, seems like it is a time to check the book or visit library to find details about ClO₂ and NO₂ reactions with water.

Yes,how silly of me,i found the reactions easily on the web
Although ClO2 is highly soluble in water,it doesn't hydrolise in water,
and NO2 upon hydrolysis,would give NO + HNO3

Thank you
