For example,
\[\ce{\underset{(Non-metal)}{C} + O2 -> \underset{(Acidic oxide)}{CO2}}\]
\[\ce{CO2 + H2O -> \underset{Carbonic acid}{H2CO3}}\]

A non-metal A which is the largest constituent of air, when heated with H2 in 1:3 ratio in the presence of catalyst (Fe) gives a gas B. On heating with O2 it gives an oxide C. If this oxide is passed into water in the presence of air it gives an acid D which acts as a strong oxidising agent.
