Generally, the non-metals do not react with dilute acids. This is because when a substance reacts with acids, it provides electrons to the H+ ions produced by the acids. Non-metals are themselves acceptors of electrons so there is no way they can donate electrons to the hydrogen ion of the acid. Hence, non-metals in general do not react with dilute acids.
However, some none metals are the exceptions which react with acid and oxidized to their corresponding oxide. Like, P,S, carbon etc.
For ex: 6HNO3+ S - H2SO4+ 6NO2+ 2H2O
Non-metals will normally not react with water, however, non-metal oxides will react with water to form acids. In this example,chlorine gaswill react with water to formhydrochloric acidandhypochlorous acid.
