Non-metals react with oxygen to produce non-metallic oxides, which are compounds of oxygen and non-metals. Non-metallic oxides are covalent compounds, meaning that they are formed by the sharing of electrons between atoms.

These compounds are typically acidic in nature and react with water to form acids. Some common examples of non-metallic oxides include carbon dioxide (CO2), sulfur dioxide (SO2), and nitrogen dioxide (NO2).

Here are the reactions of some non-metals with oxygen:

- Carbon reacts with oxygen to produce carbon dioxide (CO2).

2C(s) + O2(g) → 2CO2(g)

- Hydrogen reacts with oxygen to produce water (H2O).

2H2(g) + O2(g) → 2H2O(g)

- Nitrogen reacts with oxygen to produce nitrogen dioxide (NO2).

N2(g) + 2O2(g) → 2NO2(g)

- Phosphorus reacts with oxygen to produce phosphorus pentoxide (P2O5).

4P(s) + 5O2(g) → 2P2O5(s)

- Sulfur reacts with oxygen to produce sulfur dioxide (SO2).

S(s) + O2(g) → SO2(g)
