Miscellaneous Reactions of oxygen

Reaction with Alkanes: The most common reactions that involve alkanes occur with oxygen. Alkanes are able to burn and it is the process of oxidizing the hydrocarbons that makes them important as fuels. An example of an alkane reaction is the reaction of octane with oxygen as showed below.

C₈H₁₈(l) + 25/2 O₂(g) → 8CO₂(g) + 9H₂O(l)  ∆H_o = -5.48 X 10³ kJ

Reaction with ammonia: Oxygen is able to react with ammonia to produce dinitrogen (N₂) and water (H₂O) through the reaction shown below.

Reaction with Nitrogen Oxide: Oxygen is able to react with nitrogen oxide in order to produce nitrogen dioxide through the reaction shown below.
