Uses of Oxygen. Most widely used as an oxidizing agent. (E.g. in the steel industry to remove impurities.) Oxygen is used in medicine. It is used with acetylene, C2H2 for oxyacetylene welding:
In $\ce{CH4}$, carbon has 8 electrons due to 4 covalent bonds. In $\ce{CO2}$, carbon has 8 electrons due to 2 double bonds. In both cases, carbon has 8 electrons. So why is carbon oxidised?
