Answer:

It is chemically transformed to give #CO_2# or some other oxide......

Explanation:

And were we to burn methane, i.e. natural gas.....

#CH_4(g) + 2O_2(g) rarr CO_2(g) + 2H_2O(l) + Delta#

The dioxygen molecule, #stackrel(0)O_2#, is REDUCED to give #stackrel(-II)O#; and carbon has been oxidized from #stackrel(-IV)C#, is OXIDIZED to give #stackrel(+IV)C#.
