Methane, CH4, burns in oxygen gas to form water and carbon dioxide. What is the correct balanced chemical equation for this reaction?

I'm having a hard time understanding how to balance a chemical equation. I'm really not sure how to even begin. Please help!

Respuesta :

This is a combustion reaction. For complete combustion reaction the equation will be the:
          CH4 + 2O2 =====> CO2  +  2 H2O

And for incomplete combustion, 
          3CH4 + 4O2 ======>  C + 2CO + 6H2O
