during the combustion of methane (CH4), one mole of methane gas combines with two moles of oxygen gas (O2) to produce one mole of carbon dioxide gas (CO2) and two moles of water vapor. Which of the fallowings chemical equations correctly represents the combustion of methane described above?

Respuesta :

  The equation that  correctly  represents  the  combustion of methane  decribe  above

CH4(g) + 2O2(g) = Co2(g) + H2O(g)

 1 mole  of CH4   react with    2 moles  to form 1 mole Co2  and 1 mole  H2O
