Se quema etano (C₂H₆) con oxigeno produciendo dioxido de carbono (CO₂) y agua como vapor, si se hace arder 1,9 Kg de etano C₂H₆ + 2O₂---------> CO₂ + 2H₂O Determina A)Los gramos de oxigeno que se necesitan para que ocurra la combustión B)Cuantos gramos de dioxido de carbono se produjeron

Te anexo el procedimiento en las siguientes fotos. Saludos.
Incluso el balanceo.
