Gaseous methane (CH4) reacts with gaseous oxygen gas (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2o) . What is the theoretical yield of carbon dioxide formed from the reaction of 0.16g of methane and 0.83g of oxygen gas?

CH4+2O2>> CO2 + 2H2O
so for each mole of methane, you get one mole of carbon dioxide.
So we have to see the limiting agents.
You are given .16/16 moles .01 moles of methane. You must have twice that of oxygen see the ratio moles O2=.83/32 which is greater than .02, so the limiting reagent is methane. Then you ought to get .01 moles carbon dioxide, ord .44 grams.
