As with any combustion reaction, the products of combusting a hydrocarbon fuel (cxhy) with oxygen (o2) are carbon dioxide (co2) and water (h2o).
a mass of 16.74 g for an unknown fuel was combusted in a reaction vessel containing an unknown amount of oxygen. at the end of the reaction, there still remained 16.70 g of the fuel as well as 0.0654 g of water and 0.1198 g of carbon dioxide. the oxygen was completely consumed during the reaction.
how many molecules of oxygen gas were initially present in the reaction vessel?
me, i will be very . the topic is limiting reagents and theoretical yields.
