First of all, we have to start with a balanced reaction. Let’s say that we have this equation, which is the combustion of methane. CH_4 + O_2 \rightarrow CO_2 + H_2O C H 4 +O2 → C O2 +H 2O. Now, this equation is not yet balanced.The mixture of the hydrocarbon and oxygen is sparked so that a complete combustion reaction occurs, producing CO2(g) and H2O(g). The partial pressures of these gases at 127°C are 0.600 atm for CO2(g) and 0.800 atm for H2O(g). There is O2(g) remaining in the container after the reaction is complete.
