The equation for the complete combustion of gaseous methylamine is:
4CH3NH2(g)+9O2(g)→4CO2(g)+10H2O(g)+2N2(g) 4\text{CH}_3\text{NH}_2(\text{g}) + 9\text{O}_2(\text{g}) \rightarrow 4\text{CO}_2(\text{g}) + 10\text{H}_2\text{O}(\text{g}) + 2\text{N}_2(\text{g}) 4CH3NH2(g)+9O2(g)→4CO2(g)+10H2O(g)+2N2(g)What is the mole fraction of methylamine in a gaseous reactant mixture containing the minimum quantity of oxygen required for complete combustion?
