WebFor stoichiometric methane combustion with air, the balanced reaction equation reads: CH 4þ 2ðO 2þ3:76N 2Þ!1CO 2þ 2H 2Oþ 7:52N 2: (2.11) Note that on the reactant side there are 2·(1+3.76) or 9.52 mol of air and its molecular mass is 28.96 kg/kmol. In this text, the reactions are balanced using 1 mol of fuel. WebStoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers. This means that if the amounts of the separate reactants are known, then the amount of the …
