CxHyOz +(4x+y) O2 \(\underrightarrow{t^0}\) 4x CO2 + 2y H2O
Khi dot 1 mol gluxit se tao ra 1 mol CO2 va 0,5 mol H2O hay cu 1 mol gluxit bi dot chay se tao ra 44x gam CO2 va 9y gam H2O
Theo de bai \(\dfrac{9y}{44x}=\dfrac{33}{88}\)
\(\Rightarrow\dfrac{y}{x}=\dfrac{44.33}{9.88}=\dfrac{11}{6}=\dfrac{22}{12}\)
CnH2mOm + nO2 \(\underrightarrow{t^0}\) nCO2 +mH2O
\(\Rightarrow\dfrac{m}{n}=\dfrac{44.33}{9.88}=\dfrac{11}{6}\)
