Gọi a, b lần lượt là số mol CH4, O2
Ta có \(\left\{{}\begin{matrix}a+b=\dfrac{5,6}{22,4}\\16a+32b=5,6\end{matrix}\right.\)
=> \(\left\{{}\begin{matrix}a=0,15\\b=0,1\end{matrix}\right.\)
CH4 + 2O2 → CO2 + 2H2O
0,15.....0,1.......
Lập tỉ lệ : \(\dfrac{0,15}{1}>\dfrac{0,1}{2}\) => CH4 dư, O2 hết
\(n_{CH_4\left(dư\right)}=0,15-\dfrac{0,1}{2}=0,05\left(mol\right)\)
=> \(V_{CH_4}=0,1.22,4=2,24\left(l\right)\)
\(m_{CO_2}=\dfrac{0,1}{2}.44=2,2\left(g\right)\)
\(m_{H_2O}=0,1.18=1,8\left(g\right)\)
