\(n_{hh}=\dfrac{11,2}{22,4}=0,5\left(mol\right)\)
\(n_{O2}=\dfrac{9,408}{22,4}=0,42\left(mol\right)\)
\(O2+2H2\rightarrow2H2O\)
\(O2+2CO\rightarrow2CO2\)
Theo PT
\(n_{O2}=\dfrac{1}{2}n_{hh}=0,25\left(mol\right)\)
=>O2 dư
b) Gọi \(\left\{{}\begin{matrix}n_{H2}=3x\\n_{CO}=2x\end{matrix}\right.\)
\(\Rightarrow3x+2x=0,5\)
\(\Rightarrow x=0,1\)
\(n_{CO2}=n_{CO}=0,2\left(mol\right)\)
\(\Rightarrow V_{CO2}=0,2.22,4=4,48\left(l\right)\)
\(n_{H2O}=n_{H2}=0,3\left(mol\right)\)
\(\Rightarrow m_{H2O}=0,3.18=5,4\left(g\right)\)
Chúc bạn học tốt ^^
