a,
\(2CO+H_2\rightarrow2CO_2\)
0,2___0,1____0,2
\(2H_2+O_2\rightarrow2H_2O\)
0,4 ___0,2_______
b,Ta có
\(\left\{{}\begin{matrix}n_{O2}=\frac{9,6}{32}=0,3\left(mol\right)\\n_{CO2}=\frac{8,8}{44}=0,2\left(mol\right)\end{matrix}\right.\)
\(\Rightarrow\left\{{}\begin{matrix}\%m_{CO}=\frac{0,2.28}{0,2.28+0,4.2}=87,5\%\\\%m_{H2}=100\%-87,5\%=12,5\%\end{matrix}\right.\)
