a) PTHH :
\(\left(1\right)2CO+O2-^{t0}->2CO2\)
\(\left(2\right)2H2+O2-^{t0}->2H2O\)
b) \(Theo-\text{đ}\text{ề}-b\text{à}-ta-c\text{ó}:nCO2=\dfrac{8,8}{44}=0,2\left(mol\right)\)
Theo PTHH 1 ta có :
\(nO2=\dfrac{1}{2}nCO2=0,1\left(mol\right)\)
nCO = nCo2 = 0,2 (mol)
=> nO2(2) = \(\dfrac{9,6-0,1.32}{32}=0,2\left(mol\right)\)
Theo PTHH 2 ta có :
nH2 = 2nO2=2.0,2=0,4(mol)
=> \(\left\{{}\begin{matrix}\%mCO=\dfrac{0,2.28}{0,2.28+0,4.2}.100\%=87,5\%\\\%mH2=100\%-87,5\%=12,5\%\end{matrix}\right.\)
