mik xin sửa chỗ hệ pt :
\(\left\{{}\begin{matrix}28x+16y=1,7\\x+y=0,08\end{matrix}\right.=>\left\{{}\begin{matrix}x=0,035\left(mol\right)\\y=0,045\left(mol\right)\end{matrix}\right.\)
=> %VCO=43,75(%)
%VCH4=56,25(%)
2CO + O2 -to-> 2CO2 (1)
CH4 +2O2 -to-> CO2 +2H2O (2)
CO2 +Ca(OH)2 --> CaCO3 +H2O (3)
nCaCO3=0,08(mol)
=>nCO2=0,08(mol)
giả sử nCO=x(mol)
nCH4=y(mol)
=> \(\left\{{}\begin{matrix}28x+16y=1,7\\x+2y=0,08\end{matrix}\right.=>\left\{{}\begin{matrix}x=0,053\left(mol\right)\\y=0,0135\left(mol\right)\end{matrix}\right.\)
=>%VCO=79,7(%)
=>%Vch4=20,3(%)
