PTHH; CH4 + 2O2 → 2H2O + CO2↑
nCH4=3,2\16=0,2(mol)
Theo PTHH, ta có: nO2=2nCH4=2.0,2=0,4(mol))
⇒VO2=0,4.22,4=8,96(l)
Theo PTHH, ta có:nCO2=nCH4=0,2(mol)
⇒mCO2=0,2.48=9,6(g)
\(n_{CH_4}=\dfrac{3.2}{16}=0.2\left(mol\right)\)
\(CH_4+2O_2\underrightarrow{t^0}CO_2+2H_2O\)
\(0.2........0.4........0.2\)
\(V_{O_2}=0.4\cdot22.4=8.96\left(l\right)\)
\(m_{CO_2}=0.2\cdot44=8.8\left(g\right)\)
