a) \(n_{CH_4}=\dfrac{v}{22,4}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\)
\(CH_{4_{ }}+2O_2\underrightarrow{t^o}CO_2+2H_2O\)
1mol 2mol 1mol 2mol
0,2mol 0,4mol 0,2mol 0,4mol
b) \(v_{CO_2}=n.22,4=0,2.22,4=4,48\left(l\right)\)
a) CH4 + 2O2 \(\underrightarrow{to}\) CO2 + 2H2O
b) \(n_{CH_4}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\)
Theo PT: \(n_{CO_2}=n_{CH_4}=0,2\left(mol\right)\)
\(\Rightarrow V_{CO_2}=0,2\times22,4=4,48\left(l\right)\)
c) Theo PT: \(n_{O_2}=2n_{CH_4}=2\times0,2=0,4\left(mol\right)\)
\(\Rightarrow V_{O_2}=0,4\times22,4=8,96\left(l\right)\)
\(V_{KK}=5V_{O_2}=5\times8,96=44,8\left(l\right)\)
a) nCH4=\(\dfrac{v}{22,4}\)=\(\dfrac{4,48}{22,4}\)=0,2(mol)
CH4+2O2→CO2+2H2O
b) nCH4=\(\dfrac{4,48}{22,4}\)=0,2(mol)
Theo PT: nCO2=nCH4=0,2(mol)nCO2=nCH4=0,2(mol)
⇒VCO2=0,2×22,4=4,48(l)
c) Theo PT: nO2=2nCH4=2×0,2=0,4(mol)
⇒VO2=0,4×22,4=8,96(l)
VKK=5VO2=5×8,96=44,8(l)
