\(CH_4+2O_2\rightarrow CO_2+2H_2O\)
a, Theo phản ứng :
\(V_{O2}=V_{CH4}=4,48.2=8,96\left(l\right)\)
\(\Rightarrow V_{kk}=\frac{1}{5}.V_{O2}=\frac{1}{5}.8,96=1,782\left(l\right)\)
nCH4= 4,8/16=0,3(mol)
PTHH: CH4+ 2 O2 -to-> CO2 + 2 H2O
0,3___________0,6______0,3(mol)
V(O2,đktc)=0,6.22,4=13,44(l)
Vì : V(O2,đktc)=1/5.Vkk
=>Vkk=5.V(O2,đktc)=5.13,44=67,2(l)
\(n_{CH_4}=\frac{4,8}{16}=0,3\left(mol\right)\)
\(PTHH:CH_4+2O_2\underrightarrow{t^o}CO_2+2H_2O\)
(mol)_____0,3____0,6_______________
\(V_{KK}=5.V_{O_2}=5.\left(22,4.0,6\right)=67,2\left(l\right)\)
