a)\(CH4+2O2-->CO2+2H2O\)
b)\(n_{CH4}=\frac{11,2}{22,4}=0,5\left(mol\right)\)
\(n_{CO2}=n_{CH4}=0,5\left(mol\right)\)
\(V_{CO2}=0,5.44=22\left(g\right)\)
c)\(n_{O2}=2n_{CH4}=1\left(mol\right)\)
\(V_{O2\left(đktc\right)}=1.22,4=22,4\left(l\right)\)
a. \(CH_4+2O_2\rightarrow2H_2O+CO_2\)
b+c. \(n_{CH_4}=\frac{11,2}{22,4}=0,5\left(mol\right)\)
Theo PTHH: \(n_{CO_2}=n_{CH_4}=0,5\left(mol\right)\Rightarrow m_{CO_2}=0,5.44=22\left(g\right)\)
\(n_{O_2}=2n_{CH_4}=2.0,5=1\left(mol\right)\Rightarrow V_{O_2}=1.22,4=22,4\left(l\right)\)
