Chúc bạn học tốt
số mol C2H4 là:
\(n_{C_2H_4}=\frac{5,6}{22,4}=0,25\left(mol\right)\)
a)C2H4 + 3O2→2CO2+2H2O
từ pthh :\(V_{CO_2}=n_{CO_2}.22,4=\left(0,25.2\right).22,4=11,2\left(l\right)\)
\(m_{H_2O}=n_{H_2O}.M_{H_2O}=\left(0,25.2\right).\left(1.2+16\right)=9\left(g\right)\)
a) C2H4+3O2----to--->2CO2+2H2O
b) n C2H4=5,6/22,4=0,25(mol)
Theo pt n CO2=2n C2H4=0,5(mol)
=>V CO2(đktc)= 0,5.22,4=11,2(l)
c) Theo pt n H2O=2n C2H4=0,5(mol)
m H2O=18.0,5=9(g)
