H2+Cl2->2HCl
0,35---0,7 mol
n H2=\(\dfrac{8,96}{22,4}\)=0,4 mol
n Cl2=\(\dfrac{7,84}{22,4}\)=0,35 mol
=>H2 dư :0,05 mol
=>VHCl=0,7.22,4=15,68l
b) C% HCl=\(\dfrac{0,7.36,5}{25,55+224,45}\).100=10,22%
a: \(H_2+Cl_2\rightarrow2HCl\)
\(n_{H_2}=\dfrac{8.96}{22.4}=0.4\left(mol\right)\)
\(n_{Cl_2}=\dfrac{7.84}{22.4}=0.35\left(mol\right)\)
=>Cl2 thiếu, H2 dư
\(V_{HCl}=2\cdot V_{Cl_2}=0.7\left(mol\right)\)
