\(n_{H_2}=\dfrac{6.72}{22.4}=0.3\left(mol\right)\)
\(n_{Cl_2}=\dfrac{1.12}{22.4}=0.05\left(mol\right)\)
\(H_2+Cl_2\underrightarrow{^{^{as}}}2HCl\)
\(n_{H_2}>n_{Cl_2}\Rightarrow H_2dư\)
\(m_{HCl}=0.05\cdot2\cdot36.5=3.65\left(g\right)\)
$n_{H_2} = 0,3(mol) ; n_{Cl_2} = 0,05(mol)$
$H_2 + Cl_2 \xrightarrow{ánh\ sáng} 2HCl$
Ta thấy : $n_{H_2} > n_{Cl_2}$ nên Hidro dư
$n_{HCl} = 2n_{Cl_2} = 0,1(mol)$
$m_{HCl} = 0,1.36,5 = 3,65(gam)$
nCl2=1.1222.4=0.05(mol)nCl2=1.1222.4=0.05(mol)
