PTHH: 2Fe + 3Cl2--> 2FeCl3
Ta có: nFe=5,6/56=0,1 mol
Theo PTHH ta có:
nFeCl3 = nFe , nCl2=3nFe/2=0,15 mol
=> VCl2=0,15.22,4=3,36 l
mFeCl3=162,5.0,1=16,25 g
\(n_{Fe}=\dfrac{5.6}{56}=0.1\left(mol\right)\)
\(Fe+\dfrac{3}{2}Cl_2\underrightarrow{^{^{t^0}}}FeCl_3\)
\(0.1......0.15........0.1\)
\(V_{Cl_2}=0.15\cdot22.4=3.36\left(l\right)\)
\(m_{FeCl_3}=0.1\cdot162.5=16.25\left(g\right)\)
