\(PTHH:Fe+2HCl->FeCl_2+H_2\)
0,15<--0,3<------0,15<-----0,15 (mol)
\(n_{H_2\left(dktc\right)}=\dfrac{V}{22,4}=\dfrac{3,36}{22,4}=0,15\left(mol\right)\)
\(m_{Fe}=n\cdot M=0,15\cdot56=8,4\left(g\right)\)
\(m_{FeCl_2}=n\cdot M=0,15\cdot\left(56+71\right)=19,05\left(g\right)\)
PTPU: Fe + 2HCl ----> FeCl2 + H2
nH2= V / 22,4 = 3,36 / 22,4 = 0,15 mol
nFe = nH2 = 0,15 mol
=> mFe = n . M = 0,15 . 56 = 8,4g
nHCl = 2nH2 = 0,3 mol
=> nHCl = n . M = 0,3 . 36,5 = 10,95g
