FeO + 2HCl ->FeCl2+ H2O
nHCl=0,3.2=0,6(mol)
Theo PTHH ta cso:
\(\dfrac{1}{2}\)nHCl=nFeO=nFeCl2=0,3(mol)
mFeO=72.0,3=21,6(g)
CM dd FeCl2=\(\dfrac{0,3}{0,3}=1M\)
a, PT: FeO+2HCl---->FeCl2+H2O
b, nHCl=2.0,3=0,6 mol
Theo pt: nFeO=\(\dfrac{1}{2}.n_{HCl}\)= \(\dfrac{1}{2}.0,6=0,3\) mol
=> mFeO= 0,3.72= 21,6 g
c, theo pt: nFeCl2=\(\dfrac{1}{2}.n_{HCl}=\dfrac{1}{2}.0,6=0,3\)mol
=> CM dd FeCl2=\(\dfrac{0,3}{0,3}=1\) M
