a, Ta co pthh
3H2+ Fe2O3\(\rightarrow\)2Fe + 3H2O
b, Theo de bai ta co
n Fe=\(\dfrac{22,4}{56}=0,4mol\)
theo pthh
nH2=3nFe=3*0,4=0,12 mol
\(\Rightarrow\)VH2=0,12*22,4=2,68 l
c, Theo pthh
nFe2O3=\(\dfrac{1}{2}nFe=\dfrac{1}{2}.0,4=0,2mol\)
\(\Rightarrow\)mFe2O3=0,2*160=32 g
a) PTHH: Fe2O3 + 3H2 -to-> 2Fe + 3H2O
b) \(n_{Fe}=\dfrac{22,4}{56}=0,4\left(mol\right)\)
=> \(n_{H_2}=\dfrac{3.0,4}{2}=0,6\left(mol\right)\\ n_{Fe_2O_3}=\dfrac{0,4}{2}=0,2\left(mol\right)\)
b) \(V_{H_2\left(đktc\right)}=0,6.22,4=13,44\left(l\right)\)
c) \(m_{Fe_2O_3}=0,2.160=32\left(g\right)\)
