\(n_{FeO}=\dfrac{14.4}{72}=0.2\left(mol\right)\)
\(FeO+H_2\underrightarrow{^{t^0}}Fe+H_2O\)
\(0.2.....0.2......0.2\)
\(V_{H_2}=0.2\cdot22.4=4.48\left(l\right)\)
\(m_{Fe}=0.2\cdot56=11.2\left(g\right)\)
nFeO=0,2(mol)
a) PTHH: FeO + H2 -to-> Fe + H2O
0,2___________0,2______0,2(mol)
V(H2,đktc)=0,2.22,4=4,48(l)
b) mFe=0,2.56=11,2(g)
