\(n_{Fe_2O_3}=\dfrac{32}{160}=0.2\left(mol\right)\)
\(Fe_2O_3+3H_2\underrightarrow{^{^{t^o}}}2Fe+3H_2O\)
\(0.2........0.6........0.4........0.6\)
\(V_{H_2}=0.6\cdot22.4=13.44\left(l\right)\)
\(m_{Fe}=0.4\cdot56=22.4\left(g\right)\)
Số phân tử H2O là : \(0.6\cdot6\cdot10^{23}=3.6\cdot10^{23}\left(pt\right)\)
a, \(n_{Fe_2O_3}=\dfrac{32}{160}=0,2\left(mol\right)\)
PTHH: 3H2 + Fe2O3 ---to→ 2Fe + 3H2O
Mol: 0,6 0,2 0,4 0,6
b, \(V_{H_2}=0,6.22,4=13,44\left(l\right)\)
c, \(m_{Fe}=0,4.56=22,4\left(g\right)\)
d, \(N=0,6.6.10^{23}=3,6.10^{23}\) (phân tử)
