\(n_{Fe}=\dfrac{33.6}{56}=0.6\left(mol\right)\)
\(Fe_2O_3+3H_2\underrightarrow{^{^{t^0}}}2Fe+3H_2O\)
\(0.3..........0.9......0.6\)
\(m_{Fe_2O_3}=0.3\cdot160=48\left(g\right)\)
\(V_{H_2}=0.9\cdot22.4=20.16\left(l\right)\)
a) n Fe = 33,6/56 = 0,6(mol)
Fe2O3 + 3H2 \(\underrightarrow{t^o}\) 2Fe + 3H2O
Theo PTHH :
n Fe2O3 = 1/2 n Fe = 0,3(mol)
m Fe2O3 = 0,3.160 = 48(gam)
c) n H2 = 3/2 n Fe = 0,9(mol)
V H2 = 0,9.22,4 = 20,16(lít)
