3CO + Fe2O3 → 2Fe + 3CO2 (1)
a) \(n_{CO}=\dfrac{13,44}{22,4}=0,6\left(mol\right)\)
theo PT1: \(n_{Fe_2O_3}=\dfrac{1}{3}n_{CO}=\dfrac{1}{3}\times0,6=0,2\left(mol\right)\)
\(\Rightarrow m_{Fe_2O_3}=0,2\times160=32\left(g\right)\)
b) Theo PT1: \(n_{Fe}=\dfrac{2}{3}n_{CO}=\dfrac{2}{3}\times0,6=0,4\left(mol\right)\)
\(\Rightarrow m_{Fe}=0,4\times56=22,4\left(g\right)\)
c) 2HCl + Fe → FeCl2 + H2 (2)
Theo PT2: \(n_{H_2}=n_{Fe}=0,4\left(mol\right)\)
\(\Rightarrow V_{H_2}=0,4\times22,4=8,96\left(l\right)\)
Theo PT2: \(n_{HCl}=2n_{Fe}=2\times0,4=0,8\left(mol\right)\)
\(\Rightarrow m_{HCl}=0,8\times36,5=29,2\left(g\right)\)
\(\Rightarrow m_{ddHCl}=\dfrac{29,2}{14,6\%}=200\left(g\right)\)
nCO = \(\dfrac{13,44}{22,4}\)= 0,6 mol
3CO + Fe2O3 ->2Fe + 3CO2
0,6-->0,2------>0,3
a) mFe2O3 = 0,2. 160 = 32 g
b)mFe = 0,3 . 56 = 16,8 g
c)
Fe +2 HCl -> FeCl2 + H2
0,3->0,6--------------->0,3
VH2 = 0,3.22,4 = 6,72 (l)
=>mHCl(d2) = \(\dfrac{0,6.36,5.100}{14,6}\)= 150 g
