1) PTHH: 2Fe2O3 + 3CO →4Fe + 3CO2
2) nco=\(\dfrac{V}{22,4}\)=\(\dfrac{3,36}{22,4}=0,15\)(mol)
-Theo PTHH, ta có:
2.nFe2O3=3.nCO=4.nFe=3.nCO2=3.0,15=0,45(mol)
=>nFe2O3=\(\dfrac{0,45}{2}=0,225\left(mol\right)\)
=>mFe2O3=n.M=0,225.(56.2+16.3)=36(g)
c)- Ta có: 3.nCO2=3.0,15=0,45(mol)
=>nCO2=\(\dfrac{0,45}{3}=0,15\left(mol\right)\)
=>VCO2=n.22,4=0,15.22,4=3,36(lít)
