The balanced equation for the reduction of iron ore to
the metal using CO is
Fe2O3 (s) + 3CO (g) ----> 2Fe (s) + 3CO2 (g)
1)
Molar mass of Fe2O3,
MM = 2*MM(Fe) + 3*MM(O)
= 2*55.85 + 3*16.0
= 159.7 g/mol
mass of Fe2O3 = 9.37*10^2 g
mol of Fe2O3 = (mass)/(molar mass)
= 9.37*10^2/1.597*10^2
= 5.867 mol
Balanced chemical equation is:
Fe2O3 (s) + 3CO (g) ----> 2Fe (s) + 3CO2 (g)
According to balanced equation
mol of Fe formed = (2/1)* moles of Fe2O3
= (2/1)*5.867
= 11.73 mol
Molar mass of Fe = 55.85 g/mol
mass of Fe = number of mol * molar mass
= 11.73*55.85
= 655 g
Answer: 655 g
2)
According to balanced equation
mol of CO required = (3/1)* moles of Fe2O3
= (3/1)*5.867
= 17.6 mol
Molar mass of CO,
MM = 1*MM(C) + 1*MM(O)
= 1*12.01 + 1*16.0
= 28.01 g/mol
mass of CO = number of mol * molar mass
= 17.6*28.01
= 493 g
Answer: 493 g

Blast furnaces extract pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C (s) + O2 (g) → 2CO (g) In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe2O3 (s) + 3CO (g) → 2Fe (s) + 3CO2 (g) Write the net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide....
