In ironmaking, iron metal can be separated from iron ore (Fe2O3) by heating the ore in a blast furnace in the presence of coke,
mel-nik [20]

The limiting reactant is iron ore, the theoretical yield of iron metal is 701.344 kg, and the theoretical yield of carbon dioxide is 413.292 kg.

<h3>Stoichiometric problem</h3>

From the equation of the reaction:

2 Fe_2O_3(s) + 3 C(s) --- > 4 Fe(s) + 3 CO_2(g)

The mole ratio of iron ore to carbon is 2:3.

Mole of 1000 kg of iron ore = 1000000/159.69

                                          = 6,262 moles

Mole of 120 kg carbon = 120000/12

                                 = 10,000 moles

Thus, it appears that the carbon is in excess while the iron ore is limited in availability.

The mole ratio of the iron ore and the iron produced is 1:2. Thus, the equivalent number of moles of iron produced will be:

              6,262 x 2 = 12,524 moles

Mass of 12,524 moles of iron = 12,524 x 56

                                                = 701,344 g or 701.344 kg

Thus, the theoretical yield of iron is 701.344 kg.

The mole ratio of the iron ore and the carbon dioxide produced is 2:3. The equivalent mole of carbon dioxide produced will be:

         6,262 x 3/2 = 9,393 moles

Mass of 9,393 moles carbon dioxide = 9,393 x 44

                                                         = 413,292 or 413.292 kg

The theoretical yield of carbon dioxide is, therefore, 413.292 kg.

The following balanced equation shows the formation of ammonia. N2 + 3H2 mc0
Tcecarenko [31]
                                     N₂   +   3H₂    →    2NH₃

Based on the reaction, Mole ratio of H₂  to  N₂   is   3  :  1  [ 1N₂ + 3H₂  → 2NH₃]

∴ if moles of Hydrogen = 6.34 mol 
then moles of nitogen = 6.34 mol ÷ 3
                                    = 2.11 moles

∴ 2.11 moles (OPTION 2) of Nitrogen is needed to convert 6.34 moles of Hydrogen into ammonia.
