Q2) Hematite, Fe2O3, is an important ore of iron. The free metal is obtained by reacting hematite with excess carbon monoxide, CO2, in a blast furnace. Carbon dioxide is formed in the furnace by partial combustion. The unbalanced reaction is: Fe 0; (3) + CO(g) + Fe (8) + CO2(g) How many grams of iron can be produced from placing 1.50 kg of Fe,0, in a blast furnace?
1. To get iron out of iron ore (the stuff that actually comes out of the ground), you need to heat it with charcoal (C). The reaction is: 2(Fe2O3) + C .......... 4 Fe + 3 (CO2) How many kilograms of iron would you produce by processing 15.00 kg of iron ore? 2.
