Iron is one of the very important moderately reactive metals.

Question

(i) Write a balanced equation for the top, middle and bottom of the furnace. [6marks]

Answer 1

Top of the furnace:
2Fe2O3(s) → 4Fe(s) + 3O2(g)

Middle of the furnace:
3CO(g) + Fe2O3(s) → 2Fe(s) + 3CO2(g)

Bottom of the furnace:
Fe3O4(s) + 4CO(g) → 3Fe(s) + 4CO2(g)
