In the preparation of iron from haematite `(Fe_2O_3)` by the reduction with carbon `Fe_2O_3+C rarr Fe+CO_2` how much `80%` pure iron may be produced from `120kg` of `90%` pure `Fe_2 O_3` ?

Iron is obtained on large scale from haematite Fe_(2)O_(3)

In the reaction x FeS_2 + yO_2 rarr Fe_2 O_3 + SO_2

Hematitic (Fe_(2) O_(3)) is an important ore of iron. The free metal (Fe) is obtained by reducing hematite with carbon monoxide (CO) in a blast furnace: Fe_(2)O_(3)(s) + 3CO(g) rarr 2Fe(s) + 3CO_(2) (g) How many grams of Fe can be produced from 1.00 kg Fe_(2) O_(3) ?

In the reaction of canadium oxide (VO) with iron oxide (Fe_2O_3) the products are V_2O_5 and FeO . How many grams of V_2O_5 can be formed from 2.00 g of VO and 5.75 g of Fe_2O_3 .
