Answer:
Explanation:
Iron(III) oxide gets mixed with elemental carbon and heated to make elemental iron and carbon dioxide.
2Fe₂O₃ + 3C = 4 Fe + 3 CO₂
2 x 160 3 x 12 4 x 56
320 gram of iron ( iii ) oxide requires 36 g of carbon for reduction
1 kg of iron will require 36 / 320 g of carbon
carbon required = 36 / 320 g
= .1125 g
= .113 g rounding off to 3 significant fig .
b )
320 gram of iron ( iii ) oxide produces 224 g of iron after reduction
1 g of iron will produce 224 / 320 g of iron
iron produced = 224 / 320 g
= 0.700 g .
