Question

Iron is obtained by reducing iron (III) oxide using the gas carbon monoxide. The reaction is
Fe2O3 + 3CO ------> 2Fe + 3CO2
a. write a word equation for the reaction
b. what is the formular mass of iron III oxide? (Fe 56, O 16)
c.How many moles of Fe2O3 are there in 320 kg iron III oxide
d. How many moles of Fe are obtained from 1 moles of Fe2O3
e. From c and d, how many moles of iron are obtained from 320kg of iron III oxide
f. how many iron in kg is obtained from 320kg of iron III oxide?

Answer 1

a. iron(III) oxide + Carbon-monoxide -> Iron + Carbon-di-oxide.
b.56*2 +16*3
c.Moles=mass(g) / Mr which is 3200/160
d. 2 moles
e.2 moles
f. Moles x Mr = mass so, 20 x 112=2240g
