In a blast furnace, iron(iii) oxide is used to produce iron by the following (unbalanced) reaction. fe2o3(s) + co(g) fe(s) + co2(g) (a) if 5.00 kg fe2o3 are available to react, how many moles of co are needed? mol (b) how many moles of each product are formed?

Hello!

A) The balanced chemical reaction is

Fe₂O₃(s)+ 3CO(g) → 2Fe(s) + 3CO₂(g)

We can use the following conversion factor to go from kg of Fe₂O₃ to moles of CO, in the following way:



So, the required amount of CO is 93,93 moles.

B) To calculate the moles of each product we'll use the following conversion factors to go from moles of CO to moles of product, using the reaction coefficients:



So, the moles of Fe are 62,62 and the moles of CO₂ are 93,93.

Have a nice day!
