Fe2O3 + CO → Fe + CO2 If 2 moles of Fe2O3 react with 9 moles of CO, how many moles of each product are formed? (3 points)

The number of moles of each product that are formed if 2 moles of Fe2O3 react with 9 moles of CO is 4 moles of Fe and 6 moles of CO2

Explanation

write a balanced chemical reaction

that is FeO3 + 3 CO → 2 Fe + 3CO2

2 moles of Fe2O3 reacted with 3 x2=6 moles of Co to form Fe and CO2 therefore CO was in excess and Fe2O3 was limiting reagent.

use the mole ratio to determine the moles of each product.

that is the mole ratio 0f Fe2O3 : Fe is 1:2 therefore the moles of Fe = 2x2=4 moles

the mole ratio of Fe2CO3 : CO2 is 1: 3 therefore the moles of Co2 = 2 x3 = 6 moles
