Question

Based on the equation below , how many moles of carbon monoxide (CO) are needed to react completely with 1.75 moles of iron (lll) oxide (Fe2O3)

Fe2O3(s) + 3CO(g) --->2Fe(s) + 3CO2(g)

Answer 1

Well, we can use the factor-label system to convert from moles of iron (III) oxide to moles of carbon monoxide for this equation...\[1.75mol\ Fe_2O_3*(\frac{3mol\ CO}{1mol\ Fe_2O_3})=5.25mol\ CO\]
