Question

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)

if 4.00 kg Fe2O3 are available to react how many moles of CO are needed? how many moles of each product are formed?

help please how do i balance this?

Answer 1

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

Convert 4.00 kg Fe2O3 to moles. moles = grams/molar mass.
Now look at the balanced equation. 1 mole Fe2O3 requires 2 moles CO and produces 2 moles Fe and 2 moles CO2.
