Practice Problems: Fe2O3 + 3 CO → 2 Fe + 3 CO2 How many moles of carbon dioxide (CO2) can be made from 7.25 moles of CO? How many moles of Iron (III) oxide must be used to produce 4.5 moles of iron? Balance the equation first: C2H4 + O2  CO2 + H2O How many moles of water will be produced from 3.0 moles of oxygen? How many moles of C2H4 are needed to create 1.35 moles of carbon dioxide?

Practice Problems Answer Key 7.25 moles CO2 2.3 moles Fe2O3 2.0 moles H2O 0.675 moles C2H4
