Iron (III) oxide reacts with carbon monoxide to form iron and carbon dioxide. Fe2O3 + CO  Fe + CO2 3 2 3 How many CO molecules are required to react with 25 particles of Fe2O3?

Iron (III) Oxide reacts with carbon monoxide to form iron and carbon dioxide. Fe2O3 + CO  Fe + CO2 3 2 3 How many iron atoms can be produced by the reaction of 2.5 x 105 particles of Fe2O3?

STOICHIOMETRIC RELATIONSHIPS Formulas can also represent MOLES of substances involved in chemical reactions. Equations define reaction ratios, i.e. the molar ratios of reactants and products

What mass of CO is required to react with 146 grams of iron (III) oxide? Fe2O3 + 3CO  2Fe + 3CO2

What mass of iron (III) oxide is required to produce 8 What mass of iron (III) oxide is required to produce 8.65 grams of carbon dioxide? Fe2O3 + 3CO  2Fe + 3CO2
