Activity: How many grams of iron, Fe were formed by the reaction between iron(II) oxide, Feo and carbon, C, if the reaction also yielded 22 g of carbon dioxide, CO2? 22 g CO2 m, = ? g Fe First, on the basis of the given compounds' names, complete the balanced chemical equation: m = iron(II) oxide + carbon > iron + carbon dioxide + + Now, calculate the following masses mass of 2 moles of Fe = mol x ] 9 mol 9 1 mol x( g mol g mass of 1 mole of CO2 = mol-1) = g Finally, on the basis of this reaction, complete the proportion needed to calculate the mass of iron obtained. g Fe are formed simultaneously with So x g Fe are formed simultaneously with g g Co, gFe x gco
