4. Calculate the atom economy for the production of iron from iron(III) oxide in the blast furnace. Fe_(2)O_(3)+3COarrow 2Fe+3CO_(2)

## Step 1: First, we need to understand what atom economy is. Atom economy is a measure of the amount of starting materials that become useful products. In other words, it is the theoretical yield of the desired product divided by the total yield of all products, multiplied by 100%. ### The formula for atom economy is: ** **## Step 2: In this reaction, the desired product is iron (Fe). So, we need to calculate the molar mass of iron and the total molar mass of all reactants.### The molar mass of iron (Fe) is: ** **### The total molar mass of all reactants is: ** **## Step 3: Now, we can substitute these values into the atom economy formula to calculate the atom economy for the production of iron from iron(III) oxide.### The atom economy is: ** **
