Iron is extracted from iron ore (aka iron(III) oxide) by reacting it with carbon monoxide. Carbon dioxide is a by-product of this reaction. Suppose you are involved in the design of a steel plant and are concerned about its environmental impact. You need to know not only the amount of iron you can extract from the ore supplied, but also the amount of carbon dioxide released into the atmosphere during the production. What mass of carbon dioxide (in kg) will...
