One of the reactions that occurs in a blast furnace, where iron ore is converted to cast iron, is below.
Fe2O3 + 3 CO 2 Fe + 3 CO2
Suppose that 1.86 103 kg of Fe are obtained from a 5.98 103 kg sample of Fe2O3. Assuming that the reaction goes to completion, what is the percent purity of Fe2O3 in the original sample?
This is exactly the same process as in your previous problem. The only difference is that instead of given a reactant and you calculate the product, in this case you are given the product and you must calculate the reactant. By the way you need to find your arrow key. --> or ==> or >>>
