a) In an experiment done carefully thus there is a 100% yield. 0.05 g of iron reacted with hydrochloric acid to give 0.145 g of a chloride FeCln. There are two chlorides of iron, ferrous chloride, FeCl2, and ferric chloride, FeCl3. Which one was obtained?
b) Presume the yield in the experiment had been less than 100%. Would the value of n have been greater or less than the value calculated by assuming 100% yield? Why?
