Heating an ore of antimony (Sb2S3) in the presence of iron gives the element antimony and iron(II) sulfide.
Sb2S3(s) + 3Fe(s) ---> 2Sb(s) + 3FeS(s)
When 15.0 g Sb2Sb3 reacts with an excess of Fe, 9.84 g Sb is produced. What is the percent yield of this reaction?
Here is a worked example of a stoichiometry problem. Just follow the steps.
