Use the method of dividing moles by coefficients to determine whether the reaction is being run in
Question:
Use the method of dividing moles by coefficients to determine whether the reaction is being run in a balanced or limiting fashion. If it is being run in a limiting fashion and you are asked for theoretical yield, remember to use only the limiting reactant in your calculation.
Chemical treatment of zinc sulfide, ZnS, with oxygen, O2, gives zinc oxide, ZnO, and sulfur dioxide gas, SO2.
(a) Write a balanced equation for the reaction.
(b) If 10.0 g of ZnS is combined with 10.0 g of O2, what is the theoretical yield of each product, in grams?
(c) How much of the excess reactant is left over, in grams?
(d) Suppose only 7.50 g of ZnO is recovered. What is the percent yield of ZnO?
Step by Step Answer:
a Balanced Equation The balanced equation for the reaction is 2ZnSs 3O2g 2ZnOs 2SO2g This means that ...View the full answer
