Be sure to answer all parts. When powdered zinc is heated with sulfur, a violent reaction occurs, and zinc sulfide forms:
Zn(s) + Sg(s) → ZnS() (unbalanced]
(a) Some of the reactants also combine with oxygen in air to form zinc oxide and sulfur dioxide.
When 83.2 g of Zn reacts with 52.4 g of Sg, 109.3 g of ZnS forms. What is the percent yield of ZnS?
%
(b) If all the remaining reactants combine with oxygen, how many grams of each of the two oxides
form?
Mass Zno:
g
Mass SO2:
