Please answer question 21 part A
One day in lab, while taking apart a complicated distillation apparatus, your friend Maya (an expert chemist) says this:
"Metal sulfides roasted with oxygen produce the corresponding oxide and sulfur dioxide gas."
Using Maya's statement, and what you already know about chemistry, predict the products of the following reaction.
Be sure your chemical equation is balanced!

- The amount of sodium hypochlorite in a bleach solution can be determined by using a given volume of bleach to oxidize excess iodide ion to iodine; ClO- is reduced to Cl-. The amount of iodine produced by the redox reaction is determined by titration with sodium thiosulfate, Na2S2O3; I2 is reduced to I-. The sodium thiosulfate is oxidized to sodium tetrathionate, Na2S4O6. In this analysis, potassium iodide was added in excess to 5.00 mL of bleach (d=1.00g/cm3) .
