10. Consider the following reaction: a) Balance the reaction. ZnS (s) + O₂(g) → Zn0(s) + SO₂(g) b) If you have 2.36 g ZnS and 2.25 g 02, which is the limiting reactant? What would be the theoretical yield of SO2 in this situation? c) If the average percent yield for the reaction in 3a is 85%, how much actual SO2 should you expect?

For the Shaefer-Fulton endospore stain method, the working solution of safranin is made by combining 10 mL of stock solution with 90 mL of distilled water. If you need to produce 1,046 mL of working solution, how many grams of safranin O will be required to make the smallest batch of stock solution possible? • Report your answer in grams using standard decimal notation rounded to two decimal places. • Include trailing zeros. • Do not include the units in your answer 。 If your answer is 100.105 g it would be reported as 100.11 。 If your answers was 100.203 g it would be reported as 100.20

INSTRUCTIONS 1. Please enumerate all given values. 2. Identify all unknown values 3. Write the formula first before substituting the values. 4. Enclose final answers in boxes. 5. Do not round off immediately. Consider the whole value during computations. 6. Round off final answers to 2 DECIMAL PLACES ONLY.
