1. Unless otherwise instructed, you may use the periodic table in the Chemistry: Problems and Solutions book for this quiz. To answer this question, use the hydrazinenitrogen tetroxide rocket fuel reaction: 2N2H4 + N2O4 3N2 + 4H2O You are given 96 g of N2H4 and 92 g of N2O4. How many grams of N2 will this reaction produce? Hint: This is a limiting reactant problem. (Points : 1) 42 g 63 g 84 g 126 g 2. For the Haber process, N2 + 3H2 2NH3, which mole ratio would you use to calculate the yield of ammonia when given hydrogen? (Points : 1) 1 : 2 3 : 2 2 : 1 3 : 1 3. For the oxidation of glucose (C6H12O6 + 6O2 6H2O + 6CO2), how many moles of oxygen will it take to consume 6 moles of glucose? (Points : 1) 2 6 12 36 4. You are asked to make 112 g of iron from iron oxide and excess carbon monoxide. Fe2O3 (s) + 3CO (g) 2Fe (l) + 3CO2 (g) Approximately how many grams of iron oxide must you use? (Points : 1) 240 g 107 g 160 g 720 g 5. When calcium carbonate is heated, it breaks down into calcium oxide and carbon dioxide. CaCO3 (s) CaO (s) + CO2 (g) If you heat 25 g CaCO3, approximately what volume of carbon dioxide will you make? Assume the conditions of temperature and pressure are such that 1 mole of any gas will occupy 22.4 L. (Points : 1) 1.0 L 5.6 L 11.2 L 22.4 L
