  1. Stoichiometry Finding quantities in chemical reactions

  2. C3H8 + 502 --> 3CO2 + 4H2O • If there are two moles of oxygen available, which mole ratio will tell you how much water is produced? • A: 4 mol H20/1 mol O2B: 5 mol O2/4 mol H2O

  3. C3H8 + 502 --> 3CO2 + 4H2O • If there are 10 moles of C3H8, which mole ratio will tell you how much oxygen is required for the reaction to take place? • A: 1 mol C3H8/5 mol O2B: 5 mol O2/3 mol C3H8

  4. C3H8 + 502 --> 3CO2 + 4H2O • Which ratio will tell you how much water is produced from the combustion of .5 moles of C3H8? • A: 1 mol C3H8/4 mol H2OB: 2 mol H2O/1 mol C3H8

  5. 4Al + 3O2 --> 2Al2O3 • Which mole ratio describes how much oxygen is required to produce 10 moles of product? • A: 2 mol Al2O3/3 mol O2B: 3 mol O2/3 mol Al2O3

  6. 4Al + 3O2 --> 2Al2O3 • Which mole ratio tells you how much product is produced from three moles of aluminum? • A: 2 mol Al2O3/4 mol AlB: 3 mol Al/2 mol Al2O3

  7. ZnO + 2HCl --> ZnCl2 + H2O • Which mole ratio tells you how to find the amount of water produced from two moles of zinc oxide? • A: 1 mol H2O/1 mol ZnOB: 1 mol ZnO/1 mol H2O

  8. ZnO + 2HCl --> ZnCl2 + H2O • Which mole ratio tells you have to find how much HCl is required to get 8 moles of ZnCl2? • A: 4 mol HCl/1 mol ZnCl2B: 1 mol ZnCl2/2 mol HCl

  9. ZnO + 2HCl --> ZnCl2 + H2O • Classify the above reaction. • A: synthesisB: decompositionC: single replacementD: double replacementE. combustion
