  2. 12.1 • How are mole ratios used in chemical calculations?

  3. 12.1a • In chemical calculations, mole ratios are used to convert between moles of reactant and moles of product, between moles of reactants, or between moles of products.

  4. 12.2 • Balance this equation: • C2H5OH(l) + O2 (g) → CO2 (g) + H2O(g

  5. 12.2a • C2H5OH(l) + 3O2 (g) → 2CO2 (g) + 3H2O(g)

  8. 12.4 • What is the percent yield if 4.65 g of copper is produced when 1.87 g of aluminum reacts with an excess of copper(II) sulfate • 2Al(s) + 3CuSO4 (aq) → Al2 (SO4) 3 (aq) + 3Cu(s)

  9. 12.4a • 70.43%

  10. 12.5 • The combustion of acetylene gas is represented by this equation:  • 2C2H2 (g) + 5O2 (g) → 4CO2 (g) + 2H2O(g) • How many grams of H2O are produced when 52.0 g C2H2 burns in oxygen?
