  1. Reaction Stoichiometry

  2. Mole Ratio • Coefficients of a balanced chemical equation show us the ratio of molecules or moles in a chemical reaction • 2H2 + O2→ 2H2O • 2 molecules of hydrogen react with 1 molecule of oxygen to produce 2 molecules of water • 2 moles of hydrogen react with 1 mole of oxygen to produce 2 moles of water

  3. Example 1 • Chalcopyrite (CuFeS2) is the mineral source for pure copper. The equation is as follows: • 2CuFeS2 + 5O2→ 2Cu +2FeO + 4SO2 • How much copper can be produced from 1.00 g of chalcopyrite?

  4. Example 2 • How much water is produced from the combustion of 1.00 g of glucose, C6H12O6?

  5. Example 3 • Solid lithium hydroxide is used in space vehicles to remove exhaled carbon dioxide. The lithium hydroxide reacts with gaseous carbon dioxide to form solid lithium carbonate and liquid water. How many grams of carbon dioxide can be absorbed by each 1.00 g of lithium hydroxide?

  6. Example 4 • A common laboratory method form preparing small amounts of oxygen involves the decomposition of potassium chlorate to potassium chloride and oxygen. How many grams of oxygen can be produced from the decomposition of 4.50 g of potassium chlorate?
