  2. How Many Cookies Can I Make? • You can make cookies until you run out of one of the ingredients. • Once this family runs out of sugar, they will stop making cookies • (At least any cookies they will want to eat)

  3. How Many Cookies Can I Make? In this example, the sugar would be the limiting reagent, because it will limit the amount of cookies you can make. VIDEO: Cookie Monster

  4. Limiting Reagents • The limiting reagent is the reactant present in the smallest stoichiometric amount. (Example – water formation) • In other words, it’s the reactant you’ll run out of first.

  5. Practice • The most important commercial process for converting N2 from the air into nitrogen containing compounds is based on the reaction of N2 and H2 to form ammonia (NH3). • N2(g) + 3 H2(g) 2 NH3(g) • How many moles of NH3 can be formed from 3.0 mol of N2 and 6.0 mol of H2?

  6. Practice • The most important commercial process for converting N2 from the air into nitrogen containing compounds is based on the reaction of N2 and H2 to form ammonia (NH3). • N2(g) + 3 H2(g) 2 NH3(g) • How many moles of NH3 can be formed from 3.0 mol of N2 and 6.0 mol of H2? • Method: Reactant Know/Need Chart

  7. Practice You combine 10.0 grams of hydrogen gas and 15.0 grams of oxygen gas. How many grams of water vapor are made? Which, if any, is your limiting reagent?
