  1. Stoichiometry Tutorial By Bobby Woods

  2. In a complete combustion reaction, 250 kg of methane(CH4) reacts. How many kilograms of carbon dioxide is released? What do you do first? Find the gfm of CH4 Create an Equation Convert kilograms to grams

  3. In a complete combustion reaction, 250 kg of methane(CH4) reacts. How many kilograms of carbon dioxide is released? Which is the correct complete equation? CH4 + H2O  CO2 + O2 CH4 + O2 CO2 + H2O CO2 + H2O  CH4 + O2

  4. What do we do now? Convert kg to moles Convert kg to grams Balance the equation

  5. Which is correctly balanced? CH4 + 2O2  CO2 + 2H2O CH4 + 3O2  2CO2 + 2H2O 2CH4 + 4O2 2CO2 + 8H2O

  6. What’s next? Find the gfm of CH4 Test theory of relativity Convert kg to grams

  7. 250kg CH4 x 1000 g CH4 1 1 kg CH4 What’s next? Use grams CH4 to get moles CH4 Use moles CH4 to get gfm CH4 Use gfm to get moles CH4

  8. 250kg CH4 x 1000 g CH4 x 1 mole CH4 1 1 kg CH4 16.0g CH4 What’s next? Convert moles to liters Use mole to mole conversions to get to CO2 Ask Mr. Kirk

  9. 250kg CH4 x 1000 g CH4 x 1 mole CH4 x 1 mole CO2 1 1 kg CH4 16.0g CH4 1 mole CH4 What’s next? Use gfm to get grams to mole. Use gfm to get moles to grams. Use gfm to convert pounds to ounces.

  10. 250kg CH4 x 1000 g CH4 x 1 mole CH4 x 1 mole CO2 x 44g CO2 1 1 kg CH4 16.0g CH4 1 mole CH4 1 mole CO2 What’s next? Find the answer. Calculate sig figs Convert grams to kg.

  11. 250kg CH4 x 1000 g x 1 mole CH4 x 1 mole CO2 x 44g CO2 x 1 kg 1 1 kg 16.0g CH4 1 mole CH4 1 mole CO2 1000 g So what’s the answer? 68.75g CO2 68.75kg CO2 68g CO2 68 kg CO2

  12. You win!!!!!!!! That is the average amount of CO2 released by a car in 4 days.
