  1. Stoichiometry

  2. Problem • If 16.8g of CO is mixed under high pressure with 1.78g of H2. What is the mass of ethanol (CH3OH)will be produced?

  3. What do you do first? • Balance the equation • CO g to methanol moles • H2 g to methanol moles

  4. CORRECT! • CO+H2 CH3OH • Which equation balances the reaction? CO+2H2  2CH3OH CO+2H2 CH3OH 3CO+3H2  2CH3OH

  5. INCORRECT! • Remember that you need to have both sides of the reaction equal before you can make an equation Try Again

  6. CORRECT • CO+2H2 CH3OH • What is next? Convert everything to moles Convert everything to grams • leave everything as it is

  7. INCORRECT TRY AGAIN

  8. INCORRECT! • Remember that you need to have both sides of the reaction equal before you can make an equation Try Again

  9. Correct

  10. SETTING UP THE EQUATIONSwhich is correct?

  11. SETTING UP THE EQUATIONS

  12. Which element is limiting?16.8gCo = 9.14gCH3OH1.78gH2 = 14.12gCH3OH CoH2

  13. INCORRECT, remember that the smaller number symbolizes a limiting reactant. And larger number will have an excessive amount

  14. Which element is excessive? 16.8gCo = 9.14gCH3OH1.78gH2 = 14.12gCH3OH CoH2

  15. CONGRATULATIONS • You now know how to do stoichiometry
