  1. Stoichiometry By: Cierra Frymark

  2. The Question How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2?

  3. How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + H2 NH3 What do you do next? Solve problem? Continue on with setting up the problem? Balance the equation?

  4. Uh, no. That is NOT the right answer.  What do you think you’re doing, kid? What is your next bright idea? Go back to last slide?

  5. Why would you even think this would be the answer? Frustrated yet? Time to continue! What’s next? Previous slide?

  6. You are Correct! Congrats.  How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 Now that we’re balanced, what’s next? Go to answer? Quit? Convert grams to moles?

  7. Right!  How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 25gH2 x 1mol 1 2.0gH2 What do you do next? Moles of H2 to grams of NH3 Quit? Ask Kirk?

  8. I’d like you to rethink that one, please. Alright, I’ll give you another chance. What are you thinking you should do now? Previous slide?

  9. Yay! Another correct answer  How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 25gH2 x 1mol x 2gNH3 1 2.0gH2 3molH2 Next? Quit? Answer? Moles of NH3 to grams of NH3

  10. I think you might of taken a wrong turn, kid. What would you like to do? Previous slide?

  11. You’re doing great! How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 25gH2 x 1mol x 2gNH3 x 17.0gNH3 1 2.0gH2 3molH2 1molNH3 What now? Grams to moles? Answer? Ask Kirk?

  12. That was a stupid move, not gonna lie.  Get your head in the game, son! What’s your next call? Previous Slide?

  13. Correct! How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 25gH2 x 1mol x 2gNH3 x 17.0gNH3 = 140gNH3 1 2.0gH2 3molH2 1molNH3 Are you done? Yes. No.

  14. Wrong, again.  Today jut isn’t your day. What’s next? Previous slide?

  15. Smart choice. How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 25gH2 x 1mol x 2gNH3 x 17.0gNH3 = 140gNH3 1 2.0gH2 3molH2 1molNH3 So, ready for more conversions? What’s the next step? Grams of N2 to moles of N2 Nothing. Moles to grams?

  16. Keep trying. Continue? Previous slide?

  17. Good Job. How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 25gH2 x 1mol x 2gNH3 x 17.0gNH3 = 140gNH3 1 2.0gH2 3molH2 1molNH3 28gN2 x 1molN2 x 1 x 28.0gN2 Next? Go to answer? Moles of N2 to moles of NH3 Moles of N2 to Grams of NH3

  18. Not quite. Better try again. Previous slide?

  19. I’m so proud. How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 25gH2 x 1mol x 2gNH3 x 17.0gNH3 = 140gNH3 1 2.0gH2 3molH2 1molNH3 28gN2 x 1molN2 x 2molNH3 x 1 x 28.0gN2 1molN2 What now? Moles of NH3 to grams of NH3 Quit? Answer?

  20. Really? How many times are you gonna make a mistake? Ha! Keep going, you’ll get there. Previous slide?

  21. Right again! How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 25gH2 x 1mol x 2gNH3 x 17.0gNH3 = 140gNH3 1 2.0gH2 3molH2 1molNH3 28gN2 x 1molN2 x 2molNH3 x 17.0gNH3 1 x 28.0gN2 1molN2 1molNH3 What are you gonna do next? Ask Kirk? Final answer? Quit?

  22. Don’t fall asleep on me! C’mon! Keep pulling through, you’ll get it! Previous slide?

  23. Congratulations, you finish a stoichiometry problem. 

  24. You made it all the way through, don’t you feel good? How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2? N2 + 3H2 2NH3 25gH2 x 1mol x 2gNH3 x 17.0gNH3 = 140gNH3 1 2.0gH2 3molH2 1molNH3 28gN2 x 1molN2 x 2molNH3 x 17.0gNH3 = 34gNH3 1 x 28.0gN2 1molN2 1molNH3
