2. The Question How many grams of NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ?

3. N 2 + H 2 NH 3 What do you do next? Solve problem? Balance the equation? Continue on with setting up the problem?

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 NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 Now that we’re balanced, what’s next? Go to answer? Convert grams to moles? Quit?

7. Right! How many grams of NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 25gH 2 x 1mol 1 2.0gH 2 What do you do next? Moles of H 2 to grams of NH 3 Ask Kirk? Quit?

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 NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 25gH 2 x 1mol x 2gNH 3 1 2.0gH 2 3molH 2 Next? Quit? Answer? Moles of NH 3 to grams of NH 3

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 NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 25gH 2 x 1mol x 2gNH 3 x 17.0gNH 3 1 2.0gH 2 3molH 2 1molNH 3 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 NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 25gH 2 x 1mol x 2gNH 3 x 17.0gNH 3 = 140gNH 3 1 2.0gH 2 3molH 2 1molNH 3 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 NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 25gH 2 x 1mol x 2gNH 3 x 17.0gNH 3 = 140gNH 3 1 2.0gH 2 3molH 2 1molNH 3 So, ready for more conversions? What’s the next step? Grams of N 2 to moles of N 2 Nothing. Moles to grams?

16. Keep trying. Continue? Previous slide?

17. Good Job. How many grams of NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 25gH 2 x 1mol x 2gNH 3 x 17.0gNH 3 = 140gNH 3 1 2.0gH 2 3molH 2 1molNH 3 28gN 2 x 1molN 2 x 1 x 28.0gN 2 Next? Moles of N 2 to moles of NH 3 Go to answer? Moles of N 2 to Grams of NH 3

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

19. I’m so proud. How many grams of NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 25gH 2 x 1mol x 2gNH 3 x 17.0gNH 3 = 140gNH 3 1 2.0gH 2 3molH 2 1molNH 3 28gN 2 x 1molN 2 x 2molNH 3 x 1 x 28.0gN 2 1molN 2 What now? Moles of NH 3 to grams of NH 3 Answer? Quit?

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 NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 25gH 2 x 1mol x 2gNH 3 x 17.0gNH 3 = 140gNH 3 1 2.0gH 2 3molH 2 1molNH 3 28gN 2 x 1molN 2 x 2molNH 3 x 17.0gNH 3 1 x 28.0gN 2 1molN 2 1molNH 3 What are you gonna do next? Ask Kirk? Quit? Final answer?

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 NH 3 can be produced from the reaction of 28g of N 2 and 25g of H 2 ? N 2 + 3H 2 2NH 3 25gH 2 x 1mol x 2gNH 3 x 17.0gNH 3 = 140gNH 3 1 2.0gH 2 3molH 2 1molNH 3 28gN 2 x 1molN 2 x 2molNH 3 x 17.0gNH 3 = 34gNH 3 1 x 28.0gN 2 1molN 2 1molNH 3
