  1. Stoichiometry By: Destina Slone May 9, 2011

  2. How much ammonium hydroxide is needed to react completely with 75.0g of copper (II) nitrate in a double replacement reaction? What do we do first? Create the equation. Balance the equation. Nothing, were finished.

  3. How much ammonium hydroxide is needed to react completely with 75.0g of copper (II) nitrate in a double replacement reaction? Correct. Now which is the correct balanced equation? NH4OH+Cu(NO3)2NH4(NO3)+Cu(OH)2 NH+OH+Cu(NO3)2NH4(NO3)+Cu(OH)2 2NH4OH+Cu(NO3)22NH4(NO3)+Cu(OH)2

  4. WRONG! Panic? Retry

  5. Oops! Wrong ! Panic?

  6. How much ammonium hydroxide is needed to react completely with 75.0g of copper (II) nitrate in a double replacement reaction? THAT’S RIGHT! 2NH4OH+Cu(NO3)22NH4(NO3)+Cu(OH)2 What do we do now? 75.0gCu(NO3)2 1 1 mol Cu(NO3)2 75.0gCu 1gCu(NO3)2 75.0

  7. Are you crazy? Let us try this again. Panic?

  8. How much ammonium hydroxide is needed to react completely with 75.0g of copper (II) nitrate in a double replacement reaction? 2NH4OH+Cu(NO3)22NH4(NO3)+Cu(OH)2 Great job! But can you do what’s next? x 75.0gCu(NO3)2 1 1 mol Cu (NO3)2 187.5gCu(NO3)2 187.5g Cu (NO3)2 1 mol Cu(NO3)2 1 mol (NO3)2 187.5 g Cu(NO3)2

  9. NO! Sorry. Panic? Give it another go?

  10. How much ammonium hydroxide is needed to react completely with 75.0g of copper (II) nitrate in a double replacement reaction? 2NH4OH+Cu(NO3)22NH4(NO3)+Cu(OH)2 WOW! You’re good! But do you know what’s next? x 1 mol Cu (NO3)2 187.5gCu(NO3)2 x 75.0gCu(NO3)2 1 1molNH4 2 mol NH4 2molCu(NO3)2 1molNH4OH 2molNH4OH 1molCu(NO3)2

  11. That’s wrong! But don’t give up! You’re so close! Panic?

  12. How much ammonium hydroxide is needed to react completely with 75.0g of copper (II) nitrate in a double replacement reaction? WOW! Great! 2NH4OH+Cu(NO3)22NH4(NO3)+Cu(OH)2 Um…now what? x x 1 mol Cu (NO3)2 187.5gCu(NO3)2 2molNH4OH 1molCu(NO3)2 x 75.0gCu(NO3)2 1 20gNH4OH 1molNH4OH 35gNH4OH 1molNH4OH 1molNH4OH 35gNH4OH

  13. Incorrect! Panic? Redo!

  14. How much ammonium hydroxide is needed to react completely with 75.0g of copper (II) nitrate in a double replacement reaction? Perfect! You’re amazing! Now what is the answer? x x 1 mol Cu (NO3)2 187.5gCu(NO3)2 2molNH4OH 1molCu(NO3)2 35gNH4OH 1molNH4OH =? x 75.0gCu(NO3)2 1 24.0 gNH4OH 28.0 gNH4OH 100.0 gNH4OH

  15. Missed it on the last question? You can do this. Panic?
