  1. StoichiometryAshley ThomsonPeriod 8April 10, 2011 Begin!

  2. Here’s the problem: Hydrochloric acid is added to 50.0g of iron (II) sulfide. What weight of hydrogen sulfide is produced? FeS + HCl FeCl + H S 2 2 What’s next? Balance the equation, of course. I need a hint. Ask Mr. Kirk!

  3. Hydrochloric acid is added to 50.0g of iron (II) sulfide. What weight of hydrogen sulfide is produced?FeS + HCl FeCl + H S 2 2 FeS + 2HCl FeCl + H S Now that you’ve balanced the equation, what’s next? 2 2 50.0g FeS 1 50.0g FeS 1 mol FeS 1 50.0g FeS

  4. Hydrochloric acid is added to 50.0g of iron (II) sulfide. What weight of hydrogen sulfide is produced?FeS + 2HCl FeCl + H S 2 2 Woo! You figured it out! Nice job. ;) One step down, a couple more to go. But can you do the next step? x ? 50.0g FeS 1 1 mol FeS 50.0 g FeS 1 mol FeS 87.913g FeS 1 mol FeS 87.9g FeS

  5. Hydrochloric acid is added to 50.0g of iron (II) sulfide. What weight of hydrogen sulfide is produced?FeS + sHCl FeCl + H S 2 2 Nice job! You’ve made it this far, so why stop now? What’s next? x ? 50.0g FeS 1 1 mol FeS 87.9g FeS x 1 mol FeS 1 mol HCl 1 mol FeS 1 mol H S 1 mol H S 1 mol FeS 2 2

  6. Hydrochloric acid is added to 50.0g of iron (II) sulfide. What weight of hydrogen sulfide is produced?FeS + 2HCl FeCl + H S 2 2 You’re on a roll! If you can do this one, then you’re almost done! So tell me, what do you do next? x ? 50.0g FeS 1 1 mol FeS 87.9g FeS 1 mol H S 1 mol FeS x x 2 1 mol H S 34.1g H S 34.1g H S 1 mol H S 1 mol H S 33.1g H S 2 2 2 2 2 2

  7. Answer: 50.0g FeS 1 1 mol FeS 87.9g FeS 1 mol H S 1 mol FeS 34.1g H S 1 mol H S x x x 2 2 = 2 19.4 g H S 2 Click me!

  8. YOU DID IT! Congrats! Have a party hat! :D Buhh- bye now!

  13. I gave my last hint away for that kid right before you, who didn’t know what he was doing either. Let’s try this again. Let’s try this again.

  14. Mr Kirk says: “If you don’t understand, I guess I’ll see you in study sessions soon.” I don’t think he wants to help at the moment, but if you listen to him and come in during study sessions, he’d be more then happy to help. Let's try this again.
