2. Your question is….. Your question is….. How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? What now?! Set up the equation Give up Solve the problem

3. WRONG!!! Why?: You haven’t even set up the equation yet! (hint hint) Click here Click here to go back and try again! Click here

4. What makes you think you can do that?! Go to study tables… Smh Click here Click here to start over! Click here

5. Great Job.. And how would you do that?! Great Job.. And how would you do that?! How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water ? SO + H O H SO 2 2 2 3 SO + H O H SO 2SO + 2H O 2H SO 3 2 2 3 2 2 2 3

6. You really know your chemicals! What now? How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? Balance the equation 128g SO 1 2 128g H SO 2 3 1

7. WRONG!!! Why?: You have the wrong chemicals! (check your periodic table) Click here Click here to go back and try again! Click here

8. WRONG!!! Why?: The equation is already balanced! (use the laundry method to check) Click here Click here to go back and try again! Click here

9. Great job! What’s the next step? How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? 128g SO 1 2 1 2 1 mol SO 64.1g SO 2 2 1 mol SO 65g SO 2 2 128g SO 1 2 64.1g SO 1 mol SO 2 2 x x x

10. WRONG!!! Why?: Make sure you add up the chemicals correctly. (check the periodic table) Click here Click here to go back and try again! Click here

11. WRONG!!! Why?: During gfm you need to cancel out grams! Click here Click here to go back and try again! Click here

12. Great job! What’s the next step? How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? 128g SO 1 2 1 mol SO 64.1 g SO 2 2 x 128g SO 1 2 1 mol SO 64.1 g SO 2 2 x 2 3 2 mol H SO 1 mol SO 2 1 mol SO__ 1 mol H SO 2 3 2 128g SO 1 2 1 mol SO 64.1g SO 2 2 x 2 3 1 mol H SO 1 mol SO 2 x x x

13. WRONG!!! Why?: In the balanced equation, there is only one mole of Sulfurous Acid, not two! Click here Click here to go back and try again! Click here

14. WRONG!!! Why?: To cancel out the Sulfur Dioxide, it has to be placed in the denominator! Click here Click here to go back and try again! Click here

15. Super! What should we do next? Super! What should we do next? How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? g H SO 2 3 H SO 2 3 x 1 mol x H SO 2 3 1 mol

16. WRONG!!! Why?: You aren’t supposed to divide… I don’t even know what you’re thinking right now! For THAT kind of mistake, I’m going to have to make you START OVER! START OVER START OVER

17. WRONG!!! Why?: To end up with grams at the end of your equation, it needs to be in the numerator in your last section of the problem! Click here Click here to go back and try again! Click here

18. Alright, so how many grams would that be? Alright, so how many grams would that be? How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? 82 g 83 g 82.1 g

19. WRONG!!! Why?: Make sure you add up the chemicals correctly, using correct sig figs. (check the periodic table) Click here Click here to go back and try again! Click here

20. Okay smarty pants, what’s the final answer? Okay smarty pants, what’s the final answer? 164 g H2SO3 164 g SO2 165 g H2SO3 x 82.1g H SO 2 3 1 mol 128g SO 1 2 1 mol SO 64.1 g SO 2 2 x 2 3 1 mol H SO 1 mol SO 2 x

21. WRONG!!! Why?: Make sure you’re multiplying correctly, and using the correct amount of sig figs! Click here Click here to go back and try again! Click here

22. WRONG!!! Why?: You don’t even have the right ending chemical! Click here Click here to go back and try again! Click here

23. CONGRATS! You got it right!
