1. Pd 5 Chemistry March 18, 2010

2. Balance the equation Write the equation Start the ratio

3. Go to the Next part of the Question!!!

4.  Hint: What do we need to figure out the moles part of the stoichiometry problem… Go Back to 1 st Q

5. 2Hg + O 2 2HgO Hg + O 2 HgO Hg Hg + O 2

6. Go to the Next part of the Question!!!

7.  Hint: Is the equation balanced. Go Back to 2 st Q

8. What’s FIRST?

9. Go to the Next part of the Question!!!

10.  Hint: Are all the numbers correct in the ratio equation? Go Back to 3 st Q

12. Go to the Next part of the Question!!!

13.  Hint: Look at the element, amount, and where they are placed on the ratio equation. Go Back to 4 st Q

14. NEXT

15. And then…And then…And then… And then… And then… Have to start Stoichiometry for O 2 We are done Hg is limiting

16. Go to the Next part of the Question!!!

17.  Hint: What do we need to decide if something is limiting Go Back to 6 st Q

18. Next?

19. Go to the Next part of the Question!!!

20.  Hint: Look at the element, amount, and where they are placed on the ratio equation. Go Back to 7 st Q

21. 270.7 g HgO NEXT

22. O 2 =270.7 g HgO Hg= 16.2 g HgO

23.  Hint: The smaller number is limiting because there less of that element to use. Go Back

24. YAY!!!! We’re done
