28.) If 15.0 grams of Hg react with 20.0 grams of O2 , what mass of HgO is formed? Pd 5 Chemistry March 18, 2010
1. What’s First? Start the ratio Balance the equation Write the equation
1. Correct Go to the Next part of the Question!!!
1. Incorrect • Hint: What do we need to figure out the moles part of the stoichiometry problem… Go Back to 1st Q
2. What’s the CORRECT equation? Hg Hg + O2 Hg + O2HgO 2Hg + O2 2HgO
2. Correct Go to the Next part of the Question!!!
2. Incorrect • Hint: Is the equation balanced. Go Back to 2st Q
3. If 15.0 grams of Hg react with 20.0 grams of O2 , what mass of HgO is formed? What’s FIRST?
3. Correct Go to the Next part of the Question!!!
3. Incorrect • Hint: Are all the numbers correct in the ratio equation? Go Back to 3st Q
4. Correct Go to the Next part of the Question!!!
4. Incorrect • Hint: Look at the element, amount, and where they are placed on the ratio equation. Go Back to 4st Q
5. Answer for Hg… 16.2 g HgO NEXT
6. If 15.0 grams of Hg react with 20.0 grams of O2 , what mass of HgO is formed? And then…And then…And then… And then… And then… Have to start Stoichiometry for O2 We are done Hg is limiting
6. Correct Go to the Next part of the Question!!!
6. Incorrect • Hint: What do we need to decide if something is limiting Go Back to 6st Q
7. If 15.0 grams of Hg react with 20.0 grams of O2 , what mass of HgO is formed? Next?
7. Correct Go to the Next part of the Question!!!
7. Incorrect • Hint: Look at the element, amount, and where they are placed on the ratio equation. Go Back to 7st Q
8. The Answer is… 270.7 g HgO NEXT
Which Is Limiting??? Hg= 16.2 g HgO O2 =270.7 g HgO
Incorrect • Hint: The smaller number is limiting because there less of that element to use. Go Back
Correct YAY!!!! We’re done
