3. Tuesday, March 19 th : “A” Day Wednesday, March 20 th : “B” Day (1:05 out) Agenda  Chapter 6 Tests  Go over ACT practice worksheets  Sweet 16 Chemistry Compound Tournament  “Riddled with Puns” worksheet Next time: Fun Labs Day!

4. Ch. 6 Tests “Covalent Compounds” ClassAverage Grade (out of 60) Average Percentage 1A52.5487.57% 3A51.9486.57% 2B53.3888.97% 3B53.2088.67%

5. ACT Practice Worksheets  I wanted to take some time to go over these ACT practice worksheets that you completed some time ago…

6. Sweet 16 Chemistry Compound Tournament  This worksheet is a fun play on the NCAA men’s division I basketball tournament, better known as “March Madness”.  This worksheet will incorporate things you learned in Chapter 5: “Ions and Ionic Compounds”, as well as molar mass.  You can use the “ion” app on the iPads and the “stable ions” charts that I gave you to help you complete the worksheet.

7. Sweet 16 Chemistry Compound Tournament Rules: 1 st round: write the formula after the name. The most number of atoms wins the bracket. 2 nd round: the greater number of ions wins the bracket. Semi-finals: higher charge on anion wins the bracket. Finals: larger molar mass wins the tournament!

8. Sweet 16 Chemistry Compound Tournament  Choose a partner, get your iPads, and we’ll do the first one together… 1 st Round Sodium acetate: Na only has 1 valence electron and will lose it to form a 1 + ion. Use “ion” app or table on pg. 178 of your book to find the acetate polyatomic ion. Na + + CH 3 COO - NaCH 3 COO

9. Sweet 16 Chemistry Compound Tournament Sodium acetate = NaCH 3 COO  Write the formula after the name…  How many atoms are there in the formula? 8  Remember, the most number of atoms wins the bracket. If potassium thiocyanate has less than 8 atoms in the formula, sodium acetate wins the 1 st bracket and advances to the 2 nd round.

10. Sweet 16 Chemistry Compound Tournament 2 nd Round  For the 2 nd round, the greater number of ions with the bracket.  Sodium acetate only has 2 ions (Na + and CH 3 COO - ) so if the other formula has more than 2 ions, sodium acetate will lose.

11. Sweet 16 Chemistry Compound Tournament Semi-finals  Look at the charge on the anion (the negative ion).  The most charge on the anion will advance to the final round.

12. Sweet 16 Chemistry Compound Tournament Finals  To win the tournament, the formula has to have the highest molar mass.  Remember, to find molar mass, just add up the mass of each element in the molecule.  Example: H 2 O: H: 2 (1.01) O: 16.000 18.02 g/mol

13. Sweet 16 Chemistry Compound Tournament  Have fun and work together to complete the worksheet!

14. “Riddled with Puns” Worksheet  With your partner, put your heads together and try to complete this worksheet…  Have Fun!
