Science 8:  We completed section B of the Heat Lab, Radiation.  Due next class is your graph of Temperature vs Time for heating water by radiation.  We watched this clip to try to understand why it is colder in the winter.

Chemistry 12:  Today we reviewed the difference between the solubility and Ksp by going through Unit 3 # 67.  We looked at #67 on page 99 and I asked these questions:

1) T/F: the Ksp of Mn(IO3)2 is 4.78 x 10^-3.   (... times 10 to the power of negative 3)

2) Write the Ksp expression for Mn(IO3)2.

3) If you needed a bottle with Mn2+ ions from our lab, what compound would you search for?

4) Determine the concentration of each ion in 0.0200 M KIO3.

5) Determine the concentration of each ion in 0.00478 M Mn(IO3)2

We added Unit 3 # 64, 65, 67 and 68 onto Unit 3 # 56-63, then we did the WS titled Solubility Review.

Chemistry 11:  After completing the Balancing Minireview WS #2, we learned the principles of Stoichiometry (Read pgs 123 and 124).  Due next class is the Stoichiometry WS (Moles only).
