#1 --Please finish your lab worksheets from class.  The solutions are printed in the teacher portion of the lesson.  If you need more help understanding mole conversions, see your textbook, chapter 6.4, or a video-tutor like http://socratic.org/chemistry/the-mole-concept/what-is-a-mole -  see the bottom of the page (chapter 15).   See also below.

#2 --Learn the Song!  and think of some good ideas for taping it {I have this cool lamb puppet, which could sing "Baaaaaaaaaaa-rium is 56..." --I will bring my lamby, plus some hellium balloons, some glow in the dark face paint..}  Anyone got a Frankenstein mask?  leave comments with ideas.

#4 --Covalent Bonding - naming practice - When a metal binds to a non-metal, it's ionic, but if two non-metals bind together, it is a genuine molecule with  covalent bonds, and it has a different and simpler method of naming.  Print out pages 10-11, read the directions and fill out the worksheet.  http://academic.pgcc.edu/~bsuitte/chem%201010/Nomenclature_Worksheets%20covers%20all.pdf

Congratulations -- we have done a lot of groundwork for success in chemistry, and hopefully it will get more and more interesting as time goes on and our knowledge base grows.  Good work, all round!


EC for IQ- Can you figure this one out?  (using dimensional analysis, factor-label, 'nother name for one, whatever you want to call it...)

Cardiovascular diseases are the leading causes of death worldwide.  To address this problem, bio-medical engineers have designed various artificial hearts, which surgeons may someday routinely implant in patients whose own hearts are failing.  Before implanting such a decide in a patient, a surgeon needs to have an idea of how long the artificial heart might be expected to work before needing to be replaced. If an artificial heart is capable of pumping at least 17,000,000 pints of blood before failure, how long will it probably last in a patient whose average heart rate is 72 beats per minute, and average stroke volume (the amount of blood pumped each stroke) is 70 ml?   [hint: there are about 473 mL per pint, and strokes are the same as heartbeats.]

1.  Plug in the value that you start with.
2.  Determine what unit you want to end up with. (how many years?)
3.  Write down any ratios that you are given.
4.  Write down any conversion factors that you might need.
Then make an extended t-chart.  Write your answer in comments.
Prize will be CANDY!
