Atoms and More!!!!!

Hey there, sorry that i am posting this so late, band practice went a bit overboard......




Lauren couldn't do the blog tonight so I'll be subbing in for her. Today in class we tried to get the Homecoming Genie to come out, unfortunately he did not come out. Mr. Lieberman claims that the Genie was crying because of our lack of spirit......so tomorrow EVERYONE needs to wear blue and gold, COME ON AND LETS SHOW OUR SPIRIT!!!!!!!!!!
For those of you who weren't here in class or listening here are the equations for the Oleic Acid Lab problems.......

For the first question you would take the volume you got for the single drop of methanol and the oleic acid drop (aka .005) and multiply them together to get the volume of Oleic Acid per drop of solution.


For the second question the Surface Area of a circle is Pi (3.14159) radius squared.....


For the fourth question you would cross multiply the height (found in question 3) over the width equals 18/3 so the problem would look something like this..... h/w=18/3 and then you would cross multiply to get your answer.


For the fifth question you would multiply the length by the width by the height to get the volume.

For the sixth question you would just multiply the density by the volume to get the mass.



And finally the seventh question, the theoretical amount is given to you now you just have to do the work...... Actual (what you got) minus the theoretical over the theoretical times 100.


The other two questions don't need equations. Also this lab is due TOMORROW!!!!!! Some other things that are due tomorrow: The Rutherford Simulation lab, and the Chem think-isotopes (click on the Atom then click on Isotopes, remember to read the tutorial before answering the questions!!!!!!) Here is some home work that is not due tomorrow but was assigned.....The Web Assigns (they are now posted on the web assign website), and the Atomic Structure work sheet. I couldn't figure out a way to put the link in the post so I'll just give you the instructions......1st sign on to the moodle website 2nd go to Chem Honors 173 metacourse then click on the Unit 2 worksheet link and look of the pdf. file of the Atomic Structure worksheet.



Also in class today we took notes on the Atomic Structure.....
http://www.slideshare.net/gbsliebs2002/atomic-structure (sorry the thing wouldn't let me upload the file....and yes I tried both the embed code and the url).....geeze the blog won't let me upload a lot of things......



Oh the next scribe will be........Nirali P.!!!!!!!!!!!! Good luck to you!!!

P.S WEAR BLUE AND GOLD!!!!!!!!!!!!!!!!!!!!!!!!!
