Mr. Scully TAKE 2

  • Hey guys. I'll keep the shenanigans to a minimum today, due to request by Dr. B
  • One thing to remember: If doing multiple parts to one question, don't round your first answer when applying it to the second part of the problem. YOU COULD MAKE A MISTAKE. Not that I expect that to happen. You are all very bright students: Hence the honors chemistry.

  • OH! Don't forget: Finish the packet, oh ye who hath suffered lack of knowledge of its due...ness.

  • Also for homework: PAGES 252-253. NUMBAS 28,29,30,31,32,and 33

  • Ok, back to the information: It is useful to know the percentage by mass of a particular element in a chemical compound.

  • Why? I don't know. But here's how you find it=

  • % of element = 100 * (Mass of that particular element / mass of the whole compound)

  • Exams are coming up, and I know studying sounds lame... but it's important.

  • Yes, Michael Scully is actually telling someone to study. Shocking, I know.

  • But Even Though You Want to Give up, You must KEEP ON!

  • I know what you're thinking. You think that the quarter is over.
Over? Did you say "over"? Nothing is over until we decide it is! Was it over when the Germans bombed Pearl Harbor? Heck no! And it ain't over now. 'Cause when the goin' gets tough... the tough get goin'! Who's with me? Let's go! Ace these quizzes, Master The Material, Go Out There, And Make Yourself Proud! You've worked too hard to let the end of the quarter kill your grade. We can do this, guys. We're smart. That's why we were chosen for the Honors Track. Because the work's harder, but we can handle it! Be smart. Be strong.

  10. Yeah!!! I'm ready to revolutionize something.

    Scully... You are great!!! (Except for the fact that the Germans didn't bomb Pearl Harbor, it was the Japanese. Sorry.)
