different chemical properties of each compound. We will accomplish this by a separation procedure known as distillation‚ which relies on each compound having a distinct and separate boiling point. Our pure products will be analyzed with gas chromatography to determine the success of the distillation. Procedures The experiment was performed as stated in the course textbook: Pavia‚ D.

mean "How important can toilet paper be‚ after all?" Even its very definition given in the Webster’s New Century Dictionary an absorbent paper‚ usually wound around a cardboard cylinder‚ for cleansing after defection or urination sounds...dirty. Who would pay attention or value something that is dirty? Well‚ let me tell you something‚ ladies and gentlemen‚ the whole society has a problem with appreciating little things in life. It’s the same thing with the toilet paper‚ other called toilet tissue-

TPFormatV07 TERM PAPER FORMAT 2003 11 03 INTRODUCTION The preparation of a research paper -- be it for a class term paper‚ a professional journal article‚ a technical report at a job‚ or a graduate thesis -- may generally be divided into five tasks: (1) identifying the problem or question to be dealt with; (2) collecting data (measured observations and/or bibliographic references) about the problem or question; (3) analyzing the data‚ either by statistical examination of the observations‚

CHAPTER I INTRODUCTION Background of the study This investigation was chosen to serve as a guide for people to know how one recycles paper. One of the things we use most often— especially in school — is paper. It takes about 20‚ 000 trees to make the Saturday edition of a big city newspaper. Therefore we use unimaginable amounts of paper a day. This study can help us to reduce‚ reuse‚ and recycle (ecokids.ca/pub/fun_n_games/printables/activities/assets/science_nature/paper_making.pdf) Significance

experience the release of excess gases within a thirty-minute time period. The white light experienced the most success by concluding the thirty minutes with eight floating disks out of ten. The Activity of Photosynthetic Pigments Silica gel chromatography can be used to determine what light wavelengths are used for photosynthesis. In this experiment‚ chlorophyll a‚ chlorophyll b‚ carotene‚ and xanthophyll were tested. The distance moved by molecule and the distance moved by the solvent is used

Beam Chopping corrects for flame emission but not for scattering. Can distinguish the signal of the flame from the atomic line at the same wavelength. The higher the absorbance the higher the transmittance. Intro to IR Near IR- (0.78 to 2.8 micrometers) Mid IR- (2.5- 50 micrometers) Far IR- (50-1000 micrometers) Most common region used is Mid IR btwn 2.5- 15 micrometers Mid IR: based on diffracting gratings but now current instrumentation are of Fourier transform type Far-IR: useful
