Grace Dammen Altitude Sickness Biology Honors 1st Quarter Project For every 1,000 feet ascended in elevation, there is a 3% oxygen decrease. Altitude sickness, formally known as Acute Mountain Sickness or high altitude pulmonary edema.occurs when there is lack of oxygen supply in the air due to high elevation. Altitude or elevation increases when sea level gets farther away

3. INTRODUCTION Organic compounds are isolated either from natural sources or from reactions mixtures. These compounds are seldom pure and are usually contaminated with small amounts of other similar compounds, which are found to exist together or formed during the reaction. In order to characterize them, it is important to purify them. 4. PROCESSES FOR PURIFICATION 1. Crystallization 2. Sublimation 3. Distillation 4. Chromatography 5. Differential Extraction 6. Qualitative Analysis 5. 1. CRYSTALLIZATION

De Ocampo, Yves Aaron Julian, Dela Vega, Roderick R. Jr., Elguira, Cedric Tristan D. Enriquez, Joanne B., Gabat, John Elliot Group 5, 2D Medical Technology, Faculty of Pharmacy, UST ABSTRACT Sublimation is a change directly from the solid to the gaseous state without becoming liquid. In this experiment, we used the process of sublimation to purify the impure benzoic acid. We obtained from 5.00 g to 2.30 g of the sublimate compound. After we purify the acid we collected the pure and sublimate

In this experiment, sublimation was used to purify solid mixtures. The compound used to undergo purification is impure benzoic acid. The product obtained after the heating process is called the sublimate in the form of crystals. The weight of the impure benzoic acid gave a lot of difference from the sublimate obtained from 5.0014 g to 0.3213 g, respectively. Thus, the measured sublimate showed the low percentage recovery of the said compound. The sublimate was then subjected to melting point determination

Wednesday, October 16th, 2013, Clara Kirk, a 72-year old woman, said she was having difficulties paying for two different gas and water bills at her shelters that she runs to provide for women and children in need. One of the bills was roughly $21,000 and another bill was around $11,000 (Hutson, 2013). Due to the fact that she was unable to take care of those bills, the gas was shut off on Wednesday, October 16, 2013. This left all of the helpless people without heat or hot water which forced

Introduction (Experiment 1) Distillation is a process involving the conversion of a liquid into a vapor that is later on condense back to liquid form for collection of distillate. It is used to separate the components of a liquid from non volatile solids or those liquid having different boiling points which will be seen on this experiment. (Abdullah, M.G. et. al (2013, December 15) distillation. http://www.britannica.com/EBchecked/topic/166098/distillation) This method is used to
