The analyses of the mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques, we examined our solutions such as SiO2 (sand), NH4Cl (ammonium coloride), and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions, we made…
Carbon Fiber-Reinforced Composite
Chemistry

Nature
“A carbon fiber is a long, thin strand of material about 0. 005-0. 010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for…

Chemical Elementss Essay, Research Paper At first glimpse, nature appears to dwell of infinite Numberss of really different stuffs. The universe therefore appears to be an highly complex mixture of many different stuffs. But philosophers and scientists have long held another position of the universe. They have found it hard to believe that nature is…

The aim of this investigation was to find the stress intensity that was present when a finite analysis of a cracked plate was conducted. The results that were gained from using the software, ANSYS, were verified with theoretical hand calculations. The stress intensity (KI) was found to be 0.42 Pam1/2 using the finite element analysis…
The Macroscale Synthesis of 1-Bromobutane from 1-Butanol by an Sn2 Reaction
Chemistry
Distillation
Water
This is carried out via an SN2 reaction because the use of an alkyl-halide, Primary in the presence of a strong nucleophile, electrophile as well as substrate, with the reagents chosen this reaction as well as substrate, with the reagents chosen this reaction mechanism is the most favorable. The bromide ion from hydrobromic acid acts…

To set the ammonia fountain experiment up I made sure I had all the materials the lab required me to have which was: a Florence Flask, a 600 mL beaker, a Mohr pipet, distilled and tap water, a polyethylene wash bottle, a phenolphthalein indicator, concentrated ammonium hydroxide, sand, a heating mantle, a ring stand, clamps,…
Determining the Molarity of Acetic Acid in Vinegar Abstract
Chemistry
This experiment was done to determine the molarity of acetic acid in vinegar. The acetic acid in vinegar was titrated with a strong base sodium hydroxide to determine the equivalence point of this chemical reaction. The indicator phenolphthalein was used because the moment it changes color is on the basic side of the pH scale….
6 Health Benefits of Vitamin C
Chemistry
Physical
Vitamin C or ascorbic acid is one of the most studied vitamins in the last 50 years. A search of the scientific literature reveals that over 53,000 studies have been done on vitamin C since 1968. According to these studies, vitamin C promotes strong immunity, is good for the cardiovascular system, brain and skin, and…
Chemical Equilibrium: Experiment
Chemistry
Introduction In this experiment, you will study some metals and some nonmetals to find their relative reactivity. A ranking according to reactivity is called an activity series. For example, an activity series containing the elements calcium, gold and iron would put the reactive calcium at the top, iron in the middle, and the unreactive gold…

DistillationAndrea PausmaOctober 1, 2001I.IntroductionThe process of distillation has been used by humans for years to create alcoholic beverages. Distillation is the process of boiling a pair of liquids with different boiling points and then condensing the vapors above the boiling liquid in an attempt to separate them. One might suspect that the mixed two liquids…
