distillation using a short path column. After this we weighted the product and found the IR. OBSERVATIONS As the solution boiled in the first step it kept changing color getting darker from clear to yellow to orange. During the boiling I can see the two layers forming separating into organic and aqueous with a line in between‚ as the solution boiled more and more the organic phase kept growing little by little. In the final filtration‚ after 20ml of collected organic phase we did a short path

e Meghan Lichtenwalter Intro To Human Communication April 4‚ 2013 The Way We See Me The way I see myself definitely varies from one degree to another. For instance‚ I am not at all tactful as I am imaginative. This is another reason why I perceive myself as being slightly quiet. I chose these answers because I know that I like to think a lot to myself and am more observant of others around me than I am of myself. Since I am rather quiet‚ I haven’t really practiced my communication skills

Nosferatu I rated this film among the ones that I found myself genuinely entertained by. The first thing that stood out about the film was I was able to appreciate it for what it was. I was surprised that I had a genuine reaction of fear to some of the things that were happening on screen. It was done so well in my eyes it made me speculate that perhaps the era of horror films is over and it was only done right in its prime. Everything about the story and the element of creepiness and suspense

complex reactions and reaction sequences‚ where raw materials react together to give the product. Such chemical process often releases energy‚ in the form of heat‚ and the reaction is described as exothermic. Many of these reactions may also evolve gases at high rates‚ and could cause reactor over-pressure. Thermal runaway reaction Runaway reactions are thermally unstable reactions where the heat of reaction can raise the temperature of the reactants sufficiently to accelerate the reaction rate out

International Coastal Clean-up Reaction Paper Ocean Conservancy’s International Coastal Cleanup is the world’s largest volunteer effort for ocean’s health. Each year‚ thousands of volunteers from around the globe participate‚ clearing tons of trash from coastlines‚ rivers and lakes and recording every piece of trash collected. On a beautiful‚ hot‚ sunny and a little bit rainy Saturday‚ we participated in the Annual International Coastal Cleanup at Freedom Island near the Manila-Cavite Expressway

Elimination Reactions ________________________________________ As described previously‚ primary alkyl halides generally undergo substitution reactions with simple nucleophiles by an SN2 mechanism. Secondary alkyl halides‚ often react with simple basic nucleophiles to give a mixture of products arising from both substitution and elimination. As with substitution reactions‚ the rate at which elimination reactions proceed can be proportional to both the concentration of the base and the concentration

Polymerization reaCTIONS polymers are high-molecular-weight compounds‚ fashioned by the aggregation of many smaller molecules called monomers. Ex. plastics that have so changed society and the natural and synthetic fibers used in clothing are polymers. Classification of polymers Homopolymers - consist of repeated long chains or structures of the same monomer unit. Ex. PVC(polyvinyl chloride) Copolymers - polymers that consist of more than one molecule. Trimers - molecules consisting
