Lab 5: Preparation of Synthetic Banana Oil September 20th‚ 2012 Purpose: The main purpose of this experiment was to synthesize banana oil (isopentyl acetate.) Ester are often prepared by the Fischer esterification method‚ which involves heating a carboxylic acid with an alcohol in the presence of an acid catalyst. Theory: Synthesize isopentyl acetate by combining isopentyl alcohol with acetic acid and sulfuric acid and then heating the reaction mixture under reflux for an hour. The alcohol

Objective:- The aim of this experiment was to find the molar mass of unknown volatile liquid under known temperature and pressure. Introduction Molar mass or gram molar mass is the mass of the substance under consideration without distinguishing whether a substance is an element ‚ a molecule or an ionic compound. These elements‚ molecules or ionic compound could be solid gas or liquid. The molar mass of gas or vapor could be measured if the gases obey the law of Ideal Gas . The mass of

The Dust Bowl of the 1930’s had such an antagonistic effect on the United States economy that was already plummeting. The Dust Bowl affected the U.S economy in just about every way possible ranging from agriculture to finances including government expenses to population changes. This phenomena can be considered as one of the worst natural disasters that has affected the United States. The “Dust Bowl” was the name given to the Great Plains region that was greatly affected by drought in the 1930’s

Is glass a solid or a liquid "The idea that glass is a fluid is a very widespread myth." (Yvonne Stokes:1999‚Discover Magazine) This myth has survived for centuries because glass is such a confusing matter which cannot be compared to the three ordinary kinds of matter described in our particle theory of matter. Gasses contain free flowing molecules which are much further apart then liquids and gasses which removes the possibility of glass being a gas. A liquid however contains tighter bound molecules

Legend of the Banana Plant In the early days when the world was new‚ spirits and ghosts lurked everywhere. They lived in gloomy caves‚ they hid in anthills and tree trunks they frolicked in nooks and corners under the houses.

It was during these days of phantoms and unseen spirits that a young and beautiful girl lived. Her name was Raya‚ and she was a girl bold and daring

Dust being carried and swept all around your home and town basically describes The Dust Bowl. The Dust Bowl led to a major decline in an area’s population because large numbers of people moved‚ people left to go to safe states‚ people lost jobs‚ and the number of storms affected the population. To start things off‚ the first reason the population declined is because large numbers and groups of people moved during The Dust Bowl. “Recurrent dust storms wreaked havoc‚ choking cattle and pasture lands

PCP: Angel Dust Hallucinogens include drugs that are fascinating yet have alarming effects on a user. According to Gaines and Kremling (2014)‚ “In contrast to antidepressants that make the neurotransmitter serotonin linger in the gaps between brain cells‚ hallucinogens push the serotonin system into overdrive. Hallucinogens amplify signals from a person’s sensory perception‚ distorting form and size. Users often talk about “seeing sounds‚” or “hearing visual stimuli” (p. 129-130).” Hallucinogens

Throughout their lecture‚ Trevor Copp and Jeff Fox discuss and demonstrate their newly created dance technique called “Liquid Lead” and explain how this technique can help do away with the outdated idea that ballroom dances have perpetuated for years: that the man leads and the woman follows. The technique of “Liquid Lead” can be described as taking turns between partners both leading and following‚ and switching between these roles whenever felt needed during a dance. During their Ted Talk‚ Copp
