mummion assignment Task 1 – purification Aim We were given a sample of mummion in the form of dried mud from a lake; the aim of the practical was to purify the sample and separate it from the insoluble impurities into the form of mummion salt. Context A long time ago mummion was used to preserve the bodies of ‘mummies’ in ancient Egypt‚ mummion along with other naturally occurring preservatives was used to treat the organs before the bodies were wrapped. This purification practical happens very often

Music Appreciation April 30‚ 2013 “The Separation” The separation of church music and secular music during the Baroque period was the beginning of something new. Many people had no idea that the instruments they used during the Renaissance period could do more than they had been doing with them. This brought a new meaning of music and life into the world. It was a great change for music‚ instruments‚ and even people. Church music‚ also known as sacred music‚ was well known in the Renaissance

CHAPTER 6 MECHANICAL-PHYSICAL SEPARATION PROCESSES Introduction Separation Processes Many chemical processes materials and biological substances occur as mixtures of different components in the gas‚ liquid‚ or solid phase. In order to separate or remove one or more of the component from its original mixture‚ it must be contacted with another phase. The two-phase pair can be gas-liquid‚ gas-solid‚ liquid‚ or liquid-solid. Absorption When the two contacting phases are a gas and a liquid

Introduction ESTERS are compounds derived from the reaction of a organic acid with an alcohol. Acid + Phenol/alcohol --> ester + water R--C=O + R’--OH ----> R--C=O + H2O | | C-OH C-O-R’ Esters are the compounds that give fruits their characteristic flavours and odours. ie. methyl salycilate is "Oil of Wintergreen". http://www.petrik.com/PUBLIC/library/misc/glossary_of_org_chem.htm#ESTERS Aim To synthesise the ester 3-methylbutyl ethanoate( isopentyl acetate) and to identify the product

Study of Water Purification Methods Water is the most essential component of life on Earth. In the United States‚ the average person uses about 75 gallons per day of freshwater. Most of this water is pre-treated in facilities and comes out of the tap clean and ready for drinking‚ a fact many take for granted. If you are camping and hiking you won’t always have access to this source of healthy‚ potable water. Unfortunately‚ many water sources in the wilderness include microorganisms‚ bacteria

Nitration and Purification of Bromobenzene Abstract: An electrophilic aromatic substitution reaction was performed on bromobenzene with nitric acid producing both 2-bromonitrobenzene and 4-bromonitrobenzene. Products of the reaction were purified through multiple recrystallizations and column chromatography creating multiple crops of a yellow powder. The percent yield of products was determined to be 51%. The melting point of Crop 1 was found to be 110-115 °C‚ and Crop 2 was found to be 37-90

Deloris Buliner RESL201 Christopher Myers October 20‚ 2014 Purification of Judaism and Hinduism Judaism and Hinduism have different cultures and originate from different ends of the spectrum of religious development. The origin of Judaism is characterized by a dramatic break with the near Eastern religious tradition comprising of the unity of God‚ man‚ and the cosmos while Hinduism on the other hand‚ characterized by “pantheism” as the main motif in its religious outlook (Ridgeon‚ Lloyd).
