Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

Jennifer Everett Phase 4 DB Instructor: Clement Yedjou 3/10/2015 Acid rain Acid rain is a result of air pollution that is harmful to the environment‚ generally caused by fuels being burnt. When any type of fuel is burnt‚ many different chemicals are produced. These gases that are released react with the water in clouds‚ and the rain from these clouds is acid rain. This type of acid disposition can appear in many other forms besides just rain‚ such as sleet‚ snow‚ and fog (Editorial Board‚ 2013)

GIVEN: TO DESIGN A 1000TPD CAPACITY H2SO4 ACID PLANT BASIS: 1 HOUR OF OPERATION. PURITY: PRODUCT WHICH IS TO BE MANUFACTURED IS ASSUMED TO HAVE STRENGTH OF 98% ACID. 1000TPD implies that we have Acid 1000 x 10 / 24 = 41666.67 Kg/Hr of 3 With 98% purity‚ the acid that is produced per hour = (98 x 41666.67) / 100 = 40833.34 Kg/Hr Kmoles of Sulfuric acid to be produced = 40833.34 / 98 = 416.667 Kmoles/Hr It’s assumed that overall absorption of the acid is 100 % = 416.667 / 1.0 Then‚ SO3 required

A Clockwork Orange Authors who write of other times and places help us to better understand our own lives. Discuss A Clockwork Orange in terms of that statement. A "clockwork orange" can be described as something that has a convincing outer appearance yet in the inside is merely controlled by outer influences‚ such as a clock set in motion by its owner. In A Clockwork Orange‚ Anthony Burgess takes us into the future where violent criminals are forced to be "good‚" and introduces us to

Content and Development Juvenile delinquency is a major problem effecting our youth. Despite how much we try to prevent it‚ some of our youth will end up in the juvenile justice system. There are always debates on whether we should focus on punishment or rehabilitation. Rehabilitation focuses on the treatment of the juvenile with the assumption that interventions such as probation supervision‚ work readiness‚ training‚ cognitive skills training‚ and behavior therapy will change

on biological thinking as the discovery of base-pairing in nucleic acids. These complementariness principles do not only underlie current ideas on the structure of the nucleic acids‚ but they form the foundation of all speculations‚ more or less well- founded‚ on their physical properties (denaturation‚ hypochromic- ity‚ etc.)‚ on the transfer of biological information from deoxy- ribonucleic acid to ribonucleic acid‚ and on the role of the latter in directing the synthesis of specific

The girl with the orange bow‚ built up her courage and moved her cart towards the bag boy’s checkout line. “Hey there!” The girl in the orange bow grew nervous and her heart was pounding faster than it should be. It was pounding like if she just finished running a mile. “Hello miss. How may I assist you?” The bag boy cleared up his throat and smiled at the girl. He adored her. Everything about her he loved. Especially her eyes and her bow almost spoke out her personality. He couldn’t keep his
