Classroom Seating Arrangements By: Walaa Samir Fayek Classroom management is extremely effective to create a better learning environment‚ in which the teacher invests in space‚ time and materials to achieve academic and personal development to the students. Personally‚ seating arrangements play a significant role in creating a stress-free and a beneficial atmosphere for the EFL learners and helping the teacher in controlling the class easily. It will also reflect their performance in the activities

Molecule Assignment Parmvir Deo The molecule that I chose was creatine Creatine’s organic role cannot be disparaged. It assumes a key biological role for mammals‚ fish‚ reptiles and amphibians. Creatine helps muscles in delivering adenosine triphosphate (ATP)‚ the substance that facilitates blasts of energy down to the cellular level. Creatine is put away in muscle cells as phosphocreatine and is utilized to produce cell vitality for muscle compressions. The phosphate of ATP is exchanged to creatine

nigerina (nigerine) from the root bark of jurema preta‚ that is‚ Mimosa tenuiflora.[11][12][13] However‚ in a careful review of the case Jonathan Ott shows that the empirical formula for nigerine determined by Gonçalves de Lima‚ which notably contains an atom of oxygen‚ can only match a partial‚ "impure" or "contaminated" form of DMT.[14] It was only in 1959‚ when Gonçalves de Lima provided American chemists a sample of Mimosa tenuiflora roots‚ that DMT was unequivocally identified in this plant material

Exercise 1 Polymers – An introduction to Organic Chemistry Group 3 Jude Marchoni C. Tampus Meryl Marie Susan Chua Pearl Pontillas Paolo Pepito Gaia Casas I. Abstract: (Paolo) In this experiment we will be testing what would happen to the polymer when we add borax to it. A polymer is a compound made up of large molecules often in a solid state. Polymers are chemically formed by 100 to 10‚000 small molecules called "monomers". Monomers occur in molecular units or patterns

The Separation and Purification of Organic Compounds Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient
