Red Bull and Sugar Free Red Bull NMR Post Lab Report Abstract Viewed as one of the most significant tools in analytical chemistry‚ the Nuclear Magnetic Resonance (NMR) is a spectroscopy tool often used by chemists to determine the molecular profile – quality and quantity of the major components - of any given organic substance. Operating on basis of spectroscopy (study of the interaction between matter and radiated energy - Harris)‚ the NMR can be either a one (1H NMR) or two (1H/13C NMR) dimensional

Acetylsalicylic Acid (Aspirin) Synthesis Telow‚ AJV Sumicad‚ CJ‚ Tavanlar‚ EMMT‚ Chem 40.1‚ Institute of Chemistry‚ University of the Philippines Los Baños I. Introduction Organic synthesis is the process where a desired organic compound is constructed or prepared from commercially available materials. The objective of organic synthesis is to design the simplest synthetic routes to a molecule. Aspirin‚ also known as acetylsalicylic acid is as salicylate drug often used as analgesic

by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example

bEAN BAG ISOTOPES:ABUNDANCE AND ATOMIC MASS LAB By: Catriona Whalley Partner: Ming Siegel Due: 1.14.10 Prelab A new atomic theory‚ in which all atoms of the same element are identical to one another and equal in mass‚ was proposed by the scientist Dalton. Although the theory had its flaws and was simple‚ it was revolutionary. Scientists became able to study the actual structure and mass of atoms after the discovery of radioactivity. Soon‚ isotopes were discovered‚ as atoms of the same element

Step 2: My hypothesis was that the bag with 60% sucrose then it would be heavier than the bag with tap water or 30% sucrose. I thought this because I thought that there would be more of a substance change in 60% sucrose. Section 3: Methods First get 3 pieces of the same

How Acetylsalicylic Acid was Discovered Acetylsalicylic Acid in its earliest form was a powder for the bark and leaves of the willow tree. Hippocrates‚ who lived sometime between 460 B.C. and 377 B.C‚ founded it. This “Miracle Drug” that was able to relieve pains was later looked into with further detail by Johann Buchner. He isolated a tiny amount of bitter tasting yellow‚ need- like crystals‚ and called salicin. By 1829 French Chemist Henri Leroux had improved the extraction procedure to
