BIO 101 LABORATORY Activity No.: 4 Movements of Materials Across Membrane I. INTRODUCTION Many important reactions and processes in materials occur by the motion of atoms in the solid (transport)‚ which happens by diffusion. Inhomogeneous materials can become homogeneous by diffusion‚ if the temperature is high enough. When substances are brought in contact with

I. INTRODUCTION Synthesis Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel‚ 2011)‚ Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid’s hydroxyl group

When the word silence is used by Shusaku Endo it is to represent a lack of action. Rodrigues is a very devout Christian who has dedicated his entire life to helping those in need and helping spread the knowledge of his religion. Throughout his journey he finds himself in the opposite situation. He finds himself to be the cause of pain and suffering‚ brought on by the Japanese government and Inoue in particular. Silence is a story of transformation; not only physical transformations but mental

they have restricted rotation around the double bond so they tend to form the cis and trans geometric isomers. While both of these isomers have the same molecular formula‚ they usually vary in many physical features. Cis isomers have two identical groups located on the same side of the double bond‚ while trans isomers have the two groups on opposing sides of the molecule. Trans isomers are usually more stable than cis isomers because there is no steric interaction‚ or repulsion‚ between the carboxyl

Purpose: To synthesize 1‚2‚3‚4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared
