1. Omega 3 fatty acids and Alzheimer’s disease Omega 3 fatty acids and Alzheimer’s disease how do they relate to one another? I have found in my research that omega 3 has been proven to show a delay in the process of Alzheimer’s disease and also has many other health benefits. This is my findings in doing my research. Although no one knows what causes Alzheimer ’s disease‚ many research studies indicate that those who regularly eat fatty fish or who supplement with fish oil have a lower

Preparing Esters by esterification method using carboxylic acid to an alcohol‚ which is 1.0 ml of ethanoic acid to the ethanol‚ and ethanoic acid to the propan-1-ol‚ also adding H2SO4 as a catalyst for the reaction Abstract: Esters are a group of organic compound‚ famous for their interesting odours and smells. In this investigation student used ethanoic acid and ethanol with sulfuric acid as catalyst to produce ester‚ which was known of its smell. However it was expected to have a pleasant smell

Title: Measuring the loss in mass of Marble chips and Hydrochloric acid Aim: We will measure the loss in mass of the marble chips (CaCO 3 ) as it reacts with Hydrochloric acid (HCl). This one method of measuring the rate of reaction. We will use a balance to measure this mass loss as the reactants are used up to form product. Safety: * As Hydrochloric acid is corrosive wear a lab coat‚ gloves and safety goggles. * Take care when using the glassware not to cut yourself. * When

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will

The Role of the Citric Acid Cycle The Citric Acid Cycle is a series of enzyme-catalysed reactions that take place in the mitochondrial matrix of all aerobic organisms. It involves the oxidation of the acetyl group of acetyl CoA to two molecules of carbon dioxide. Each cycle produces one molecule of ATP by substrate-level phosphorylation‚ and reduces three molecules of NAD and one molecule of FAD for use in Oxidative Phosphorylation. The cycle is preceded by Glycolysis‚ which also occurs in anaerobic

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

Synthesis of Salicylic Acid and Potentiometric Determination of its Purity and Dissociation Constant ------------------------------------------------- Abstract The purpose of the study is to synthesize salicylic acid from the ester‚ methyl salicylate‚ and determine the acid’s dissociation constant and purity. The ester was converted to salicylic acid by base hydrolysis. The products were refluxed and recrystallized‚ to ensure maximum purity‚ and filtered‚ dried‚ and weighed. The melting point

experiment teaches the students how to determine density‚ volume‚ and percentage errors. OBJECTIVE The objective of this experiment is to determine the order with respect to permanganate ion and to oxalic acid concentration for the reaction of potassium permanganate and oxalic acid solutions. Other goals include‚ writing a rate equation and determining the effect of increased temperature on the rate of this reaction. MATERIALS AND EQUIPMENT The materials required for this experiment include

What is LSD? LSD (lysergic acid diethylamide) is a synthetic (man-made) drug that has been abused for its hallucinogenic properties since the 1960s. If consumed in a sufficiently large dose‚ LSD produces delusions and visual hallucinations that distort the user’s sense of time and identity. LSD typically is sold as a liquid or applied to blotter paper‚ sugar cubes‚ gelatin squares‚ and tablets. LSD generally is taken by mouth. The drug is colorless and odorless but has a slightly bitter taste.
