broken down by reacting it with water. Esters are hydrolysed by acid hydrolysis or alkaline hydrolysis. Acid hydrolysis involves boiling the ester with dilute aqueous acid (H2SO4 or HCl) while the latter involves boiling the ester with an aqueous alkali (KOH or NaOH). The products of acid hydrolysis are an alcohol and carboxylic acid. Alkaline hydrolysis yields a salt (called the salt of the acid) and the alcohol that formed the ester. Both types of hydrolysis were performed in this experiment

The importance of calcium and phosphorus is that they play a role in the body and their role is to build bones and teeth this is because they allow rigidity to the structure of the bones and teeth. This is because bones are continuously being rebuilt with new bone being formed and also teeth as well but at a slower rate but this is why calcium and phosphorus is needed and is important. The role of calcium is that it circulates blood and it also helps blood clot in other body tissues and also plays

controlled to limit emissions and to limit bed material agglomeration." Agglomeration can be caused by alkaline ash‚ other metals‚ and phosphates combining with alumina and silica to form low-melting-point eutectics that coat the bed particles. If alkali concentrations are too high the coatings melt and bond the particles together; these larger agglomerated particles become too heavy and interfere with the fluidization process. CFB technology provides fuel flexibility in that it can burn wood and

Summary Researchers typically use a batch reactor to study reaction kinetics under ideal conditions. This experiment was carried out in other to study effect of temperature on reaction rate constant and also to study the effect of the reaction rate constant in a batch stirred tank reactor its important in chemical industry because it is used to determine the effect of temperature on reaction rate constant; it is also used in chemical and process industry for solids dissolution‚ product mixing‚ chemical

AIM The aim of this investigation is to explore the effect of different concentrations of bile salts on the time taken for the lipase enzyme to break down fat. BILE Bile is a brownish bitter alkaline fluid produced by the liver and made by the hepatocytes from water‚ bile salts‚ bile pigments cholesterol and phospholipids and stored in the gall bladder. Bile is directly connected with digestion. It is released sporadically into the small intestine (duodenum) which is part of the gut in order

Abstract The article describes a technique for processing liquid radioactive waste water using membrane techniques to single out only radioactive waste components without affecting the salt ballast. This solution dramatically reduces the amount of radioactive concentrates to be long-term storage‚ and provides an opportunity to re-use treated water and chemicals. Keywords. Liquid radioactive waste‚ radioactive waste water purification‚ reverse osmosis‚ selective extraction of radionuclides. Introduction

Creation of Oahu by Volcanism Karen Ta: 430 BOT 450 TR 10:30-11:20 Volcanoes are magnificent formations from an opening in a planet’s crust. They form when magma‚ volcanic ash‚ and gases escape from a magma chamber below the surface of the planet. Tectonic plates cover the surface of the planet and are constantly moving. Volcanoes are generally found where these plates converge or diverge. Not only are volcanoes found in these areas but also where the Earth’s crust is stretching or thinning

Milk-and-alkali tetany is an example of this imbalance. Underfunction of the parathyroid gland can lead to tetany. Low levels of carbon dioxide cause tetany by altering the albumin binding of calcium such that the ionised (physiologically influencing) fraction
