Identification and Production of Materials ================================ Ethene‚ Polymers and Ethanol ================================ Catalytic Cracking Oil refineries need to balance their outputs of various products (petrol‚ diesel‚ fuel oil‚ etc.) to match the demands of the marketplace. Catalytic cracking is the process in which high molecular weight (high boiling point) fractions from crude oil are broken into lower molecular weight (lower boiling point) substances in order to increase

purposes? 1.0 Introduction and chemistry background Plastic or its scientific name polyethylene is a type of polymer. Polymers are defined as a large molecules consisting of specific small repeating monomers that combine or react together. In this case‚ plastic or polyethylene is made up of small monomers called ethylene (ethene). Ethylene molecules react and combine together through addition reaction/polymerization (double bond of ethylene breaks in the reaction) and finally form polyethylene. Basically

Introduction In this experiment‚ glucose‚ maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are formed from the condensation reaction between two monosaccharaides and are linked by glycoside bond. All monosaccharaides and some

vertebrates‚ and are used by the immune system to identify and neutralize foreign objects‚ such as bacteria and viruses. They are typically made of basic structural units—each with two large heavy chains and two small light chains—to form‚ for example‚ monomers with one unit‚ dimers with two units or pentamers with five units. Antibodies are produced by a kind of white blood cell called a plasma cell. There are several different types of antibody heavy chains‚ and several different kinds of antibodies‚

Chapter I INTRODUCTION Plastics found everywhere. Bottles‚ utensils‚ food packagings are some examples of plastics that we use and see in our daily lifestyle. We can easily have plastics for our convience because it was sold in our market directly thus spending a little of our money. Behind these things our typical perception about plastic is just a bit of what plastics really are. For those people who are concious about our environment ‚ they say that plastics cause a wide environmental problem
